Re: Puttin new Pipes on the truck... Should i have them Put an \"H\" pipe in ther
Quite a while ago I read an article in a magazine where they were testing different exhaust systems. All of the tests were done on a dyno using the same vehicle. They tested open headers, duals with an h-pipe, and duals without an h-pipe. The system that put out the most hp and torque was the full exhaust withOUT the h-pipe. I think that it depends a lot on the engine, pipe size, vehicle, etc...
