Quiet light pipe

[JRE]

I am looking for an after market exhaust system for my DS 450 I am more concerned with lightness than power but it must be under 94db as that is the max allowed in Australia at the track. I love how quiet the bike is standard but the pipe is heavy does anyone know of such a pipe.

I just bought a FMF Q4 pipe from Leesons Motors, same place i bought my Motoworks pipe from. Should be a fairly quiet pipe. Will tell how it works when i get it. Takes a week or two to get to Europe.

Justin Reid, Justwin Racing, runs a LeoVince over here to pass sound regs. he swears blind by it.

For me it was a decision between LeoVince and FMF and ended up going with the FMF. The LeoVInce i was lookin foor was an enduro-type pipe with E-mark (In EU a road legal version) but it wouldn´t have been much of an improvement from the stock pipe. Hope I didn´t make a bad choice.

I'm in the UK fella, Justin is based in Ireland, there was an article in Quad mag on his DS last month, he is running a full pipe with CT engine mods, he swears by it for letting it breath and the all important 94Db sound check

Q4 is supposed so have the max of 96db, but with mosts of the quads below 93db. Well see how it is with the DS.

Got the Q4 today. Can´t really tell how it works yet since my test drive was interfered by the police. After 200 meter driving I saw a police car parked by the road so I turned around and headed back to garage. Quite sure they didn´t see/hear me and didn´t wait to ask...

Anyway, the Q4 sounds awesome. Not much different from the stock pipe which has no spark arrestor. A bit louder when pressing the throttle, but nothing compared to Motoworks... I´ll post a vid later. Forgot to take a "before-vid".
