Default What could it be?

Two day's ago, I installed the GTA muffler's off the Shelby GT on my car. Everything was fine (I would believe) until I took in my car yesterday to install CATS (I didn't have any before). Anyways, long story short, my car rattles like crazy on the right passanger side. Is that from the CATS? Improper installation? I doubt it's the muffler's since they are barely any louder than the GT Take off's. Anyways my set up is this:

MAC Long Tube Headers
Eastern Hi-Flow CATS
MAC O/R H-Pipe
FRPP GTA's

and yes, the car is a 6 (and dont tell me that is the problem or my fist will go through my monitor and right into your face hahaha)

you drive a 6 that is the problem

On a serious note check the hangers on the mufflers, these can rub sometimes

I took the right exhaust off and put it back. Throughly checked what could be wrong and found nothing. It comes from the side passanger area, near the front. It's like a vibrating sound. The left one is fine and doesnt make any noise. Argh this is angering me to no end haha.

Check the connection of the mid-pipe with the headers.

Take it back to the shop that did the install and tell them the problem. They should be able to adjust something....

I had the same issue when I put on my duals. it turned out to be one of the fasteners on the band clamps that connected my xpipe to the midpipes were just barely touching the body of the car so when I would drive it you would get a rattle that would drive me crazy at certain RPM's. A little gentle persuasion and all is right with the world now. Check for any signs of rubbing or contact with the body in any way.
