I don't mind a bit of rasp... but mine is much more than just a bit.

My car sounded worse than a civic but only under WOT or when I was "getting on it". NO- THE RASP WAS NOT CAUSED BY AN EXHAUST LEAK.

So I decided the stock muffler wasn't tuned to handle the increased air flow and higher rate of exhaust. I purchased the TSE3, knowing it would be loud but hopefully it will uniform this sound. Wow- it sounded great....until I "got on it" and then it would be raspy... a more intentional sounding raspy (if that makes sense) but still sound unrealistically loud. Not NEARLY as shitty sounding as it was with the stock exhaust.

Then I said WTF and ordered two magnaflow high flow cats and had them thrown in. Overall the car sounds a little lower pitch and the raspy is still at WOT but not the cheap ass sound, probably "just the sound they make". But I'll tell you what, it's a night and day difference now than what it was running a catless system on stock exhaust.... almost $2500 dollars later.
I'm sorry to hear about this and honestly, that is exactly what I am worried about. I think I will be getting a rogue Ikon exhaust in the near future and will go from there but honestly, as long as the tone improves I will be ok.

I would suggest that once your engine has cooled, run it again for about 5 minutes until it is just barely hot again and then start checking your bolts to make sure they are all tight. as well all know, metal expands in heat so once you let the engine warm up just a tad, it should expand enough to where if the bolts can be tightened, they will. so just check to make sure they are all tight. i would suggest to start with the top bolts and then check the lower ones. but after you turn your car off, just go inside and get a drink or something to waste a few minutes, then check them, otherwise you will just burn yourself.

good luck.
I still need to retighten all my bolts, I will try to get that done this weekend!
