Here is quick dyno pull to show how much power you can pull out of Matt's awesome Tyga header! I highly recommend these with the Akrapovic "open" system for even better gains. Using both together allows fitment on the 2017-2018 bikes!

After weeks of rain, and rain and more rain... we finally got some good weather and were able to complete our Brake Testing.
So prior to doing any brake upgrades, we went out and tested the STOCK brakes.
Tire pressures were all checked, brakes were seated w/ plenty of pad material...
the akro pipe has a db killer, but no hex on the nut to remove it. Anyone take it off? If so what were the results? Obviously more noise, but any power loss?
