Exhaust

Upgrades to the exhaust system. Stock is 2.25" diameter with a very inexpensive muffler and is quite restrictive. It became particularly loud and raspy over time. New system is 3" and fabbed to allow quick swapping between a Borla Sportsman and Cherry Bomb Vortex muffler. It flows much more freely and improved the sound considerably.

I decided to try a second muffler (this one with baffles) to see if it is a quieter option.
