These are pretty bad.. but may give you an idea.. Cold start and on from inside the car..

Sounds good. Still trying to figure out what route I want to go. Been thinking about it for months.

Did it with the shiftek kit. The fitment is eh, and directions weren't extremely clear but I was able to get it installed. I don't like the area with the clamps as there's a large difference in the OD of the pipes, but the clamps seem to seal well. I'd almost want an exhaust shop to weld it up with some intermediate pipe but as long as it stays secure I'll be happy.

Well since I am running a Kooks setup, I have no resonators. Not so bad, and the car sounds great. The Kooks X Pipe is a piece that goes all the way to where the OEM exhaust hooks up. Good quality piece.

Shifteck says their XPipe has 20% more air flow than stock.

What you think about? Only marketing words?

I am unsure if I put the Shifteck in or only pipes from muffler store...

Shifteck installed, wow what a difference. Car is flat out nasty now. I pulled past a couple in a minivan from a stop light and heard a "Jesus Christ!".

PS only issue was I bought this pos, should've just got another sawzall for FL

Not sure about 20% but having installed one on mine, the the sound is now just awesome. Absolutely could not go back to stock. In my mind I think this simple mod really opens up these motors and if Shiftek says 20%, Im apt to take their word for it. Highly recommended.

I just ordered my shifteck, can't wait to get it on this spring. Hope it's quality as the one guy a few posts back said his was not. Although he is the only negative one I have ever read of, and that's with a ton of threads about shifteck. So I guess I won't worry much at this point.
I see most cut off the down piping. Can I ask way and doesn't that make it harder to clamp up? I thought the purpose was so you can slip it in and clamp , wouldn't that make it so you have to weld now once you cut that off ?

I have an appointment scheduled tomorrow to get the resonators cut out and replaced by 3" stainless. They are slip fitting then welding. Does this have any down sides compared to butt welding 2.75"?

Quality of mine was fine. Much louder and pops and backfires even more. I cut off the down pipe - no problem because the factory clamps on that side allow the wider section to butt right in.

Well thanks for the reply.
Just wondering why to even bother with cutting them off? If people are thinking your getting more flow cause of it then I guess , however it must be so minimal it would never even matter anyways and something you would never feel or notice in power or seat of the ass.
I'll probably just leave them be - see no reason to hack a piece that's ready to go. Unless someone can dictate otherwise -------
