i installed my OEM exhaust back on and its making a rattling tin can noise (like a small rock) inside my muffler/axel back. when i look through the canister, its just a straight pipe with a honey comb style muffler deep inside and it looks like i wont be able to remove the small object by shaking it off. i would like to know what can i do about this?
the rattling happens during idle (where its real loud at most) and at 2k rpm

are u sure its your muffler, because some time back i had the problem with my car, but i turned out to be my something else (heatshield)

here is someone else that might have had the same prob

heat shield eh? ill definately check that out.




update: i took a better look and turns out the springs that sit inbetween the axel back and mid pipe were loose. and to think of it, i might have took the springs/bolts from my OEM rsx muffler which is shorter than the civic ones.

to find out if its a heatshield put fyour foot on the muffler while its running and apply preassure in any direction. the sound willl either get quieter or louder if it was a heatshield

and if its the heatshield... use a screwdriver to just bend it a little and it will stop..

theres better ways of doing it.. but that way works the fastest
