If you are chasing horsepower and torque numbers, the SuperTrapp 2:1 Fatshot Exhaust System is the exhaust system that you need to consider.
This exhaust has a tunable external disc-based muffler and heat shields that provide complete coverage. As always, this SuperTrapp exhaust is made of high quality steel to make it durable and tough enough for whatever type of punishment you can dish out.
The two 2:1, 1.75″ head pipes flow into a 2.50″ diameter collector before delivering into the tunable, 4″, external, disc-based muffler. At the end of the tuning discs, there is a solid end cap with a polished trim ring.
The importance of the stackable disc design is that it allows a rider to add or subtract discs to control and optimize the motorcycle’s powerband and sound. Changing the disk stack height can be accomplished in minutes and by using only basic hand tools.
Removing discs decreases the exhaust opening and increases back pressure. This decreases the powerband to create more low end torque. It also decreases exhaust tone and enriches fuel mixture.
Adding discs, on the other hand, increases the exhaust outlet and decreases back pressure. This widens the power band at top end. It also increases the exhaust tone and leans out the fuel mixture. Basically, what this all means is that you have the ability to easily tune your Harley Davidson to your specific riding style.
The exhaust has a deep, low tone that is also more radio friendly than most aftermarket exhaust systems.
SuperTrapp has long had a huge reputation in the racing. SuperTrapp’s proven performance on the track has made it a standard in the racing world for decades.
