| Re: B&B x-pipe vs. resonator
I have B&B, and have had all the setups with/without headers. (my headers have hi flow cats integrated, but made the biggest increase in noise - good noise)
Resonator/manifolds: Subdued and good throaty quieter sound
Xpipe/manifolds: Throatier sound not too loud, great a WOT
Resonator/Headers: Deep throaty sound, rumbles a little at idle (but not too much) people pay little attn at idle unless you rev it up, loud at WOT
Xpipe/Headers: Deep Rumble Throaty, rumbles at idle, people know something is done to your car, sets off car alarms, sounds like heaven at WOT  :  : 
Can't go wrong with any of the setups really.....the sound can't be beat!
