Torq Master Pipes specializes in building pipes specifically for the Honda
GoldWing line of motorcycles. Torq Master Pipes will make your GoldWing "sound like a motorcycle oughta".
But these pipes are not overly loud. All Torq Master Pipes are built using a DYNO JET 150 dynamometer to insure a Torque and Horsepower gain in addition to a little more sound
Torq Monster replaces the "Pre Muffler" on the GL1500 (it's not a catalytic converter), also separates the left exhaust from the right exhaust creating a true "Dual Exhaust". This allows the GL1500 to put out the Torque and HP Honda designed into it...you'll think twice about buying an 1800 after you put Torq Monster on your older 1500 WING. 95% of the time carb adjustments are NOT necessary for optimum performance.
