Gas gassin, I couldn't really say for sure as I only rode my bike a few times with the original pipe and the carb settings were all over the place,I fitted my fresco when I did the top end rebuild, with different jets and needles and all that, but I have nothing but good things to say about the fresco it looks amazing sounds good, had not probs fitting it everything lines up perfect, I still have the fmf pipe but will be using a pro circuit soon, I'm sure if you have the full system you will be pleased.i love my gasser now it absolutely hauls ass
Oh yeah I did find another place the sells these in Canada May have been a bit easier for you
Blair, I found the guy pretty decent, I actually sent him too much money by paypal and he emailed me to tell me
