    Seems a bloody good concept, so I'll look forward to seeing (& hearing) it on a rideout. The slash-cut is a nice idea, but due to personal taste (only), I'd prefer if it was rotated by 90 degrees so that the slash faced downward.

    I'm still tempted to know if the same principle could be applied to a shorty exhaust as I mentioned yesterday. In theory, if the 'silencer' part (ie the bit containing the baffle) started underneath the bike where the link pipe normally connects and continued for maybe 550mm or so, this shouldn't affect BHP too much... or am I getting this wrong?

    Whaddya reckon?

    A whole can of worms to tune exhaust to engine to power chacteristics to noise

    Yes GuzziRob - it does all seem to be a bit of a hassle. I certainly wouldn't want to compromise on power and need to keep hoise levels reasonable for track days.

    I was previously thinking of an underseat exhaust, but that would mean cutting a mounting lug off my frame and moving the battery etc... and I can't be arsed with that. I'll leave the bike as it is, especially since (apart from the tank) it's now all back together and looking pretty good, even if I do say so myself :).

    Well I was sent some proper silencing material by a very kind gentleman on another forum. So I packed the 250mm long by 35mm bore baffle , polished up the "silencer" and refitted it today. Whadya reckon;

    Double click on the piccy to listen to video.

    It ain't gonna get any quieter than this unless I fit a pre silencer under the engine. The standard exhaust system has a four into two into one which is about 48mm diameter welded to the linkpipe which is 61mm diameter. Not sure what goes on inside the link pipe, but there aint much silencing! Here's a coupla pix of the collector and link pipe;

    So I will either redesign the link pipe with a silencer in it or fit a 4" diameter pre silencer and a serpentine link pipe, as fitted to late model Blades with aftermarket Yoshimura or Akrapovic silencers.

    Looks very pretty! Have you taken it out for a spin? If so, how's the power / noise?
