         Lake Forest, Illinois, July 22, 2003 -- Tenneco Automotive (NYSE: TEN)
         announced today that the company reported net income of $24 million, or
         58-cents per diluted share, in the second quarter of 2003, versus net
         income of $19 million, or 45-cents per diluted share for the second
         quarter of 2002. EBIT (income before interest, taxes and minority
         interest) was $67 million in the quarter compared with $71 million in
         second quarter 2002. EBIT before depreciation and amortization (EBITDA)
         was $108 million for the quarter, versus second quarter 2002 EBITDA of
         $106 million. See the table entitled, "Reconciliation of GAAP Results
         to non-GAAP Results" which is attachment 2 to this press release for
         more information about EBITDA and other non-GAAP results in this press
         release.

         The company reported revenue of $998 million for the quarter versus
         $948 million in second quarter 2002. Excluding a $76 million benefit
         from favorable currency exchange rates during the quarter, second
         quarter 2003 revenue was $922 million. The decline in revenues, after
         excluding the currency benefit, was primarily driven by softer global
         aftermarket sales. Global original equipment (OE) revenue was down only
         1 percent, after currency adjustments, stronger than the industry
         market performance.


                                       1

         "We are pleased with our ability to deliver our sixth consecutive
         quarter of year-over-year improvement, despite overall industry
         conditions that are average at best. This consistent performance
         reflects our commitment to growth and improving the fundamentals of our
         business, " said Mark P. Frissora, chairman and CEO, Tenneco
         Automotive. "We are particularly encouraged with our progress in
         Europe, where we believe our OE business is back on track now that the
         emissions control business has substantially recovered."

         The company captured savings in the quarter through a continued intense
         focus on controlling costs. SGA&E (selling, general, administrative and
         engineering expense), as a percent of sales, was 11.0 percent, compared
         with 11.6 percent in the second quarter of 2002. Project Genesis, the
         company's restructuring program, generated $7 million in savings in the
         second quarter, bringing the year-to-date savings to $13 million. The
         company anticipates total annualized savings of $27 million from
         Project Genesis in 2003. The company also generated almost $7 million
         in savings from Six Sigma, $13 million in savings year-to-date, and is
         well on track to meet its goal of $20 million in Six Sigma savings for
         the year.

         The second quarter 2003 results include a pre-tax restructuring related
         expense of $1 million, or 3-cents per diluted share, a pre-tax expense
         of $5 million, or 7-cents per diluted share, related to the write-off
         of debt issuance costs that were deferred on the senior debt the
         company paid down with the proceeds of a $350 million bond offering,
         and a tax benefit of $8 million, or 19-cents per diluted share, related
         to a favorable tax resolution. The second quarter 2002 results include
         a pre-tax benefit of $11 million, or 13-cents per diluted share, for
         the sale of the company's York, U.K. manufacturing facility and a
         pre-tax restructuring related expense of $2 million, or 2-cents per
         diluted share.

         The company continues to win new business with global original
         equipment manufacturers. The company won 18 new OE business awards in
         the quarter estimated to add $147 million of incremental revenue over
         five years beginning in 2003, including being selected as the full
         service exhaust supplier for the Ford gas and diesel 2007 model year
         F-Series Super-Duty truck. On the aftermarket side, the company added
         new business worth an estimated $11 million in annualized revenue with
         new customers in Europe and North America.

         "Our business units have a renewed emphasis on growth this year, and we
         delivered some strong results this quarter," Frissora said. "The
         shrinking exhaust aftermarket worldwide continues to have the greatest
         impact on our aftermarket results. We are offsetting some of this
         downturn by adding incremental business and not letting up on our
         efforts to do everything possible to take out costs, especially in
         distribution."

         Cash flow before financing activity was a negative $35 million during
         the second quarter 2003. Negative cash flow during the quarter was
         driven by increased


                                       2

         working capital and higher tax settlement costs. Due to the seasonality
         of its business, cash use is typically higher in the second quarter as
         the company moves into the spring and summer selling seasons in the
         aftermarket. While working capital increased overall, the company made
         substantial progress toward its inventory reduction goals, generating
         $36 million in cash flow from reduced inventories. Total borrowings
         increased $54 million during the quarter, which included $12 million in
         fees paid in connection with the $350 million senior secured note
         offering. Tenneco Automotive's total bank and bond debt was $1.497
         billion at the end of the second quarter 2003.

         Tenneco Automotive again significantly outperformed the requirements of
         its bank debt covenants. At June 30, the leverage ratio was 4.56, below
         the maximum limit of 5.50; the fixed charge coverage ratio was 1.32,
         exceeding the minimum required ratio of 0.90; and the interest coverage
         ratio was 2.33, exceeding the minimum required ratio of 1.75.

