So you used the Arrow GP that was made for the 600RR or 1000RR? ANy fitment issues? Have you had it dyno'd to see how lean you're running? Any problems at idle, low end, mid range?

I'm really curious about this. If the Arrow 600rr or 1000rr exhaust is interchangeable with the F4i this could be quite a nice little setup.

Forgive me for not being very mechanically inclined here, but it would seem to me there might be some problems of some sort using an exhaust here designed for a completely different motor. Am I wrong????

 

Hi Moto. Yep its the 600RR MotoGP exhaust. No fitting issues other than having to bend the mounting bracket slightly to fit (otherwise sticks out too much) and fits onto existing link pipe. No PCM fitted as I have not heard of anywhere yet in HK which has a dyno to set it up.
No problems with low/mid/top power, although up to 4500rpm the pipe sounds a bit muted. Not sure if the bike is running lean at the bottom as I always change my sprockets for better acceleration and havent done this yet with the F4i. Seems to accelerate ok so I think its me rather than the bike. After 4500rpm the rasp starts and it sounds like your shifting. Definite improvement in mid/top end as there used to be a dip around 5000rpm which isnt there now. I haverun the pipe with the baffle (removable) in for the last week and it shoulds lovely. I have had the baffle out and sounds awesome -superb copy ofMotoGp sound!! I will run itwithout the bafflesoon as I have been assured it willgive more power (as well as the sound)
Im notthat mechanically able but no issues with runningthe pipe with theF4i rather than600RR.
Personally it looks and sounds better than any other exhaustI have seen on theF4i - so it gets a massive thumbs up - do it- itscertainly a new look which will not be copied by many for a while (until they read the thread of course ..lol)
Now I just need to tidy the tail and it will look sweet.....

seeing how mine compares. polished frome and swing arm, upgraded mirrors, turn signals, grips, undertail, chain guard/tag relocator. And shorty CF bootleg exhaust.
