The tapered head pipes and full merge collectors are engineered to provide maximum performance, significantly enhancing exhaust flow and power output.
A distinctive feature of this exhaust system is the “Competition Only” riveted Vance & Hines logo badge, a mark of quality and performance. The slip-fit collector joints ensure a perfect, secure fit, while the tuned length megaphone, which ranges from 1-1/2″ tapered to 1-3/4″, 4-into-2 collectors from 1-3/4″ to 2.00″, and a final 2-into-1 collector of 2-1/4″ to 3″, ending in a megaphone tapered from 2-1/4″ to a 3-1/2″ muffler can stepped to 3″, offers unparalleled exhaust efficiency. The system also includes an optional baffle for those who prefer to customize their sound profile.
Designed for precision monitoring, the exhaust features a single, 18mm oxygen sensor bung compatible with both stock O2 sensors and wideband air/fuel ratio systems. This allows for optimal tuning and performance adjustments.

This premium exhaust system comes complete with exhaust port flanges and a spring puller tool for installation. It is compatible with all GSX-R1000 models from 2017 to 2024, though installation requires a lower fairing modification for which guidance is provided.
