Stay Pinned Stunt Pipe

STAY PINNED STUNT PIPE

High-and-tight 2-1 forward exhaust developed for Harley-Davidson Dyna stunt bikes

The Stay Pinned Stunt Pipe was developed with local stunt riders to create the clearance and layout they wanted. Its high forward collector and single rear outlet keep the system tucked close to the motorcycle, helping provide additional clearance for drifting. 

Stepped headers, the SQ1 collector, and a Neighborhater-style baffle deliver the performance and hard-hitting sound expected from an SQ1 pipe. Built to stay high, tight, and pinned.

IMPORTANT RIDING NOTE

This system is designed to improve exhaust clearance, but no exhaust can guarantee contact-free operation in every riding situation. Verify clearance throughout suspension travel and at your intended lean angles before aggressive use.

TUNING

A proper EFI calibration is recommended after installation. Carbureted applications may require jetting or fuel-system adjustments
