Hey guys great forum been checking it out for since i got my f4i. What im looking to do is put a RR system on a F4i. I got the entire setup for 100$ so i guess ill give it a go. My question is does anyone know if the Headers will bolt up to my engine. Thanks!

 

This requires extensive modifications to the bike. You need to change the rear subframe and plastics, seat, the swingarm, possibly modify your fairings, rear brake, etc. Then paint it all to match.

 

I dont think RR headers will fit a F4/i engine for starters. Not to mention all the modifying of the aft section that will need to be done to ensure you dont set your **** on fire n more importantly melt you whole tail section.
