Hello everyone, I'm selling the Toce full system that I had on my B-king since it's getting a turbo. It should fit all years Busa and B-king, but was marketed as a Gen2 Hayabusa system. It has a bung welded in for a wideband O2 sensor that I will also include a plug for. One header has a small dent on the bottom from loading it into a trailer. Sounds almost identical to my buddies Busa with a Brocks alienhead system. Asking just $500 shipped in the US for it. Link is here: Razor Tip Full Exhaust - Suzuki Hayabusa GSX-R1300R (08-20)
