| | Do I have enough exhaust?
My new head and cam combination is G5X() cam, and AS stage 2.5 (large valve stg 2s) 5.3l heads, milled to ~11.5 to 1 compression. My exhaust currently consists of Hooker LTs, Hooker ORP, and Hooker catback. I will be installing a 3" cutout in the intermediate pipe. My question is this, do I have enough exhaust, or would I greatly benefit with true duals? I have the BMR Extreme torque arm (with the crossmember that makes true duals almost impossible), and true duals would be a major hassle at this point, not worth a 3-5hp gain, IMO. Or would I gain signifigantly in going to a 3" x-pipe dual setup? TIA, Shawn
