looking at buying a Leo Vince SBK Oval EVO-II Racing Slip-On Exhaust w/ Conical End Cap,
the discription says "factory slip-on", does this mean that when i install a power commander, and air filter, the slip-on will do just as much (horsepower-wise) as my factory exhaust, just sound better? or will i get a good power gain?
thanks..

this subject is been cover many times, theres also dyno results to compare with slip ons and full exhaust for a better answer you should try 600rr.net

but from what i read leovince and Akrapovic is the favorite hope this helps.......

your going to get a little better air flow with the filter and slip-on but it wont be much of a gain unless you get a full exhaust.

 

slip on airfilter and a power comander your lookin at like a 6 hp gain if you just download a map....if you actually have it tuned and have the powerband changed the bike will feel alot better and u might end up with another hp or 2...power comanders dont add hp the just change the maps around for a more usefull powerband....but deff check out 600rr.net very good info on that site
