Fabrication of several different exhaust systems to reduce restriction and improve tone. Upgrades to the exhaust system. Stock was 2.25” diameter with a very inexpensive muffler and was quite restrictive. It became particularly loud and raspy over time. New systems are 3” and fabbed to allow quick swapping between several different mufflers depending on the event/activity. Fabrication was handled by Furo Racecraft in central WI.
