High Revs is making the rear end make thumping noises!!!
Heya,
I just got a used 2007 RX8 with 5k miles on it and when I rev the engine the rear end makes a few thumps which to me looks like it might be the exhuast. Anyone know what this is exactly or if i should get it checked out?

You mean it pops when you let off the gas?
I believe the heat from the exhaust is igniting the unburnt fuel.
If you have a catless midpipe you can shoot flames when it pops
