PS Flowmasters bite....
FlowMasters not only bite they suck ass too!!!
I can tell you flat out: No cats, resonator, and 2 small turbo mufflers will NOT cut it!!!
Rasp here, Rasp there, practically Rasp at idle...
I can't believe more people haven't complained about this before... It's like the muffler heatshields are loose and rattling constantly.

Except there are no heatshields...
I'm even contemplating putting a cat back on to help kill the rasp!!! (and bigger mufflers of course!)
