redwake I totally missed the part where this was an mk3... thats what happens when i just scroll through the new posts vs going thourgh the forum.

VH5150 is right.

Suggest low and slow until parts start showing up in a couple-few years. Right now the after market crew isn't doing jack for the MK3 unless it says ST on your front grille.

Keep bugging SCT.

Gonna call Shenanigans here--until somebody comes out with a tune for these cars, there's not much sense in "prepping your car for a turbo". SCT was probably our best hope for a tuner for the '12+, and it sounds like they've given-up on it.

Your going to want to run 2.5 or 3" for the turbo any ways so i wouldn't invest any more time on our exhaust other than what you have already done until your ready to bump up the tubing size.
Thats what I was thinking too. Why mess w/ that s^%$. I'd be figuring out the turbo, bv, boost controler's ect. How 'bout a clutch or a torsen or quaife & your suspension?

StingRay Back pressure is a myth, just FYI

But like others said if you are going to do a Turbo setup soon, I wouldn't worry too much about your current exhaust. Just cut the other muffler and keep the same size piping.

JL330 Without going to bigger piping it won't really change much.

BaconZombie Deleting both mufflers and the resonator will result in an obnoxiously loud exhaust. Someone on here had posted a video of their car without any muffling pieces on it. It was loud. I started my car up when I had everything behind the cat removed, and while it was very loud, it didn't sound horrible, but for a daily driver is was far more than I can handle. Several of us have gone with either brand-name or custom-made exhausts with just 1 muffler and are quite happy with the sound and power gains. Check out my videos, Redfocz...I know there's more, just look around.

I'll side-step addressing any turbo related exhaust info and just answer the core question.

If you want loud and absolutely obnoxious, then you'll want to get rid of the resonator and first muffler. If you are keeping the piping diameter stock size, you won't run into back-pressure issues.

As you and matmatician alluded to, the pre-cat in the exhaust manifold (and a second cat if you have one) will provide enough restriction.

Jkrumm I am more engine and mechanical than exhaust and body but i love the sound of a nice loud car
12-03-2012 09:06 PM
matmatician Exactly. The cats are the main choke points, so I don't imagine you'd lose a significant amount of back pressure.. But again, I'm not really an exhaust guy :P
