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!

Custom Machine & Tool Co., Inc. is a US manufacturer of timing pulleys, drive systems and components for the motion control and power transmission markets in operation since 1964.
CMT has developed and patented (US patent #6,568,063) a new and revolutionary hub to shaft
connection device, which allows for precise component positioning and tight runout control on demanding applications. At the same time it is easy to install and remove, and is economical to manufacture. Our keyless hub to shaft connection device has superior features and benefits compared to other connection systems such as keyways, pins, set screws, clamp collars, and other tapered shaft locking devices.
The new system, called Concentric Maxi Torque, is available for immediate inclusion in our full offering of timing belt pulleys and can be designed into any custom application. We are confident that you will
not find another hub to shaft locking connection system device or system that provides a better solution to your motion control and power transmission shaft attachment requirements.
