I was driving around today, went to school and back...then drove my family to my uncle's place. I thought that my exhaust was getting a little louder, but I wasn't sure if it was just me. Well, on the way back, I stop off to get some gas...everything is normal. I fill up the tank and fire up the engine. It was LOUD!! I idle and everything is fine again. I put it into 1st and it's super LOUD!! like classic muscle car loud. It would stay loud until I let up on the acceleration. I stop the car in front of my house, and I listen as my sister taps the gas. It sounds like it's coming from the B-pipe/cat/Y-pipe flex area. It's hard to tell, but that area is all about 24 inches in length so it's hard to distinguish. I have a feeling it might be the Y-pipe flex section.

here's my exhaust setup:
Stillen 2-piece Y-pipe
Stock cat
Courtesy B-pipe
5th gen muffler

I'm pretty sure that the noise is before the B-pipe, since both the b-pipe and 5th gen have resonators on them. At first, I was afraid that all the glass packs might have been blown on my muffler, but I'm pretty sure it's the Y-pipe. I'll keep you guys updated.

Reach under the car and run your hand a couple inches away from the exhaust and feel of hot air. I'd bet a gasket is leaking from either the cat/y joint or on the two piece Y.

Canuck

I wouldn't be suprised if its the gasket between the Y and the cat, I have had a lot of leaks from there.

Thanks guys for the advice...it turns out that my bolts were incredibly loose. It looks like someone might have tried to steal my muffler. The bolts look like they've been played with a wrench or something. I can't believe some people...just buy your own damn muffler. OK, I'm all better now...just had to vent.
