Has anyone put the dual outlet muffler off the 850 on the 550???I was checking this out over the weekend and seems everything but the dual outlets are the same.

 

bump

 

Have one on my 550 XP..everything is the same except the dual outlets..Have 3600 miles on it now..Only problem is everyone one thinks it is a 850..Also all my decals are removed..It sounds a little different the our other 550's..

 

I wounder if the back pressure would be correct for a 550 single vs a 850 twin. If if was a carbed motor you would have to re jet it for a change like that as with aftermarket pipes. Not sure about EFI piping changes if its just ,bolt and go ,or remapping is involved.
