hasselferrit87 Posted August 7, 2013 Share Posted August 7, 2013 Hey guys sorry if this has already been covered but does the bosi system fit the 2013 evo? Will it just need a dent on back of front pipe to suit frame? Any help will be great Thanks lee Quote Link to comment Share on other sites More sharing options...

coriolis Posted August 7, 2013 Share Posted August 7, 2013 Fits straight on. Why on earth would you dent the front pipe?! Quote Link to comment Share on other sites More sharing options...
hasselferrit87 Posted August 7, 2013 Author Share Posted August 7, 2013 Because the 2013 hydro frame is different! So wasnt sure wether ut came out further hence denting the front pipe closest to frame! The ? Symbol clearly shows that its a question because i wasnt sure, i wasnt stating myself wether this has to be done! Quote Link to comment Share on other sites More sharing options...
benbeta23 Posted August 7, 2013 Share Posted August 7, 2013 I had the same problem with my front pipe, It fit the 2010 bike fine, But the 2011 bike, The motor was mounted further foward, So I had to dent the back of the pipe slightly and swap the bolt to a countersunk one, Bosi eventually brought out a new one to fit, Which I have just swapped mine to recently, Didn't know the new one wouldn't fit the 2013 bike.

benbeta23 Posted August 7, 2013 Share Posted August 7, 2013 (edited) Hi, First pic is the old shape pipe, If you look at the top bend you can see it is different to the new one, This is so it clears the engine mounting, Although it is very close to the small screw that holds the tank panel on my bike, Not sure what it's like on the 2013 bike. When I swapped mine to the newer bend I did find that it increased performance slightly on the bottom end.

hasselferrit87 Posted August 7, 2013 Author Share Posted August 7, 2013 Ahhh i understand! Does the first pipe fit as thats the pipe ive been offered! Quote Link to comment Share on other sites More sharing options...
benbeta23 Posted August 7, 2013 Share Posted August 7, 2013 You can make it fit by putting a dent in the back and use a countersunk bolt instead, It may fit the 2013 differently, I'm not sure, But you are probably best comparing it up to the bike when you get it to see what you need to modify.
