Exhaust raspy now

Does anyone know the approximate lifespan of an aftermarket muffler? I have a DC HHC5029 header on my 4th gen VTEC (2.5" collector, "JDM Style"), no cat, and an Apexi WS2 catback, and it's gotten really noisy. I've only had the setup for maybe two years, possibly three, and it's not nearly as quiet as it used to be. The resonator on the midpipe is pretty beat up, but I don't see any holes. I it possible that the muffler is toast? That would really suck, cause the price has shot up to almost $700, nearly double what I originally paid.

Re: Exhaust raspy now

I'll definitely have to check that. I'm gonna put it on a friend's lift and have a look at it up close some time soon.

Re: Exhaust raspy now

Check the flex pipe -- mine's rotted out without showing it too much. I've had a WS2 on the car for nearly 10 years, and not a sign of rot in it anywhere.

Re: Exhaust raspy now

Huh. Is it possible the packing inside the muffler has burned out?

It's probably my gaskets. I've had the header apart twice. I wonder how I can get new crush gaskets for the header.

Possible, but I think your problem is upstream.

Re: Exhaust raspy now

Uh.... I think so. Honestly, I haven't been underneath the car in nearly a year, haha. If I remember correctly, it's a Megan Racing resonated test pipe.

Flex pipe x345855243.

If you're lowered at all, this is the weakest part physically and takes a beating, and the metal mesh just gets destroyed, leading to an exhaust leak.
