Martin. This looks great. Do you have any more pictures from different angles? Seriously considering changing my Carbon termi front exit cans for this full system by SPF.
Thanks for the pics Martin. Looks fab. How did you find the longer exhaust affected the bikes performance? What’s the throttle response like? What area of the Rev range benefitted the most? Many thanks
I only have the short cans, I’ve ask for the longer ones for track days I have 3 dyno runs, 1st as stock (171hp & 85ftlb at the wheel), 2nd as stock but remapped (183HP & 92ftlb), 3rd with SPF system & remap again (191hp & 103 ftlb) All at the wheel and on the same Dyno. depends on your riding, you'll know what the stock setup feels like. the stock remaped set-up was really tractable through the whole range, and was lovely. with the SPF system, its not lost any of its tractability, but due to the size and free flowing, it was tricky to map below 3K... but after that, chuff me its hauls.... pulling strong all the way though. as was shown on the graph. throttle response is epic, its a controllable missile . Phil has done the same tests with the system with the long cans, with no change in power delivery. so i cant wait to get my long cans to let me back on the track all the best Martin
Hey Martin When I mentioned the longer exhaust, I was referring the length from manifolds to cans. The stock setup is shorter ending under the bike. Your setup, utilised eventually by the wsb team, is overall longer. I was just trying to understand the development of this by the factory race team. ATB
AH i see what you mean, well all i can say is its way better!. as for the development, Phil will fill you in Martin
