    Thanks for the contact, I'll get prices.

    Mr Meat, so u think this thing is a Supercrapp, but with Euro tamper-proof device? Say yes, so I have a good argument for grinding it off.

    Chris, sorry but your Supercrapp hanging from the rafters must be a fake, because nothing is made in Dubai. We only do money-laundering, sell oil, etc.

    But I have proof. When I took my 'Crapp apart, it was stuffed full of UAE dirhams.... :rofl

    Yeah we stuff them full Dirhams and ship them to Afghanistan. Good business. Sometimes we even use banknotes as muffler packing on our bikes here.

    I drilled a hole in that mystery plate but the biggest bit i have is 12mm so I can't see much behind it. The plate is quite thick, maybe 2mm. I'll cut the whole thing off tomorrow, it's late here and the neighbours, etc etc

    There's a slight increase in volume, not much. It's still a very mushy sound, like "woosh woosh" as opposed to "doof doof", or something like that. More thumfer than thumper.
    And a bit of popping when I throttle off.

    Could be an air leak in the exhaust, but probably jetted a little lean. Most bikes are standard, to get through emmisions testing apparently.

    One about the same diameter as that dimple in the center of the baffle would be a good start. :wink:

    I tried to get a hole saw today but I could only get one for use on wood. This is Dubai, remember.
    When I get my next wooden muffler I know what to use.

    You got a Dremel? Perhaps that cutting bit might work in there to just cut the whole back plate out? :dunno

    Not a dremel, but I have some drill bits for grinding, they should be able to get through. Or else (worst case) I'll drill a series of holes at each weld and just break through with a cold chisel. That sounds heavy handed but nobody's ever gonna see the ragged edges.

    This sounds pathetic but there are very few proper hardware stores here and most are mostly garden furniture and building supplies. Some tools & supplies that you guys take for granted are hard to come by. Couple of weeks ago I was looking for engine enamel (that heat resistant spray paint) - not a chance. Torque wrench? Nope. And Krylon Fusion paint for plastic? In my dreams.

    eBay?

    The only problem is occasionally folks will balk at your location; maybe shipping costs would suck. But there is lots of stuff on there...

    I got my CDI torque wrenches off of eBay for a fraction of what they cost new - and they were :evil (the horde goes for Snap On because they are well know and pass up brands they don't)

    eBay - Location is a bit of an issue, about half (or more) suppliers aren't really interested in shipping outside the US.
    But the worst problem with eBay is the delay factor, when I want something I want it NOW. Waiting around for stuff to finish a job, freaks me out.

    I end up doing a patch-job with makeshift tools rather than wait a week or whatever for the whole bidding process, shipping etc.
    Impatience is the mother of invention.
