I'm running a single 3" exhaust with a 40 series Flow, 3"inlet and dual 2.5 outlets dumped in front of the axle on my 83 Silverado with a 4/5 drop and I love the deep rumble
have recieved some compliments on the sound and set off a few alarms but hey when your 51 and having a mid life crisis
the louder the better
