I have been chasing down this noise in my exhaust system for a few years. The noise is hard to explain, but if you have ever heard the rattle from an old exhaust shield vibration before it lets go, that's what it sounds like. The rattle only shows up under hard acceleration about 4 or 5 thousand rpm and it stops within 2 seconds of hearing it. I'm running the mrt catted h pipe and I'm wondering if anyone has run into issues with cat shields vibrating like this, even when the spot welds look good?
Like I say, the noise has been there for a few summers, the catback and headers have been replaced so the midpipe is the only consistent piece with the noise. I'm thinking of cutting the shields off the cats, will they come right off after drilling the spot welds? Will I have to worry about heat if I do remove them?
