hey guys im looking at the cermark alleycat and want to get a good idea of how fast this thing will go with a 91fx and tuned muffler would go? I currently have a gp shoestring with a 91fx and pitts muffler that has been clocked at 125mph. Its fast but not fast enough for me. What do you guys think the alley cat would do with 91fx or maybe a gms 120? I have read the posts that are on here and havent found any good numbers.

Thanks guys
