Akrapovic Slip on - CBR250R

First mod - CF Akrapovic slip on

Fitment - very simple - two bolts. However taking the old graphite exhaust gasket off (at the slip on junction between the standard pipe and the aftermarket slip-on) can be tricky. If you can manage to fit the slip on over the stock exhaust gasket then do so - otherwise, hammer and flat head screw driver chiseling away will do the trick. New gasket is tight to go on and can be difficult to get it all the way in without damaging it so you're definitely better off leaving it alone if you can.
Exhaust db level will be above legal limit even with the silencer in place. The rasp is aggressive with moderate volume level. It does make drivers a lot more aware that you're next to them which is a huge plus - the standard exhaust makes the bike hardly audible. 
Fitment of the carbon Akra (among with most other slip on systems) will result in boycotting the oem catalytic converter as it is located in the oem slip on. As a result theres a bit more fuel smell on cold starts. If you wish to keep a cat in place you can purchase the stainless steel Akra which can be adapted with Akra's catalytic converter. 
There seems to be the tiniest improvement in pick up at high rpm - hardly noticeable. 
You will notice some plastic burning smell as the exhaust wears in - after about 200/300km's it was gone.
Last but not least - the weight saving is tremendous! The stock slip-on with heat shield weighs around 7kg. Akra's system weighs around 2kgs.
Happy riding!
