    Leo Vince baffles

    Hello Everyone,

    I recently bought a 2007 Tuono Factory with the standard exhausts and found and bought a pair of Leo Vince titanium exhaust on ebay. They came with a set of baffles

    I noticed that one of the baffles didn't have a cone welded to the end where as the other one did the.

    The one with the missing cone didn't have any signs of a weld that had broked so I can only assume that that they came this way from the factory.

    If that's the case is there a particular exhaust (i.e left or right) that the coned baffle fits into?

    Weird. My Leo's had DB killers that were similar to yours (quite a bit shorter however) and each one was identical. Can't see why they would be different by design...

    I've had a couple of sets of LV's. Those don't look familiar at all.

    I have the left one in my 2003 Mille R's Leo. Bought it after the exhaust directly from LeoVince, so I can vouch for at least the left one being a genuine LV part. The right one looks like the open flow design version of the left one. Also available from LV. Was looking into that but it wasn't legal for said can in germany. Plus, the left one hardly takes any sound, too. Gonna have to repack at some point..

    Plus, if I had to choose, I would put the right one in the can for the front cylinder and the left one in the can for the rear cylinder. The reason, which does not make too much sense of course since the exhaust lines have an intersection anyways, is that when opening up the exhaust system (better flowing cans), fuel mixture in the cylinders tends to get a little leaner and since the rear cylinder likes being run a bit richer than the front (rear tends to get hotter because of it's position, though needs a bit more cooling which is achieved by a slightly richer mixture), I'd put the more "closed" baffle there, so that the rear cylinder gets less flow and runs richer. As said, doesn't make too much sense because of the intersection and I bet it doesn't make any significant difference at all - but why not do it, when you have to choose anyways. Cheers.

    The difference is interesting- I recall that mine do not have a conical end - previous owner must've replaced one at some point

    It is known that the left pipe flows a bit less as noted in post 4 above; less sound. For that reason I would put the pipe with the cone on the right side.

    Yeah, air cooled twins like the Harley or similar layout old Indian or British twins, the rear gets less cooling so runs hotter. Not an issue with water cooling. No need to be insulting about it though.

    My guess would be they are a mismatched pair for what ever reason. (One bought later replacing a misplaced part etc)
    It's obvious that the open one will flow more and be louder. You might try researching to find out if they made more than one type for different noise levels and flow rates etc.
    Incidentally, the closed one looks identical to the ones made by Delkevic.
