42 Draft Designs - Audi A3 2.0t FSI / TSI - Flanged 2.5" cat back exhaust

42 Draft Designs

Designed to bolt to the 42 Draft 3" FSI/TSI downpipes, these 2.5" cat-backs pick up where the downpipe leaves off. The result is honest performance that sounds and looks as great as it feels. Will not fit stock or other brand downpipes without modification.

The 2.5" cat-back begin where the 42 Draft Designs 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 supported by an additional hanger. 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 splits the piping into two without disrupting flow. Hung neatly in the factory exhaust cutout sits a pair of high polished stainless steel tips.

42 Draft's exhaust tips are built and polished in-house. The 42 Draft cat-backs are available with the choice of single wall or double wall tips. Single wall tips are constructed from a single 3" tube. Each tip is angle cut and welded to a press-formed expansion then polished to a mirror finish outside and shined-up inside. Double wall tips are constructed from two tubes - an inner barrel and an outer barrel. The inner barrel is angle cut and press-formed to precisely meet the angle cut 3" outer barrel. Welding, smoothing and polishing gives these tips a powerful look up-close and from a distance. In either construction the tips are offset to follow the contours of the Audi A3 rear bumper.

Installation 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 allow the rear hanger to be locked in place. This means your tips will never slide.
