Anyway to fix it? they welded the hangers on and attached the hangers to some rubber hook things..is there a reason they did that?

bc that's where u put the hangers on. They did that to my car too bc it was movin too.

did they put any hangers on your mufler too??

Mine did that for a few weeks after it was installed. Took 4 or 5 visits before the shop got it right--at no extra charge to me. It can be fixed--you just need to be persistent with the shop. I think they may need to put another hanger on the muffler.

One of my flowmaster hangers broke. Damn that thing clucnked the car everytime I turned, hit a bump, floored the gas, etc. Very annoying after 2-3 days. I took it to another shop and the fixed BOTH hangers for me for $10. No more clankity-clank-clank for me

I need to do that too.

Mines does, i think its better when it has some movement because when you hit bumps or anything the hagers wont break. Try to get new rubber thingis to kee pit from shaking alot.
