It works great on standard 50cc kits and sport 70cc kits. It starts to run out of steam on anything more revvy however. It's good value for money too. Well built and chrome for £102!
would it be a good pipe for the stage 6 sports pro cylinder or would i be better having the s6 pro pipe?
so your saying it would be more revvy and less reliable with a stage 6 pro exhaust than a pro replica??
