hey, im a noob here, just bought an 06 gto, im wondering if the car has an aftermarket exhaust on it, its alittle louder than "others" or i may bee crazzy,
But the car has 4" tips on it, wondering what size the "stock" ones are? the mufflers dont have a name on them, but its stainless. thanks, mike

Welcome to the site.

4" is the O/D of the tips. . . . . . . . ? Is it a thick walled tip that has a rolled lip?

Post some pics and we will tell you quickly what you have.

I like the sound of the 06's. I think if someone did headers and removed the cats that thing would sound pretty nasty.

They do!

It depends on the sound you like. I prefer the SpinTech ProStreet's or the Magnaflow Bullet Race Muffler's. I personally hate the resonating systems that do all that popping like a pair of glass packs from 1977.

I heard some clips of spintech's and they are sick sounding. I like those quite a bit too. I just think for a stock system the 06 is a pretty tough sounding exhaust to be bone stock. My bro took off out of here the other day and if I didn't know any better I'd say it was an aftermarket catback on it. I did notice the crackle in it but it wasn't overbearing I didn't think.

I agree the stock 06 exaust has a great tone.

+1... I was next to a new 'vette last night at a stop light. He got the green first for a left turn, and I stuck my head out to listen to the exhaust and....nothing. I couldnt hear even a whisper off the vette over my GTO at idle. When he goosed it on the straightaway between some tall buildings, still nothing. The 06 GTO exhaust is nuts...

Heres a vid of my stock exhaust I took with my digital camera...RPMs never went above 3500
