Stuck with 2.5" on the LS6. Magnaflow exhaust. I like the attenuated rumble.. even better are the cutouts.. which I can open a little,... or a lot and really hear the rumble. Don't get me wrong tho.. the magnaflows definitely wake up when you get the rpm's revvn'.
Exhaust Cut Outs make it nice to have that option of scaring your neighbor and unleash the beast within', then quietly cruise on and enjoy hands free unit to take a phone call.
