Bike was an 08 with pipe, fuelatv intake, motoworks fmu. Tuned the best of my ability. The rossier pipe was able to get a nice straight line on afr. The motoworks was pretty straight but I couldnt get the rich dip in the mig range to come out. Not to rich but part of the reason why the rossier beat it in the mid range. Then the motoworks took over. Both pipes had over 10 runs on each pipe and this is the best I could extract out of both. Thank you to Johnny motoworks for supplying the pipe to test and Crixal for letting me beat up on his pipe. LOL
For me the motoworks is a hands down winner. I think with a power commander the mid range gap could have been lessened and the top end on the motoworks is killer. Though the motoworks unit works just fine and was very easy to use. No computere needed to use it. This bike needs to be revved and thats been known since its debut. The bottom was about the same on both pipes. Not to mention the motoworks made this power with the sparky and is close to 10db quieter. Thats the deciding factor for me. It was way quieter.
Here is the graph. This was on pump gas. Not to shabby. Bike runs good with either pipe. Riding down the street you could feel the motoworks pull through the gears harder.
