Raspy, whats the cause?

[tealsnake93]

So I've had my exhaust set up for about 20K miles and it has slowly started to sound like crap. A real raspiness has developed while running through certian rpm ranges. I have Kooks long tubes, catted H, and a Magnaflow cat-back.

So what is the most likely culprit? Cats? Mufflers?

It still sounds down right pissed off at WOT. Not so much in the mid range.

Not too sure, a friend of mine has long tubes / offroad x pipe / magnaflow cb and it sounds raspy. On the other hand, another one of my buddy's has the stock exhaust manifolds / offroad x pipe / magnaflow cb and it is not raspy at all. It sounds badass as well as pissed off to redline. My guess would be the long tubes. :shrug:

Lose the Maggies. They have a higher note/tone with LT's that I'm not fond of.

Borla Stingers, Mac, Flowmaster Super40/44 or possibly Bassani catbacks would be nice alternatives.

Going to a Prochamber and Borlas would surely fix the rasp ;-)

i would guess the straight through mufflers - if thats what the maggies are
a chambered muffler (flows, MAC etc) would probably not sound as raspy

bassani will be real raspy, cause that's what I got and hate them. I'm just waiting to get a day off so I can get my super 40's welded in.

Thanks for that diagnosis, I hope it's not my londtubes. I guess I'll replace my muflers, and later my cats, and cross my fingers.:shrug:

Yeah, it almost sounds like a leak that comes and goes. Whats perplexing is that it sounded great for a few months, then slowly a horrible note started emerging, now it's overwelming. I absolutely love the sound that I have though, all my chevy friends say "it doesn't even sound like a mustang".

Well I'm almost positive the mufflers have a lifetime warranty, maybe Magnaflow will replace them. Or maybe I'll take my business to another manufacturer.
