Header Mod-Lite GSXR 1-1/2in x 1-5/8in

The SCHOENFELD Header Mod-Lite GSXR 1-1/2in x 1-5/8in (ML11703RVY) is a performance exhaust header system engineered specifically for the Suzuki GSXR 1000. This tri-Y configuration features 1.5 to 1.625-inch primary tubes that flow into a 2-inch collector, delivering optimized scavenging and improved top-end horsepower for sport bike applications.

Constructed from mandrel-bent steel and finished in durable black paint, the Mod-Lite design balances weight savings with structural integrity—a proven choice for riders seeking measurable performance gains without excessive system complexity. The tri-Y merge design is critical to GSXR 1000 tuning: by controlling exhaust pulse timing and combining primary tubes at the correct length and angle, this header maximizes the ram effect and minimizes backpressure across the RPM range.

This header is engineered for owners modifying their GSXR 1000 for increased displacement, higher compression, or aggressive cam timing, where stock exhaust manifolds become a restriction. The Mod-Lite construction achieves meaningful unsprung weight reduction compared to heavier cast or thick-wall alternatives, positively impacting throttle response and chassis balance on both track and street-focused GSXR models.
