PERFORMANCE PARTS FOR BMW: ACTIVE AUTOWERKE F87 M2 COMPETITION SIGNATURE EXHAUST SYSTEM INCLUDES ACTIVE F-BRACE (11-051) Product Details: Mandrel bent 304-stainless construction Completely TIG Welded (No MIG Welding at all) Flow efficient Y-Pipe design Perfect fitment with adjustable 90mm double walled tips True 3.5 turbo back design Uses OEM valve motor Designed to be used at stock power levels along with highly modified engines No permanent modifications required Manufactured in house at our facility in Miami, FL. The 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.
