Performance gain with K&N Airfilter and Akrapovic Slip-on Exhaust
Hi Guys...have any of you installed a K&N Airfilter and a Freer flowing exhaust on your 390?
Any noticeable performance gain from both mods?
I have ordered the K&N Airfilter for two reasons: It's washable and makes the engine breathe better...
I'm also waiting for the dealer to bring the Akrapovic slip-ons or distributors of Arrows and Scorpion to bring in their exhausts for the 390's being sold here. They say by December 2013 or Jan, 2014 they may have exhaust specifically made for the 390's as they already have the exhaust system for the 125,200's that are basically the same. Just that the 390's have a slightly bigger diameter exhaust tubing.
So if anyone has made these two mods...please let us know what performance gains have you achieved?
