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.
Addition of a Cherry Bomb Vortex muffler. Had to do it twice, actually, since the first Vortex muffler went bad and began blowing out its packing material.
Installation of a Magnaflow muffler.Magnaflow is a sponsor of the Hot Rod Power Tour event, so I decided to give one of their mufflers a try on the Atom. They're polished stainless and look great - too bad they're usually not visible after they're installed.
