Solid and honest gains Manufactured from T304 aircraft quality stainless steel with mandrel-bent 3" diameter tubing and polished to a mirror shine. This High Flow Cat has proven a solid 16HP & 19lb-ft Torque @ 4600RPM to the WHEELS on the dynamometer. The factory cat is extremely restrictive, and by just replacing it with this bolt on HPipe which goes in-line with your factory or aftermarket exhaust system, you will unleash the hidden potential of your 2.0TSI motor not to mention quicker spool up of the turbo.

Our High Flow Cat "HPipe" starts off at the back of the turbo with a 3.5" ID. We have used a 3.5" cat instead of a 3" cat for a greater flow characteristic. After the cat the, it transitions to 3" ID down at the factory downpipe flange. We did this because the OEM gasket between the turbo and cat only has an ID of 3.5", and going any lager wouldn't be of any benefit. This unit will work with all after market as well as OEM exhaust systems that utilize the factory flange and adaptor location. Choose from our Hpipe or Hpipe with new OEM gaskets and installation hardware.
