Well "it" is my exhaust....i didn't think that it would effect my motor or anything but that first shop i took it to to get my exhaust fixed said that how my exhaust is is really hurting my motor..i thought he was just trying to scare me into getting it fixed there for 450 bucks. But today i noticed she's not running well at all...i first noticed it this morning at a stoplight bein generous with my right foot...it seemed like it was missing. Then on my way home from work getting on the interstate under half accelleration it did it again. I'm getting my exhaust done this weekend(i finally have the money again) and if it's still doign it i'll try my MAF sensor, is there anything else it could be? is my exhaust REALLY hurting my motor? any input would be great...

What do you mean by exhaust? There is alot from the exhaust manifolds all the way back to the tips. I suppose the guy is talking about the CAT and possibly the Ubend.

Um, for $450, you could order an aftermarket exhaust. I'd get another price quote, that's too high, even for a custom job. What is wrong with the exhaust?

well my exhuast is apparently custom...its just a 3 inch pipe from the cat back, no u-bend, but its rusting off and has rust holes all throughout it...then it goes to the stock y-pipe, thats what he said was hurting it because it's "choking" the motor and he said it was bad to not have a u-bend :rolleyes: ...the problem is just when i get on it it stutters...its done it before and was the MAF, i just cleaned it so i may be in need of another cleaning i hope...

Unless the stock "y" has a cat sleeping in it, then that isn't a problem. It could just be leaking there, and that would just make it loud. I would run new with a new cat and 2.5-3" back with a new y pipe and do as you want with keeping or replacing the mufflers.

Your car will not stumble with an open exhaust. I briefly did test runs with my car with a glasspack slapped on after the headers. It ran fine. Rusting through of the exhaust makes it louder, it doesn't cause running issues unless there is a blockage. Look for your problem elsewhere.

if that guy said not having a u-bend was a bad thing, it's obvious that he didn't know what he was talking about.
steer clear of that shop.
btw... I had my catback fully custom fabricated for $230, so the price they quoted you is a rip off
