Poly mounts should fix that problem. Check the stickies at the top of this forum.

well, i replaced the transmission lastweek.

Let me say it again, as my post was kind of confusing, there is a crossmember between the transmission crossmember, and the rear differential. My exhaust is hitting that piece, and making a noise.

I dont see anything that would hold the exhaust up from hitting this piece. Right now, i just jammed a piece of wood between the exhaust and this crossmember to stop the banging noise.

Sorry if i confuse you.

Take that piece out. Driveshaft loop might be a good replacement for that part.

We call the "crossmember" between the trans crossmember and the rear end the "tunnel brace". I've been running without one for about a year and a half with NOTHING bolted there.

Thumbs up

By an aftermarket tunnel brace - BMR P/N# DTB001 or equilvalent. I paid about $120 bucks for mine. That should give enough clearance to clear the y-pipe. I installed on on my ride a few days ago. See the attachment for the pic.

You can just take it off completely. Free and won't really make a difference. A DS loop is a good way to go and the SLP (others as well) one drops down quite a bit to make room for the exhaust plus gives you a safty feature.

You can also try to make some spacers for your stock one to drop it down if you really want to keep it on there.

Need to know more about the car, exhaust, etc. That brace is actually the driveshaft safety brace. Your exhaust should hang right in between the body, driveshaft, etc. with clearance all around, what has changed on your exhaust?

nothing has changed on the exhaust.

The only thing I can think of was a clip or whatever was loose on the pipe, it looked like this:



anyways, it was ratteling, and i saw it broke off, but i looked at the exhaust, and you could see where it went, and it was just around the pipe, not doing anything, theres another one on there just sitting there, doing nothing.

edit* this clip came off a few months ago, but from what i can remember, the car always made the sound
