i have had my apexi ws cat-back on my for about 2.5-3 years. when i first put it on i noticed that the car raddled alittle from the cat-back. well now the car raddles and shakes alittle when im in rev or at idle w/o brake on.
does anyone else have this problem?
i just want to pin point the cause of the raddle.

 

does ur shifter hit the piping at all?

 

its a auto.

 

could be that one of the heat shields under there are loose, get under there and check it out

 

yeah i will. i thought that i got all them out of there when we installed it. but yeah thanks i will check out the underside.

 

i have 2.25 piping too. the rear section of it near the muffler rattles against the underside of the car. i don't know what it's hitting though. it gets annoying at times but i deal with it.

 

all my heat shields are out, and mine still rattles a little bit. i can only notice it at idle. how bad is it? i suppose if you were really dedicated, you find out where exactly it is rattling, then put some heat wrap over it to pad it.

it really has nothing to do with being dedicated or not. the piping was made wider. therefore it rattles once in a while. not a major problem to me. it only rattles at idle once in a while.

 

Sometimes it's just a little adjustment of the hangers that could cure it.

On my Miata the Jackson Racing cat back has hangers that are right angle rods that go through the rubber hangers. So the whole exhaust can "creep" over to the right in time and start to rub on the body.

I went under there and put hose clamps on the rods that keep it from moving around. Problem solved.
