EYy guys. Ive narrowed my exhaust search down to the akrapovic. i have an 05 zx636 and think this exhaust looks the best on my bike. Just woundering if there is much of a sound difference between a slip on exhaust and a full exhaust. Not really after extra ponies just want the bike to sound alot better and alot louder. Is there much of a difference in sound between akra slip on and the full exhaust or is the main difference in the performance?
