This episode of Engine Masters presented by AMSOIL delivers the goods many viewers have asked for as we test the power of straight dual exhaust with no crossover pipe versus using an H-pipe versus an X-pipe. Will the old bench-racing stories come true, or is it all hocus-pocus? We find out using a basic 5.3L GM LS3 engine then precisely spell out the effect these exhaust-system modifications have on horsepower and torque. Engine Masters is supported by Auto Meter, Mr. Gasket, Earl’s Vapor Guard hose, and now Permatex!
