2:1 Boarzilla exhaust system is a stepped header system at the head is 1 5/8″ to 1 3/4″ to 1 7/8″ at collector and 2 1/2″ where the muffler goes to the header.
All Boarzilla full systems are equipped with heat shields, flanges and exhaust gaskets, bolt kit and baffles. This system has both 18mm and 12mm 02 ports so that it can be used with a Thundermax Auto Tune or a Dynojet Auto Tune if desired.
Every pipe is designed to increase low-end torque and horsepower. Performance increases are about 15 percent with the proper tune on the bike. Each exhaust system is designed and dyno tested at their facilities.
The Boarzilla 2:1 exhaust is for bikes that have 113″ to 131″ motors.
This is a great sounding exhaust system.
