i have just fitted a sportex exhaust backbox and im not too impressed with the sound, you can only really hear it at over 2000 revs, is there anything i can do to make it deeper and constant, also making a sporty noise when just ticking over? at the moment it just sounds like there is alot of air from the engine and exhaust, would an exhaust system do the trick???
