Does anyone have a guess what adding an H-pipe to the exhaust does to the sound of the exhaust? The engine in question is a 292 that's stock except for .080 overbore,59 distributor with Pertronix and 57 4 barrel intake and 4100 Ford carb.Exhaust manifolds are 56.The exhaust is 2 inch all the way with Thrush mufflers.Will an H-pipe make it louder,quieter,sharper,more mellow or what?Right now it is very loud and has a sharp tone,not the mellow sound a stock Y-block has.
