I have no idea. sometimes I feel like bringing it to the exhaust shop and removing my rear muffler to see if it improves the sound. other times I say this is fine cause I don't want to destroy my stock system , and should live with what I have or get an aftermarket system.
will need tips to do a new Y section for the rear. overall cost would b around 400 ish I assume. debating.....
I'm going to go to a few custom installers (2) and see what they say. Can't hurt to hear their thoughts for sure.
This feels like a stupid question but here goes.... I can't imagine replacing the Downpipe isn't going to void warranty work, right?
Depends on the problem. Remember, it's in the dealership's best interest to not pay, they are going to look for ways to get out of doing no-charge labor. They'd have to show your modification was the cause of the problem (or you'd have to prove it wasn't) - a legal battle you probably don't want to have to engage in. Downpipe changes back pressure and so forth so I could see them trying to not pay for turbo/etc related issues if they occured in the future. This isn't legal advice, I'm not a lawyer, so make sure to do your own reading on law and consumer protection in this regard but I would say it may not be worth the risk of a legal battle if warranty coverage is a concern for you, even if you're eventually found to be correct.
Can you talk a bit more about the neuspeed power module? How difficult was it to install?

WOW.....this car is fast and shifts are much better with less slop feeling. Lower rpm the car is louder with valves open and theres just enough turbo sound that doesn't sound like a wrx (i don't prefer obnoxiously loud bov/diverter valve sounds). I played with 2 cars...a mazdaspeed 3 and 135i and it was laughable how much faster I was just doing some short pulls nothing crazy. This car feels faster than my (manual) M4 was off the line. I saw the S3 got 3.9 0-60, wonder if TT-S would be 3.8 or 3.7 since its lighter weight. I can't imagine what the new TT-RS would be like....Anyways, got the car dialed in now and its a perfect daily drive for such simple and inexpensive mods.
