Bah, I am unsure of the VR6 model man, sorry. I "think" it wil bolt up, but may need a little work too.
says this on the site: While all of our long-term testing was done on 1.8T vehicles, this system will also fit turbocharged 2.0, VR6, and even TDI equipped mk4 VWs. Fitment is designed to connect to your existing 3" downpipe. The system will bolt-up perfectly to our 1.8T 3" downpipes, but we also accomodate other brands of 3" downpipes and custom downpipes by including an extra flange. This flange is intended to be welded to the end of your existing 3" downpipe. Precise fitment of our flange to your existing downpipe is necessary in order to fit this cat-back correctly. While this may seem like a hassle, it is necessary for us to assure a perfect fit. Keep in mind, these cat-backs are designed for factory and custom turbocharged vehicles (1.8T, 2.0T, VR6T). 3" piping is beyond overkill for all-motor applications and not recommended by 42. Our flanged system is designed to bolt-up to our 1.8T 3" downpipes and allow custom fitment to any 3" downpipe on any motor.
