anoying rattling/buzzing sound....
ya my '95 gsr makes this really anoying rattling/buzzing sound at 3k-3600 rpm. im thinking it might be the exhaust system vibrating against the other metal but im not sure cuz its only at 3k-3600 rpm. after that it sounds fine. if anyone has any comments or suggestions it would help

when i first got my car it did the same thing. Turned out to be a piece of heat shield that had cracked and would vibrate at a certain rpm.

I go with the dreaded heat shield problem. After I installed a new header the sound was gone. I also noticed a rattle when I set the stock header on the ground. Looking at it more closely, it was indeed a loose heatshield. It rattled at the simplest tap. I can't confirm for sure that was the problem for me but seems to make sense to me since I didn't see any cracks on the stock header.

This has to be the a-pipe and there is actually an easy fix to this. I had the same problem. The a-pipe is double walled and the inner pipe weld comes loose and causes the inner pipe to vibrate against the outer pipe at 3-3500rpm. The area to target to fix this is about an inch past the bend on the a-pipe. I had a muffler shop burn a hole in the pipe at this piont and then refill with weld material (sauder?). The noise was totally gone. Now...I guess their weld has broken down and the noise is back. I contacted an Acura mechanic and a fix that he uses is to simply take a self tapping metal screw and drill it up into the pipe at this point. I will try that next.
