Thus, removing as many exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into \"honeycomb\" weaves. Exhaust gas must pass through these tiny \"honeycomb\" weaves on its way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction).  By replacing the factory downpipe \/ catalytic converter with our Extreme Online Store Competition Series 4\" Race Cat Downpipe, more power is unleashed and You will feel the difference instantly. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOur Competition Series Race Cat Downpipes is constructed out of 100% 304-grade stainless steel and utilizes mandrel bent piping. They are 100% TIG welded by our in-house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor is positioned at the factory location. Since the outlet of the turbocharger is 3.5\" and the factory exhaust system is 3\", the factory downpipes reduce size using short transitions from 3.5\" before the catalytic convert and 3\" afterward. Due to the space needed for the catalytic converter, the factory downpipes reduce in size using very short transitions. Since our Race Cat \u003c\/span\u003e\u003cspan\u003edownpipes delete the catalytic converter, we have more space. Thus, we use very long transitions.  These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller. Also, since we utilize a larger 4\" pipe right after the turbocharger, turbo back pressure is significantly reduced. This results in less exhaust turbulence and backpressure which again improves throttle response and increases turbocharger spool times (less turbocharger lag). \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eHigher Max Horsepower Power Curve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHigher Initial Torque Curve - The torque curve hits faster and higher and longer\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBetter throttle response and faster turbo spool-up times\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMandrel Bent 4\" piping With Smooth transition to the exhaust system\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e100% Stainless Steel Construction\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e100% TIG welded for better quality welds\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePrecision CNC machined turbocharger V-Band flange\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCompatible with the factory or aftermarket exhaust systems\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTrack tested durability With Limited Lifetime Warranty\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eExpected gains of 20whp and 30wtq when used with a Stage 2 Tune\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"color: #ff2a00;\"\u003eDue to California Vehicle Code Section 27156, we are NOT Able to Ship this Item to any CA Address ( Order will be Cancelled for ALL CA Address )\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"color: #ff2a00;\"\u003eThis Item is Designed for Off-Road Use ONLY - Might Cause a CEL Check Engine Light.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"color: #ff2a00;\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/VFtY-5mY7mI?si=DTKjL8yfKqspArtx\" height=\"315\" width=\"560\"\u003e\u003c\/iframe\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003e\u003cstrong\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1910\/0467\/files\/WhyShopSixity-Banner-Auto-20160323_large_2f679a66-c56f-409b-82d4-1ac13835f6f9_large.jpg?v=1534804814\" alt=\"ExtremeOnlineStore | EOS Corvette C7 Carbon Fiber Front Splitter Lip Side Skirts Rear Spoiler aero performance body kit bolt on OEM replacement | Best Price Free Shipping\"\u003e\u003c\/strong\u003e\u003c\/h6\u003e","brand":"Extreme Online Store","offers":[{"title":"T-304 Stainless Steel","offer_id":40446355996842,"sku":"EXT-DP017","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1910\/0467\/products\/W0_96380ed1-5038-4b8d-9b90-17f79cdfaa22.jpg?v=1753741798"},{"product_id":"3010-32024","title":"AWE Touring Edition Axle Back Exhaust for BMW F3X 335i\/435i - Chrome Silver Tips (90mm)","description":"\u003cp\u003eHundreds of hours of research, prototyping, engineering, testing, and daily usage evaluation plus over two decades of performance engineering for European autos has yielded the ultimate exhaust for the BMW F30 335i.
