Two weeks ago I finished by Jet Hot LT install and all was wonderful. I had to let the car sit for a week but when I drove it no rubbing or exhaust noise what so ever.
I drove the car this past weekend (weather was in the 70's)and was showing the new sound off to some of my 4th Gen buddies.
Again no issues.
Then we get snow on monday which is crazy but not very important to this story. I leave the car sit on monday but when Tuesday rolls around I fire the car up to drive it, the weather is nicer but still cold.
I hear this horrendous noise when I ease out of the clutch.
It appears that the exhaust has started hitting some thing but only at low rpm takeoff.

It appears that the A/C compressor line (the one that looks like a long U) directly under the #2 primary is extremely close.

I have to wonder if I broke a motor mount or a tranny mount.
I just find it pretty unlikely that it would be fine one night and then snap on start up two days later.

Any ideas?

 

Sorry but TTT, need to know if anyone else had problems with their LT hitting the condenser(?) line.

 

I'd check the crossmember underneath the car. Mine was touching and made horrible noise/vibrations. Hope this helps you.

 

so what did you do to fix it?
