Then leave the stock midpipe alone, it flows very well. Major hp roadblock w/ our exhaust is the manifold. Only way to get decent hp increase out of the exhaust system is via long tubes w. or w/o high flow cats. (even shorties arent worth it). If your just considering midpipes, save your cash for another mod. Straight through axle backs are good for a couple of pony's but mostly just changed for sound....
