Built using our black hard anodized octagonal aluminum muffler housing and carbon fiber end cap from our full size exhaust systems. The “Chubby” is a short muffler design that creates big bike sound and increases power!

• 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
• Features including carbon end cap and four bolt serviceability
• ECU map available through CJR Performance to increase power if you open up the air box
• Re-buildable with simple hand tools, no grinding rivets
• Optional “Backyard” quiet core insert available
