how much gain?
My mods are listed below. My catback is 2 and half inch dynomax with dual cats and only one intermediate pipe. I dyno'ed at 274 RWHP on a dynojet. Does anybody think going from dual stock cats to one 3" cat in and out with 3" cat back (most likely flowmaster) will gain me 20 more RWHP?
