All out power and sound for the TSI!

Turbocharged horsepower requires serious exhaust. Maximum power starts with a big downpipe and ends with an equally free flowing exhaust system. Designed to bolt to our 3" TSI downpipes, our 2.5" & 3" cat-backs pick up where the downpipe leaves off. The result is honest performance that sounds and looks as great as it feels.

Our 2.5" and 3" cat-backs begin where our 3" downpipe ends. A CNC machined flange attaches to the final downpipe flange with locking hardware and a double layer graphite gasket. After the flange a set of hangers slide into the factory hanger bushings and supports the piping as it bends into a Magnaflow muffler. After the muffler a short bend ends at another CNC machined flange. This flange connection is adjustable allowing precise fitment of the tips. Piping leaves the flanges and routes neatly under the rear suspension. A precisely fabricated merge evenly divides our piping without disrupting flow. Hung neatly in the factory exhaust cutouts, a pair of high polished stainless steel tips complete the system.

During our initial design work we discovered quickly that the Mk6 rear valance requires a unique pair of exhaust tips. The contours of the rear valance easily overpower the tips. In order for a set of tips to stand out they must be large. We experimented with 4" tips in multiple styles but we were never satisfied with the fitment. Honestly, they looked ridiculous. We decided to blend in instead of stand out, starting from scratch with 3.5" diameter material. 3.5" is powerful enough to be noticed but subtle enough to let the contours of the rear valance take over. Our final exhaust tip design truly compliments the rear valance of the Mk6 GTI.

Installation of our cat-back system is simple, adjustable, and reliable. A permanent flange allows the system to bolt to our 3" downpipe. Precise design and fabrication routes piping clear of heatshields. Adjustable flanges allow further adjustment if necessary, sealed by double layer graphite gaskets and locking hardware. A pair of collars on each rear hanger lock the tips in place.

The sound is sporty and refined - not too loud and not a hint of rasp. Because sound varies based on downpipe configuration we cannot accurately describe the resulting sound with words alone. Extensive sound clips will be added to this webpage shortly. These sound clips will present the 2.5" and 3" systems in a variety of turbo-back configurations.
