Many people (myself included) have bought and love this system:

42 Draft Designs

You can get reducers to fit your stock DP and you can install it with no modifications. Exact fit for MKIV VWS.

A shop that works with SS would prob charge an arm and a leg to fit that Amazon generic exhaust to your vehicle and fitment may stil stink.

Bah, I am unsure of the VR6 model man, sorry. I "think" it wil bolt up, but may need a little work too.

Edit:

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.

I am unfamiliar with that exhaust as i assume Euro enginuity is that manifature? Magnaflow components are normally a quality piece (this is the muffler brand that 42 DD and others use) but i see that is 2.25in OD piping. so i ask, what is the point? That means ID is probably 2.15" and your stock system is that big...

VR6 has 3" MAF housing while 1.8t is 2.75 I think, I am sure that any silicone provider can get you this piece and a couple band clamps, but I use 034motorsports, BUT ECStuning has this exact one on sale if you don't care about it being stamped with thier name or no name perhaps:

I bought the 3" 42DD catback (magnaflow components), even asked them to leave the flange at the cat side off so I could weld my own v-band flanges.

Depends on the size, but if you grab a 2.75" just get an adapter sleeve and some exhaust clamps from autozone / napa etc. It's easy enough to install yourself with a jack and axle stands.

can't go wrong with 42dd. and you can have them ceramic coat it for efficiency and to prevent rust if you live more north.

support the scene, bro.

You run a VRT though. Really, he should use a different muffler or send/ask 42DD to use a different muffler to compensate for his backpressure. Max he should run is a 2.5, with a Naturally Aspirated higher resistance muffler. Mufflers for turbo cars are practically empty because the turbo and wastegate do all the backpressure work.

I am uneasy about multi engine exhaust systems. Each engine has specific power band requirements.

It looks like it fits though.
