Everytime my tach hits 1000 rpms(on acceleration only). My exhaust feels like it's about to fall off due to the rattling noise I hear.

As soon as the car hits 1100 rpm's, the rattle is gone. True I might not be down in that rpm range very often, but when I am(my parking garage at work, 5 o' clock traffic etc) it really bugs the **** out of me.

A professional shop put the exhaust on and I saw them tighten every bolt, anyone else have any ideas?? spacers? clearence?

I have the Apex'i World Sport 2 exhaust. Any help appreciated!!

look under to see how the muffler is hanging on? could be loose

What's your idle like? Any rattle when the car is just sitting while running?

If you can, defnately put it up on racks and see where the sound is coming from. Sould just be the exhaust hitting on something

Could it be a heat shield? I replaced my stock cats with the test pipes and left the support bracket off (which holds the cats together). I have no vibration issues or rattling. I hope it's not a stud from your exhaust manifold.

i lifted the car up tonight and didn't see anything out of the ordinary. I'm going to take to the exhaust shop that put it on sat....we'll see...

if anyone else experiences this problem, it's very possible that it's your heatsheild rattling against your muffler.
