if i just get slip on for my 01 f4i do i need to get it remapped?

 

It would run better with one,but not necesary.

 

I run a slip on without a pc3. no remapping

 

simple answer is no. even more simple is you dont need a pc in order to have an exhaust.

 

but the pc3 does give it that full potential. but def you dont need it unless you have the extra money. so buy your exhaust and post some pics of it when you get it

 

yeah i run a slip on without a pc3. but coming from using 2 kinds of pipes, it just depends on how they perform on your bike. some you can find flat spots on certain rpms where it doesnt pull hard as it should. that's when u can tell that you need a pc3

 

+1 on everything said above....really..some pipes might make use of a PC...but likely, any increase you get using a PC is going to come from the better throttle response and the improved injection, not because of the exhaust...exhausts don't typically add that much to the bike...they are more sound....now a full-exhaust and you are talking something different, but with slips...nothing really...

you shold get a PC to smooth out the throttle and just overall improved the bike performance, but it won't be due to the tandem of PC and exhaust, you're just optimizing the bike...plus, to even get anything from a slip or full exhaust, you'd likely want a custom map, not a d/l'd map.....

 

yea i dont have a pcIII either and mine runs great (knock on wood)

 

also... if it's throttle response you're looking for, try adjusting your freeplay less on your throttle to make it a bit more punchy. if it's still not what you're looking for, pc3 might be what you want in terms of throttle response

 

Not necessary but worth it IMO.

I just went from bone stock to Yosh RS3 slip on and K&N air filter, didn't notice much difference in performance except it might not have revved as quick as before. A couple weeks and a few rides later installed a PCIIIwith the PC map for my setup and noticed some improvement in throttle response and not as abrupt on/off transition. I might spring for a custom map some day but I'm pretty happy with it now.
