2021 Suzuki GSX-R750 Pearl Brilliant White

ENGINE DESIGN

The four-into-one stainless-steel exhaust system features four individual head pipes and a single collector.  The mid-pipe located between the collector and the under-engine exhaust chamber carries a Suzuki Exhaust Tuning (SET) servo-controlled butterfly valve to match exhaust system back-pressure to engine rpm, throttle position and gear position, maximizing torque and improving throttle response, especially in the low-to-mid rpm range.  The exhaust chamber leads to stainless-steel S-bend pipe and a titanium muffler shaped and positioned to enhance cornering clearance and improve aerodynamics.  A reduction in pipe wall thickness and a smaller, more efficient exhaust chamber and muffler combine to make the GSX-R750 system 1,100 grams lighter.
