Its got a 4-1 header, nothing great, actualy needs to be re-done better and a 52mm 304 stainless system (dairy grade) with a glass pack and a 300X200 straight threw center in side out silencer before the rear axel,, 52mm right to the back with a small 30degree turn down. On light throttle its actualy quiet but man it makes a big noise when im on the loud pedal, but its good like that, it lets people know they about to get passed ha ha

You can see the header pictures under my project build:
