The S54 rasp is excessive and tuning it out requires the right combination of resonators, placement, and tubing size. CPI designed their own section 1 after other designs on the market fell short. Rasp is reduced by approximately 80% on a M3 equipped with aftermarket headers.\u003cbr\u003e\u003cbr\u003eThe latest RTX incorporates an H-pipe crossover that equalizes exhaust pressures in both banks before they merge for section 2. This reduces turbulence and improves exhaust flow. While not designed to gain power and torque, dyno testing showed slight gains with this system. Fitment has also been improved for better ground clearance. Tubing is a full 2.36\" (60mm) and 409 stainless steel throughout. It will bolt on to most headers and to any section 2 that uses the factory-style flanges.\u003cbr\u003e\u003cbr\u003eCPI exhaust is now manufactured for BimmerWorld by Magnaflow in California and carries a limited lifetime warranty.\u003cbr\u003e\u003cbr\u003e\u003cfont size=\"3\"\u003e\u003cstrong\u003eVideo:\u003c\/strong\u003e\u003c\/font\u003e\u003cbr\u003eCPI RTX with stock exhaust:\u003cbr\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/MlQ8ZIh52JI?rel=0\" frameborder=\"0\" allow=\"autoplay; encrypted-media\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFitment Notes:\u003c\/strong\u003e\u003cbr\u003e2001-2006 E46 M3: no notes, direct fit\u003cbr\u003e2001-2002 MZ3 S54: one pipe must be shortened to match factory section 2\u003cbr\u003e2006-2008 Z4M: flanges must be cut and rotated to match the flange orientation of the stock exhaust\u003cbr\u003e\u003cbr\u003eMade in the USA.\u003c\/p\u003e \u003cdiv class=\"allcategories\"\u003e\n\u003cdiv class=\"allcategories_subsection_first\"\u003e\n\u003cbr\u003e\u003cb\u003eBMW Fitments: \u003c\/b\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003e3 Series\u003c\/b\u003e\u003cbr\u003eE46 (99-05) \u0026gt; M3\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eZ Series\u003c\/b\u003e\u003cbr\u003eE36\/7 \/ E36\/8 Z3 (96-02) \u0026gt; Z3 M - S54\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"allcategories_subsection\"\u003e\n\u003cb\u003eZ Series\u003c\/b\u003e\u003cbr\u003eE85 \/ E86 Z4 (03-08) \u0026gt; Z4 M\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BimmerWorld","offers":[{"title":"Default Title","offer_id":43084443877489,"sku":"1004539","price":811.81,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1088\/6742\/files\/media_a17b9362-29fe-4385-93f3-60df9b98479f.jpg?v=1773955098","url":"https:\/\/www.parkautomotorsports.ca\/products\/1004539","provider":"Park Auto Motorsports","version":"1.0","type":"link"}
