This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, we have created a full exhaust system that will provide enough flow to support power levels way above the stock S55. This is a full exhaust system which includes a variant of our single midpipe and does not require a separate midpipe. If you want the unique sound of our equal length midpipe, you should consider our equal length midpipe plus our valved axle back rear exhaust. THIS EXHAUST DOES NOT WORK WITH OUR SINGLE OR EQUAL LENGTH MIDPIPES.

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.

We 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.
