ROCKET EXHAUST
Built using our black hard anodized octagonal aluminum muffler housing and carbon fiber end cap from our full-size exhaust systems. The Pit Bike”Chubby” is a short muffler design that features increased volume which adds power and makes an awesome sound. It’s our big bike muffler with all the features including carbon end cap, CNC hanger bracket and four bolt serviceability. Dynoed many different tube and core diameters and made best overall power. Sacrificed .5 hp on top to gain bottom and mid.
- Octagonal-shaped large volume muffler housing means more power and better sound
- Stepped head pipe diameter maximizes bottom, mid and top power over a single diameter design
- Carbon fiber end cap
- Rebuildable with simple hand tools, no grinding rivets.
- In the event of crash-damage, all exhaust system parts are available individually
- Optional “Backyard” quiet core available
