Going to go ahead and put an h-pipe on my Fury. It's an LA 360, Magnum heads and 1.6 rockers, XE256 cam, dual plane M1, Hooker comp headers, 2.5" duals out to the bumper with stock style turndowns, and 2 chamber 40 series Flowmasters. My problem is how loud and poppy the exhaust is under part throttle and wide open acceleration since I did the head swap. I need to know what size h-pipe to put in. I always thought the crossover pipe should be a little smaller than the exhaust system. If that's the case, would 2.25" be ok? I'm just trying to quiet it down and clean it up a little bit. I hope the 2.5" exhaust isn't too big for this setup. Any opinions?
