^^That is a 5.0 pushrod motor, not a mod motor. If he would switch to a bullet style muffler, he would get more HP and TQ. The only HP he gained from that system was from the free flow tubing that came with it. The Flowmaster pretty much flows the same as the stock unit, if not less.
As you can tell...I think very highly of Slowmaster
They sound 'ok' but the numbers just suck.
