Motor Mounts
 

Just wondering if this is my possible situation:

October last year, finally got the new motor running, and driveable. But, with any high demand situation on the motor (read fast acceleration/deep throttle) the Y-Pipe now bangs against the floor. This never happened before. Upon further inspection, the Y-Pipe (ASM headers BTW) appears to be actually angled upwards a little. Odd I think.

The stock motor mounts were NOT replaced, and have 108K miles on them. Any chance that these are sagging enough, and when I get into the gas the motor is raising a bit causing the y-pipe to come into contact with the floor pan??

If it sounds feasible, I'm going to order a set of E.S. poly mounts.

that is most likely what is going on. i would say they are prolly broken, not jsut sagging.
get teh poly's in there and let us know how it is.

later

ya definatly the mounts they should always be replaced during a swap
