Ok I installed my h-pipe and one of teh bolts was loose that connects to the flow tube so i tighten that up so the muffler is no longer hitting the underbody. But I still have this vibration at low RPM's like 4-500 when I'm stopped and the brake is applied. If I brake tork it a little bit up to like 700 rpm's its fine but down low its vibrates like crazy. What the hell could this be? Do you guys think that somewhere the pipe is touching the body causing it to vibrate or is it in the motor because of the cats being gone? What do you guys idle at when stopped at a Stoplight?

sounds like your exhaust is hitting somewhere. mine used to do that becauseBluThnder99 said:
the shop that installed my headers used the wrong x pipe and the cats were
hitting the crossmember.

you know where your tail pipes after the mufflers bend up over the rear axles? check and see if either of them are touching the frame. that will cause what you are describing, especially on the low rpms.

other than that, your mid pipe could be hitting somewhere on the frame, check the o2 wires, they can make some serious noise if not secured.
