yea its a standard ct9, was quite suprised by the result to be honest, only got a mani, down pipe, air filter, blitz bov and front mount on and at the time it was done it didnt even have a full exhaust system on it! it did start geting worse gradualy, been off the road for over a year so dont know how bad it is now, should be back on the road soon though and see what its doing. but you guys reckon actuator then yea?
