Someone said it was normal in SRT-6s...I don't think I ever heard it before but also never stood near the back when someone gave it a burst in idle.
Thing with the spark plugs is that I would imagine it does it all the time, for example when coming to a Still-Stand at a red light but it doesn't seem to do it under load.

Probably doesn't hurt to replace spark plugs and coil packs anyways.

Is there a good way to test for exhaust leaks? And is there any patches for it or does it need to be professionally welded?

Thanks for all the info
