I added a flowmaster catback about 2 weeks ago. When the car is in park and you rev the car is it supposed to move a lot or is that not normal?
Its a 96 z28. I rev the car and it moves forward. Or is it that the Z has some major *****?

 

It moves in park when you rev it? No thats not normal...if it moves in park its either not catching park at all or its still holding a gear which wouldn't make much sense.

 

OK well it doesnt move sorry. It sways to the front.

 

when you rev the engine? the car seems to rock to one side?

thats normal i think... its been a while since ive been behind the wheel of the lt1.. but i think thats normal
