I just finally fixed my exhaust leak finally, still some small leaks but nothing like originally. I had switched to a Flowmaster X pipe and Outlaw axle backs and had to get new exhaust clamps since I bent the stock ones on removal from the cats. I was wondering if anyone else has found that after market x or h pipes have caused much more vibration then the stock h-pipe. I only ask because I seem to be getting a lot of vibration now. I know that our cars have no undercoating and very little sound/vibration deadening and so I am fine with the vibration, rather like the feel, kind of like a real race car. The only thing I am wondering is if anyone else has a similar feel after swapping or if it is possible that some of the exhaust is resting on the frame which is translating all the vibration.

 

If you kept the sidepipes, make sure they are angled down away from the floor.

 

I had removed them, however I realized right when I got up underneath the car that I had tightened one of the clamps down and the bolt was touching the frame, now I feel like a tard.
