Product Description
GruvenParts.com is proud to release this 304 Stainless high flow cat pipe for the VW MKIV R32 and MK1 Audi TT with the 3.2L VR6 motor. This high flow cat pipe comes ready to install and bolts directly to the OEM down pipe. This pipe increases torque and horsepower in the mid and high range of the powerband by eliminating the restrictive factory cat pipe.
This pipe is precision mandrel bent from T304L stainless steel so it has no crimps and will not rust. The twin pipes are 2" diameter and are merged with a 2.5" single outflow pipe with smooth transitions for free flowing exhaust pulses. This pipe comes as shown with 2 brand new Magnaflow spun metallic 200 cell cats , 2 OEM gaskets, and all installation hardware. And, its made right here in the USA !
This pipe fits all Audi TT MK1 w/3.2L VR6 motor as well as VW MKIV R32.

MK4 R32 CATS
Posted by Joshua Lee Hawkins on 12th Mar 2021
Great product. Fast shipping. I can't be any happier, it was the perfect length, gaskets, and new hardware. What more could you ask for. Will be coming back for more quality parts from Gruven.

Very nice

I put this on my mk4 R32 and I can say that is a very nicely put together piece. The welds are very clean and solid, and everything fit perfectly.
The car sounds amazing with it on too which is always a bonus.

'04 R32...Extremely happy and impressed with the quality, welds, fitment, and SOUND
Posted by Nik Keller on 12th Jun 2017
As a senior technician and mechanic at a local Euro Specialist/Repair Shop, I've seen plenty of poor-quality aftermarket parts...which is the sole reason I've been reluctant to "tinker" with my personal driver and love (mostly stock MKIV R with 60K miles, and owned since new). With the cat-back I recently installed, this high flow cat pipe made the sound I wanted. Raw VR6 without being too much...LOVE IT
