Ok I jus got done tightining my X pipe at the headers. Went out for a test drive down the street...it wasnt leaking at all even after i tightined it once it was warmed up. Going down it was fine...coming back i cracked on it and it opened up like it was leaking real bad before. When I come on the N2O kit...the leak geats 10x worse untill i let off the kit.

Heres my thaught on it....possible passenger side engine mount bad or broke? At idle the car shakes kinda bad just sitting still...like a cammn 5.0. So I watched it from outside with the hood up and it looks like a cammn 5.0 engine shaking....give it some throttle you see the engine twist a little....let off it falls back where it was shaking again.

Inputs please..............

 

How does the car run? Like normal or has some hesitation to it? an 04 with a bad motor mount doesn't seem to possible, but something massed produced, ever so often, one in the batch can be bad. Start it and pop the hood, rev it up at the TB and see if it has tons of play from side to side, should move some but not alot.

 

The car runs fine...like a champ. But I went out a little while ago and got some food and you could notice the leak got worse when i got down on it. Also yes i did the process with the hood up and rev it a little from the TB. It shook alot more than my girls '00 does!
