cold start, same set-up:

Thought I would share this here; Same car as above: Fast Intensions system with modified real burnt titanium quad tips. I just finished the install:tiphat:

Nice setup.....sounds good. Not liking the hissing noise.

once you change the HFC.... you'll have that hissss no matter what.....
me personally, I love it! u cant really hear it from inside, but I tell ya the people outside break their necks looking and wondering WTF is going on under that hood lmao:driving:

My test pipes are as loud as my BPV from my last car.

oh yes. every cars and coffee meet or any meet I go to, I will look over and see people with their head buried in engine bay or under my car looking for turbos lol :bowrofl:

Then they are clueless because the turbo is a hell of a muffler and actually makes less noise but you wouldn't know since NA:stirthepot:

Man I want to get this exhaust but I'm almost sure I'll get twins in the future.

By twins, you mean turbos? Cuz that wouldn't stop you from getting this exhaust

I thought when you get twins, you need a custom exhaust? I may sound ignorant asking this but hey, if you're about to tell me I can buy the exhaust then I don't mind looking foolish.

aside from the fact that I am NA, I do know and understand all the aspects of boost my friend :tiphat:

turbos basically act like a set of mufflers.

if you want loud exhaust and good flow for more power you'll basically want to go with 3" straight pipes with twins. power and sound. that is my plan if/when I go with boost.

Well FI makes a TT kit and their exhaust bolts up to it. Any TT kit that keeps the stock triangle header flange location is going to mate up to this exhaust.

Buy the exhaust!

You know trolling you is how I make it thru the work day :tup:
