RAI Motorsport Mk6 3" Downpipe Group Buy!!! You'll want to get in on this!

I am stage 2, I just got it without the testpipe file. I also want to add that while under heavy throttle I notice a loud air turbulence sound coming from towards the rear. At first I thought it was a rattle but the more I listen it does not sound metallic. It doesn't matter what RPMs or speed I am at, just when I lay on the pedal. Is this just added noise from the downpipe with stock catback or something else?

That's just the larger amount of air (due to the downpipe) now being rushed thru a smaller restrictive exhaust (the OEM cat-back)

Downpipe + stock cat-back = Stage 2 power, but not so great sound

You gotta switch out the cat-back if you don't like what you hear

Thanks, that was what I was figuring. Time to start saving some cash again lol.
