Bolt-on power and sound for the FSI!
Over the years 42 has focused on the biggest and baddest race inspired exhaust systems. These systems have fine tuned our fabrication methods and allowed us to test countless materials and components. Along the way we managed to forget one simple fact. Everyone changes their exhaust, but not everyone needs a 3" turbo-back. Our new 2.5" slip fit cat-back is a "back to the basics" system designed for everyone. True slip-on and bolt-up installation requires few tools and no modification. The sound is race-inspired and refined. Best of all, a healthy power increase can be instantly felt. If you're looking to add a simple cat-back exhaust to your Mk5 our 2.5" slip fit system can't be beat!
Our 2.5" slip fit cat-back begins where the factory downpipe ends. A permanent reduction to 2.36" allows 2.5" piping to slide into the factory clamp for a leak-free fit. After the clamp 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 a 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 our 2.5" piping into two without disrupting flow. Hung neatly in the factory exhaust cutout sits a pair of high polished stainless steel tips.
Our exhaust tips are built and polished in-house. We're perfectionists and it's reflected in our tips - literally. Our 2.5" cat-back is 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 our tips are offset to follow the contours of the mk5 rear bumper.
Installation is simple, adjustable, and reliable. A permanent reduction allows use of the stock sleeve clamp. Precise design and fabrication routes 2.5" piping clear of heatshields. Adjustable flanges allow further adjustment if necessary, sealed by a double layer graphite gasket and locking hardware. A pair of collars allow the rear hanger to be locked in place. This means your tips will never slide.
The sound is sporty and refined - not too loud and not a hint of rasp. Instead of telling you all about the sound we would like you to hear it. Extensive sound clips will be added to this webpage shortly.
Pricing starts at $485 and varies by vehicle and tip fitment. Complete 2.5" & 3" turbo-back systems are available for FSI models in additional configurations. All configurations can be purchased ceramic coated.
