Has anyone ever had a loud ratteling problem with a greddy evo2 catback. I have a 2004 honda civic getting a really high pitched rattle. Went back and tightened everything and check for anything that could and there is nothing. Im pretty sure it is coming from the muffler itself.

negative, ive had mine for almost two years and still sounds awesome

well this sucks then!!! its been doing it for about a month now and dont know what to do about it pretty close to putting my stock muffler back on thats how horrible this noise is.

when does it make the noise? at idle, when you accelerate or when? Also, are you sure its your muffler? There have been lots of problems with the EVO2 and the heat shield, i had the problem.

its pretty much all the time. I checked the shield and tried bending it away from anything and still have the same problem. What sheild did u have problems with.

check your hangers, also make sure your muffler isnt hitting the bumper. wait for your car to cool, climb down, and give your exhaust a good shake, listen for a noise.

waiting for it to cool is for pansies

your right...go balls out....grab that sucker

Well a rattle is easy to fix, so dont give up, as the guys said before get down there and check it out, pull the heat shields if you have to, check the bumper, and check all the hangers, they slide into a rubber boot, if all else fails spray so WD40 on the rubbers and see if that helps....I have had mine for three years and never had a problem. However i did loose a hanger once and it was rattling some but dont give it up yet, rember how ****ty stock exhaust sounds!

sorry guys but i have done all the stuff u posted still no results. Thats why im leaning towards it is something inside the muffler that is moving or somthing like that.

alright guys i took my car to my uncles garage got it up on racks and got underneath the car. I took every heat shield off the car went over all the bolts to make sure they were tight and still getting the rattle anymore ideas?

make sure it isn't hitting on the underside of the car above the lower control arm. mine used to rattle on the frame at that upper bend.

figured out what it was!! it was my resonator had to get it taken off and a straight peice of pipe welded on.
