Default Full Race Exhaust Question for F4i

Hi all. Appreciate the earlier responses on the revalve/respring front end. Bike headed to the shop in a few weeks for the work...decided not to swap the front end for a 929/954. Have a new question for which I would appreciate opinions. As I convert the F4i to a track bike, I want to move to a full race exhaust from the Jardine can I have now. Does anyone have experience/opinions/views about the best systems or what has worked best for them? Thanks

get some used from ebay any known name and spend left money in better way. for example buy radial front brake master cylinder (F4i have small and old style), SS front brake line, as it is not new bike rear shock needs oil (good oil) change, race clip-ons, race rear sets. last two is necessary for right position on bike. actually this all you have to bay before race pipe

I bought a full M4 system..I also have a Jardine, Hindle slip on that both bolt directly to the M4 headers....They were very nicely made with excellent build quality..I would also suggest looking at the Hindle header as well..Akrapovic is way too expensive and I also heard that the micron ultra lite works as well however some have had fitment issues when hooking up to another brand slip on...If you have any other questions let me know...this is what the M4 looked like...Cheers...

cheapest way is to get a set of micron zeta race headers then get a custom exhaust midpipe and any kind of muffler u want, that is a custom race exhaust, make sure you look at the inner diameters of everything closely and double check too! you want good all around power so you have to have small pipes at the headers and large collectors, the race headers have 60 mm inner diameter collector inlet!

anyways the way i told you require more of a patience and lots of calculating too...but it is going to be truely unique and worth every penny!

thats my advice