         NORTH AMERICA
              o   Softer OE production during the quarter contributed to a 7
                  percent decrease in North American original equipment revenue
                  to $365 million versus second quarter 2002 revenue of $391
                  million. The decline was driven in part by lower precious
                  metal prices on pass-through catalytic converter sales. The
                  company's continued strong position on top-selling platforms
                  helped offset the even larger overall industry decline in
                  sales.

              o   North American aftermarket revenue was $136 million versus
                  $148 million one year ago. The 8 percent decline was primarily
                  the result of a 17 percent decline in the aftermarket exhaust
                  business.

              o   EBIT for North American operations was $49 million compared
                  with $53 million in the second quarter of 2002, which included
                  $1 million in restructuring related expenses. EBIT was
                  impacted by the continued decline in the exhaust aftermarket
                  and, to a lesser extent, lower OE volumes. Improved
                  manufacturing efficiency and continued emphasis on controlling
                  costs helped partially offset these factors.

         EUROPE
              o   European original equipment revenue increased to $286 million
                  in the quarter versus $231 million in second quarter 2002.
                  Before catalytic converter pass-through sales and the impact
                  of favorable currency exchange rates, revenue was still up 5
                  percent, versus an estimated industry decline of 4 percent.
                  The revenue increase was driven by the company's position on
                  top-selling vehicles and the launch of several high-volume
                  platforms.

              o   European aftermarket revenue was $102 million compared with
                  $90 million in the second quarter of 2002. Excluding the
                  impact of favorable


                                       3

                  currency, second quarter 2003 revenue was $84 million. The
                  decrease was driven by the industry decline in the exhaust
                  segment.

              o   European EBIT was $11 million, flat year-over-year. EBIT for
                  the quarter includes $1 million of restructuring related
                  expense and $4 million of favorable currency effects. Second
                  quarter 2002 EBIT includes an $11 million gain on the sale of
                  the York, U.K. facility and restructuring related expenses of
                  $1 million.

              o   Before these items, EBIT improved significantly, primarily
                  driven by improved operational efficiencies throughout the
                  European operations, particularly in the original equipment
                  emissions control business, where gross margin increased
                  almost 5 percentage points from the prior year. Project
                  Genesis savings added $4 million to earnings but were
                  substantially offset by the impact of lower aftermarket sales.


         REST OF WORLD
              o   Revenue from Asian operations increased 36 percent to $40
                  million in the quarter. New business and strong OE volumes in
                  China continue to drive the growth.

              o   In South America, the company reported revenue of $29 million,
                  an increase over $28 million in second quarter 2002. Currency
                  devaluations in both Brazil and Argentina had a $2 million
                  negative impact on revenues.

              o   The company's Australian operations reported revenues of $40
                  million compared with $31 million in second quarter 2002, a 32
                  percent increase. Strong volumes on key platforms and a
                  favorable currency exchange rate of $7 million impacted
                  revenues.

              o   Combined EBIT for Asia, South America and Australia was $7
                  million, flat with the previous year. Weak economic conditions
                  in key South American markets offset higher revenues and EBIT
                  gains in China.


         Tenneco Automotive closed on its bond offering of $350,000,000 of 10.25
         percent senior secured notes in the quarter, which provides liquidity
         and greater financial flexibility going forward. The company used
         proceeds from the notes to pay off $87 million of borrowings under its
         revolving credit facility and to repay $251 million in senior term
         loans that were amortizing at the rate of $94 million annually through
         2005. The company incurred $12 million in costs to complete the
         offering and expects to incur up to $19 million in higher annual
         interest expense. The notes are senior secured obligations of Tenneco
         Automotive and


                                       4

         those subsidiaries that guarantee the notes, and will mature on July
         15, 2013 with interest payable semi-annually beginning on January 15,
         2004.

         "We are very pleased with the successful completion of our bond
         offering and the positive response from the financial community. We
         believe the success of this offering contributed in part to the 59
         percent rise in our stock price and the significant rise in trading
         value of our other debt instruments during the quarter," said Frissora.
         "This refinancing transaction provides Tenneco Automotive with
         long-term financial flexibility to address our primary goal of total
         debt reduction. At the same time, the $87 million revolver pay down and
         the deferral of debt amortization payments of over $210 million through
         2005 strengthens the company's near-term liquidity, giving us
         sufficient resources to adjust to market uncertainties as we continue
         to implement strategies to grow the top line of our business and
         improve our operating performance."

