These performance downpipes are constructed from high-strength 304 stainless steel, replacing the factory's restrictive exhaust components.\n\nFeaturing high-flow, 200-cell sport catalytics, these downpipes are designed to reduce back pressure, increase exhaust gas volume, and deliver a richer sound. When combined with RENNtech's ECU software, they aim to provide significant performance gains and an enhanced auditory experience. The kit includes all necessary mounting hardware and clamps, ensuring a perfect fit with the stock CL Class exhaust system.\n\nThese downpipes are listed to provide an estimated gain of +10 HP and +15 LB-FT of torque.","brand":"Renntech","offers":[{"title":"Default Title","offer_id":52663472161080,"sku":"49.157.0365","price":4940.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687612780.jpg?v=1784327229","url":"https:\/\/store.motormia.co\/products\/304-stainless-steel-downpipes-with-200-cell-sport-catalytic","provider":"MOTORMIA","version":"1.0","type":"link"}
