850 REV G4

We have a single pipe and Y pipe for the 850. The pipe produces 5hp gain and runs at 8000 rpms. The single pipe is available in a low altitude version and a high altitude version. The single pipe works fine with your stock can. You can add a Y pipe and gain an additional 3hp. You will need to get a new exhaust donut to go with the Y pipe. The Y pipe will NOT work with the stock single pipe.
