have a spi ceramic coated single pipe here for 03 to 07 rev 800. they claim 8-9 peak hp on the 03 and 04s, and 10-11 on the p tecs. worked good. no longer need pipe. its pretty good shape. some wear on the coating, and under neath there is some wear marks from rubbing the frame cause this pipe is bigger than the stock one. not really a big deal. not through the metal, and its not seen. asking 200. pm me if your interested.
