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.
