Default help with Y pipe beating the **** out of my car

i went from a TD setup to an ory and catback. i love it except my ory is beating the hell out of the bottom of my car right under my feet. i can see where its hitting and i use a flat bar to pry it down but when im accelerating but once i get to speed, idle, or WOT, it stops... any ideas of how to fix this.. it gets annoying as hell

Im using this, it works from time to time. I think i just need to mess with it a bit more to get it to completely stop the banging.

Other guy's solve this problem by getting new motor mounts installed.

I had the same problem and I have the pacesetter headers/y-pipe combo which I hear are about the worst because they fit so closely against the car.

I've done the heater hose thing and it stopped the banging but it created a vibration.

I took it back to the shop that installed it and they loosened the clamps and used a pry bar to pull it away from the car where it bangs and then retightened the clamps. So far it has worked fine.

Get a friend and have him push with his legs under the car to where it's not hitting. Take a really good bunjee cord and wrap it around the hanger or somewhere that it don't get hot and call it a day. Sure it's a rig job but it works great. Mine did this with the duals and it was hitting under the pass seat. Never hit again after I installed it. Just don't tell anyone. lol Mine did stop banging after getting new motor mounts but I only did that cause I had to replace the engine.

I went to Autozone, picked up a foot of heater hose, and used a clamp throught the hose to secure it between the y-pipe and floorpan. I got my inspiration from bobbyd's post right here

Mark on the y-pipe where its hitting and then take it off the car (if its not welded) and bang a dent in it with a hammer to give it some clearance.

hose or mufflex bracket is a band-aid for a bigger problem.

free way would be to clearance it with a "dent" which works well.

but the best way is to install poly motor mounts. i did that and now run my exhaust 1/4" from my frame and never have banging.

do it right

You can cobble together something as a remedy or you can solve the problem as the included posts suggest.

Upgrade your motor mounts to either Poly's or Solids. It's a PITA, but there is a really great write-up on here you can follow and you'll be glad you did it once you've finished.

Here's the writeup. Good luck, man.
