Another question from me...:-D
Have installed my arrow 4i1 full system on my R1, but it uses more space than the original exhaust. Am I doing something wrong? Should it use more space than the original? Any manual avaible on the internet? And so on. I'll might be able to upload a picture tomorrow

i also got arrow and it fits fine , i cant take pics right now , maybe in a few days

Oh that would really be nice. I am also very interested in how it is located under the right side of the front of the the engine and the middle exhaust mounting bracket.
Thx.!

i bought the bike with the system , so i'm not realy shure if its full system , i think the 4 pipes coming from the engine are oem and only the mid pipe is titanium (and the can ofcourse). i'll check that out later .

all 4-1 systems push down on the bottom. Best is to make a nice clean cut at the bottom before the plastic heats and bulges.

sorry for the long wait , u probably dont need the pics anymore, but if u do , here's my sutup:)
