Bimmerworld E9X Street Cat-Back Exhaust
Selling my Bimmerworld E9X Street Exhaust with quad 3.5" tips which is now discontinued, but used to be made for them by Magnaflow and sold for $1,400-1,700 new. Will post a picture of it on my E90 M3, but following link has good pictures and video on an E92 M3. https://www.m3post.com/forums/showthread.php?t=1401409 - Still on my car if you want to see/listen. - Asking $750 + shipping or free pickup in Atlanta Their description: Our BimmerWorld E9X M3 Axle*Back Exhaust should be a required option for all E9X M3 enthusiast owners. The S65 V8 engine sounds amazing in race trim * the natural sound of a high*-revving, short*stroke V8 is unmistakable. It's a shame that, in order to sell a street car to a broad market, that sound gets stifled by a chambered muffler that produces excessive backpressure and an overly muffled, synthetic*sounding tone. This type of muffler gets its name from the "chambers" that are formed by various perforated bulkheads designed to slow and control the sound waves of the exhaust flow, eliminating latent noise not absorbed by the factory resonators. At the heart of the BimmerWorld E9X M3 Axle*Back Exhaust is an open-*flow muffler with a unique perforated "S-*pipe." Unlike the factory baffles that slam the door in the face of exiting exhaust gasses, the added weight and clutter of J*-tubes used by some aftermarket systems, or straight through racing mufflers which eliminate restrictions but are obnoxious for a street car, our S*-pipe design disrupts sound waves while still maintaining a smooth, flowing path for exhaust to exit unrestricted.Wrapped with stainless steel wool, the perforated S*pipe creates a smooth and refined tone under moderate throttle application and typical highway cruising without the intense level of exhaust drone found in other "performance" exhausts. Aside from just weight savings and the power increase, the biggest plus is that our exhaust opens up to an intoxicatingly aggressive and natural uncorked engine note when you drop the hammer. BimmerWorld worked in tandem with our manufacturer's engineering team to put together the right all*-stainless, mandrel* bent tube and muffler package to achieve a horsepower* boosting, sound enhancing, lightweight package that truly belongs bolted to the back of BMW's most impressive high-*revving V8 engine. Technical Features -S-*pipe muffler design for open exhaust flow and increased power -Fits stock and aftermarket mid sections, including BimmerWorld Street and Race X-*Pipes -Mandrel bent tubing for smooth flow and long term durability -All 304 stainless steel construction, weighing just 41 lbs * a full 15 pounds less than stock! -Quad 3.5" chrome* plated twin* wall stainless tips that will hold up beautifully to exhaust *soot and cleaning over time Last edited by JPS-ATL; 12-10-2019 at 09:47 AM.. |
