VW Mk5 2.0T FSI/TSI
2.5" & 3" Cat-back Exhaust

All out power and sound for the FSI!

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" FSI/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 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 our 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 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 our tips are offset to follow the contours of the mk5 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.

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.

Pricing starts at $485 and varies by vehicle, pipe size and tip fitment. Complete 2.5" & 3" turbo-back systems are available for FSI/TSI models in additional configurations. All configurations can be purchased ceramic coated.

Important Fitment Information
Please Read BEFORE Purchasing

Our mk5 2.5" & 3" cat-back systems are specifically designed:

  • to bolt-up to our FSI/TSI 3" downpipes
  • as the rear portion of our FSI 2.5" & 3" turbo-backs
  • to be custom fit to a 3" FSI/TSI downpipe
  • to be used on heavily modified vehicles

Our mk5 2.5" & 3" cat-back systems are NOT designed:

  • to connect to a stock FSI/TSI downpipe
  • to connect to a stock 2.5L downpipe
  • to fit any vehicle other than a mk5 FWD chassis
  • to provide astronomical gains on a stock motor

Fitment to our FSI/TSI 3" downpipes or as part of our turbo-back systems is as easy as we describe. Fitment to a 3" downpipe not built by 42 requires welding of a 3" flange to the existing 3" downpipe at the correct location, angle, and rotation. Successful fitment of our flanged 2.5" or 3" cat-back in custom applications is the responsibility of the owner. Fitment of our 2.5" or 3" cat-back to any stock downpipe or downpipe under 2.5" or 3" in diameter respectively is not recommended by 42 and cannot be supported. There are reasons why we make specific recommendations.

If you're interested in a full turbo-back exhaust, we offer systems for the FSI/TSI which combine these cat-backs with our 3" downpipes. Check them out! FSI/TSI 3" Turbo-back Systems

Power Gains

Power gains cannot be definitively stated for this system. Every single installation is different. Power gains related to this system depend entirely on what's in front of it. FSI/TSI engines with complimenting mods and a 3" downpipe will see typical 3" turbo-back gains. An FSI with a GT30 turbo and a 3" downpipe is going to see maximum power at whatever boost level their motor can support.

Please Note
42's cat-backs are manufactured from scratch in Millersville, MD. We use high quality American made materials throughout our exhaust systems, manufacturing in-house every component possible. When necessary to outsource, American companies are chosen who manufacture their products in the USA. Our systems are built in our 4000 sq/ft facility by a team of 7 machinists, fabricators, and TIG welders trained to complete each system with exacting precision. Our TIG welders take their time, welding each joint with care. From design to manufacturing we never rush, cut corners, or take shortcuts. If you have any questions, concerns, or comments about our cat-backs please contact us by email: sales@42draftdesigns.com or telephone: 410.923.0411. Our telephone rings in the same building our systems are created. We are here to help.
