Thanks for the replies. I want to put a system on the bike that improves the preformance but stays at or below 94 db. Doma do a silencer that they say is 96db but to get below 94db you have to fit a baffle so will be no better than standard.
Is the KTM Akaprovik system worth the money and is this within 94db or does it come with a baffle to pass the noise test?. also what is the JD jet kit and how does it improve the stock power.
I run a 40 pilot and standard jetting otherwise I find the bike is not as clean off the bottom as I would like, stutters from closed throttle,when you want to get on the gas out of a corneryou know when you crack the thing open.
I think the way the standard silencer is made does not let the thing breath. I realise this is to keep the thing quiet but is there anything out there that will give me what I want before I go and buy something that just gets me thrown off practice tracks and out of events, noise is a big issue over here in the Uk especially noisy 4 strokes.
Thanks for the advice.
