LSA or Duration to fine tune glasspacks??

Gotta agree with AJ on the turn downs and if you live in the city theres no feeling in the world that compares to driving down an unlit street with the lights and horns of the car alarms from the parked cars going off as you rumble past . Damn I miss that I'm going to have to put mine back on for a couple of nights.I'll say hi to the neighbours for y'all AJ .
