Default F4i mods

hey i got a 2002 f4i and i wanna get the full micron exhaust system i was just wondering if anyone has it and how it sounds/performance? and if i get the exhaust i was wondering if its worth it to buy the power commander ive heard its worth it and some people say it doesnt make to much of a difference also i was wondering if anyone knows a compny that makes velocity stacks...or my buddy does formula racing for his college and had spare rr stacks will they fit/are they an upgrade?

thanks for the input...first time posting nice to be here

micron has good systems. you dont have to have a PC but it is good to have. With a full exhaust, you are going to want to have it dyno tuned as well. I have never seen stacks for the f4i but i think it would be a waste of money and will hinder the powerband.

id have to get it dyno tuned? isnt that what the power commander is for? and is their a better website besides kneedraggers to look for exhaust...i like the micron cuz the ylw/blk can matches my paint scheme but im not to interested in a high mount from the look of the pictures i wouldnt be able to pack anyone unless they want their leg skin graphed afterwards.....since u guys know more then me what would u say is the biggest bang for my buck performance wise (i have wheelie fever...first rocket but im a MX rider)

I would suggest a -1 +2 sprocket conversion then.
I just got a -1 Vortex front and a +2 supersprox rear with a EK x-ring chain for about 200$ and is the best mod I have done yet on my bike, i have much more torque now.

a dyno tune will be best for optimal performance with a full system. Wont need a dyno tune for just a slip on but a full system I would advise. The bike will run more lean with a full system rather than just a slip on. you dont HAVE to have a dyno tune with a full system but it would be a good idea IMHO.

best chain brands I would recommend are DID, EK, Regina
Sprocket brands, Vortex or AFAM.

You dont need any mods to satisfy your wheelie fever. You can easily ride for miles on the back wheel on a stock f4i.
