These are great points, and you know who has Sprint Filters always in stock ?The forward facing design removes a bend so it increases the flow slightly over the previous design as I have on my 899.
I would like to switch myself, however since Ducati moved to support Akrapovic, they now longer provide an upmap kit. I could keep my RACE map unlocked and just swap the exhaust, but if I sold my Termignoni to another 899 owner, I would feel obligated to provide the upmap as a kit unless they explicitly wanted to install the RapidBike or tune it.
Anyone on the fence on an upgraded exhaust will find this to be an excellent alternative to the Akrapovic.
You will need to make changes to the AFR to take advantage of the increased flow and consider a Sprint filter.
Ultimately, it will smooth out the midrange and remove some of the grumpy attitude...
i got my slips via eBay for 1700 usd - they do not include an upmap
most vendors include a sprint filter with sale which mine came with
going with rapid bike for my tuning .