         The company also announced today a change to its retiree medical
         benefits program, which will provide participating retirees with
         continued access to group health coverage while reducing Tenneco
         Automotive's subsidization of the program. Based on current estimates,
         the company anticipates that this change will increase its net income
         by approximately $7 million annually, beginning in the third quarter of
         2003.

(1) Generally Accepted Accounting Principles

(2) Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
    results in order to reflect the results for the second quarters of 2003 and
    2002 in a manner that allows a better understanding of the results of
    operational activities separate from the financial impact of decisions made
    for the long-term benefit of the company. Adjustments similar to the ones
    reflected above have been recorded in earlier periods, and similar types of
    adjustments can reasonably be expected to be recorded in future periods.
    Using only the non-GAAP earnings measure to analyze earnings would have
    material limitations because its calculation is based on the subjective
    determinations of management regarding the nature and classification of
    events and circumstances that investors may find material. Management
    compensates for these limitations by utilizing both the GAAP and non-GAAP
    earnings measures reflected above to understand and analyze the results of
    the business. The company believes investors find the non-GAAP information
    helpful in understanding the ongoing performance of operations separate from
    items that may have a disproportionate positive or negative impact on the
    company's financial results in any particular period.

(3) EBITDA represents income before cumulative effect of change in accounting
    principle, interest expense, income taxes, minority interest and
    depreciation and amortization. EBITDA is not a calculation based upon
    generally accepted accounting principles. The amounts included in the EBITDA
    calculation, however, are derived from amounts included in the historical
    statements of income data. In addition, EBITDA should not be considered as
    an alternative to net income or operating income as an indicator of the
    company's operating performance, or as an alternative to operating cash
    flows as a measure of liquidity. Tenneco Automotive has presented EBITDA
    because it regularly reviews EBITDA as a measure of the company's ability to
    incur and service debt. In addition, Tenneco Automotive believes its debt
    holders utilize and analyze our EBITDA for similar purposes. Tenneco
    Automotive also believes EBITDA assists investors in comparing a company's
    performance on a consistent basis without regard to depreciation and
    amortization, which can vary significantly depending upon many factors.
    However, the EBITDA measure presented may not always be comparable to
    similarly titled measures reported by other companies due to differences in
    the components of the calculation.

(1) Generally Accepted Accounting Principles

(2) Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
    results in order to reflect the results for the first half of 2003 and 2002
    in a manner that allows a better understanding of the results of operational
    activities separate from the financial impact of decisions made for the
    long-term benefit of the company. Adjustments similar to the ones reflected
    above have been recorded in earlier periods, and similar types of
    adjustments can reasonably be expected to be recorded in future periods.
    Using only the non-GAAP earnings measure to analyze earnings would have
    material limitations because its calculation is based on the subjective
    determinations of management regarding the nature and classification of
    events and circumstances that investors may find material. Management
    compensates for these limitations by utilizing both the GAAP and non-GAAP
    earnings measures reflected above to understand and analyze the results of
    the business. The company believes investors find the non-GAAP information
    helpful in understanding the ongoing performance of operations separate from
    items that may have a disproportionate positive or negative impact on the
    company's financial results in any particular period.

(3) EBITDA represents income before cumulative effect of change in accounting
    principle, interest expense, income taxes, minority interest and
    depreciation and amortization. EBITDA is not a calculation based upon
    generally accepted accounting principles. The amounts included in the EBITDA
    calculation, however, are derived from amounts included in the historical
    statements of income data. In addition, EBITDA should not be considered as
    an alternative to net income or operating income as an indicator of the
    company's operating performance, or as an alternative to operating cash
    flows as a measure of liquidity. Tenneco Automotive has presented EBITDA
    because it regularly reviews EBITDA as a measure of the company's ability to
    incur and service debt. In addition, Tenneco Automotive believes its debt
    holders utilize and analyze our EBITDA for similar purposes. Tenneco
    Automotive also believes EBITDA assists investors in comparing a company's
    performance on a consistent basis without regard to depreciation and
    amortization, which can vary significantly depending upon many factors.
    However, the EBITDA measure presented may not always be comparable to
    similarly titled measures reported by other companies due to differences in
    the components of the calculation.

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical regions, separately from the effects of doing business in
currencies other than the U.S. dollar. Additionally, pass-through catalytic
converter sales include precious metals pricing, which may be volatile. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues.

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical regions, separately from the effects of doing business in
currencies other than the U.S. dollar. Additionally, pass-through catalytic
converter sales include precious metals pricing, which may be volatile. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues.
