I can't decide on the fmf power core 4 slip on, or the big gun complete system. I can get a new fmf for $150 w/o any jetting, or a new big gun with the jetting installed for $450. I don't plan on doing any internal mods, just better air cleaner, maybe cdi/revbox. any help would be appreciated.

 

My opinion Big Gun SUX. Have you priced an Alba full exhaust? Ive heard they are very affordable and you get ceramic coated head pipes. Ive got a Ron Woods racing full exhaust but I had a Yoshi slip on first and was very happy with it. My bud has a Pro Circuit and its also nice. The White Bros R-series is not one of my favorites. Its sooooooooo loud. Just thought Id tell my experiences. Hope it helps.
