Constructed of 100% 304 TIG welded stainless steel, we have created a modular exhaust system that will provide enough flow to support power levels way above the stock S55.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe stock S55 Midpipe is a dual pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5\" pipe directly after the downpipes, our system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.\u003cbr\u003e \u003cbr\u003eWe believe that we've built the best performing exhaust on the market. With the reduced back pressure and large single-pipe design you can expect exhaust velocity to remain as high as possible throughout the entire system. Our design is also capable of handling much higher power levels than stock. It's over engineered to have no issues handling the increased exhaust volume from extensive modifications including turbo upgrades. All Active Autowerke exhausts are designed and manufactured for performance, and our S55 exhaust is no different. Instead of copying the OEM exhaust, we started with a blank canvas in order to create a system as close to perfect as possible.\u003cbr\u003e  \u003cbr\u003eMADE IN THE USA\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pagebuilder-column-group\" data-background-images=\"{}\" data-content-type=\"column-group\" data-appearance=\"default\" data-grid-size=\"12\" data-element=\"main\" data-pb-style=\"LTT6J5A\"\u003e\n\u003cdiv class=\"pagebuilder-column-line\" data-content-type=\"column-line\" data-element=\"main\" data-pb-style=\"EEQ7PUC\"\u003e\n\u003cdiv class=\"pagebuilder-column\" data-content-type=\"column\" data-appearance=\"full-height\" data-background-images=\"{}\" data-element=\"main\" data-pb-style=\"C1HHF6C\"\u003e\n\u003ch2 data-content-type=\"heading\" data-appearance=\"default\" data-element=\"main\"\u003eKEY FEATURES\u003c\/h2\u003e\n\u003cdiv data-content-type=\"text\" data-appearance=\"default\" data-element=\"main\"\u003e\n\u003cul\u003e\n\u003cli\u003e Mandrel bent 304-stainless construction\u003c\/li\u003e\n\u003cli\u003eCompletely TIG Welded (No MIG Welding at all)\u003c\/li\u003e\n\u003cli\u003eFlow efficient Y-Pipe design\u003c\/li\u003e\n\u003cli\u003ePerfect fitment with adjustable 90mm double walled tips\u003c\/li\u003e\n\u003cli\u003eTrue 3.5u201d turbo back design\u003c\/li\u003e\n\u003cli\u003eUses OEM valve motor\u003c\/li\u003e\n\u003cli\u003eDesigned to be used at stock power levels along with highly modified engines\u003c\/li\u003e\n\u003cli\u003eNo permanent modifications required\u003c\/li\u003e\n\u003cli\u003eManufactured in house at our facility in Miami, FL.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pagebuilder-column\" data-content-type=\"column\" data-appearance=\"full-height\" data-background-images=\"{}\" data-element=\"main\" data-pb-style=\"V7XXULY\"\u003e\n\u003ch2 data-content-type=\"heading\" data-appearance=\"default\" data-element=\"main\"\u003eAPPLICATIONS\u003c\/h2\u003e\n\u003cdiv data-content-type=\"text\" data-appearance=\"default\" data-element=\"main\"\u003e\n\u003cul\u003e\n\u003cli\u003e 2014+ M3 \/ M4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"AUTOPERFORMANCE.DK","offers":[{"title":"Brushed Silver","offer_id":50974424760657,"sku":"","price":34095.0,"currency_code":"DKK","in_stock":true},{"title":"Matte Black","offer_id":50974424793425,"sku":"","price":34395.0,"currency_code":"DKK","in_stock":true},{"title":"Carbon","offer_id":50974424826193,"sku":"","price":37395.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/3500\/4497\/files\/10_2048x_ba176307-6693-46b2-877c-03c7bbe15dfc.jpg?v=1744889218","url":"https:\/\/autoperformance.dk\/sv\/products\/f8x-m3-m4-signature-exhaust-system","provider":"AUTOPERFORMANCE.DK","version":"1.0","type":"link"}
