    Not complete yet but here's what I got so far..

    Removed left side exhaust.. Started drilling out rivets on both sides.. only the left side needs to be drilled out.. (I did both)

    Once rivets are drilled out on (I guess you would call it the engine side) take a screwdriver or ratchet end and tap out the core from the exit side.

    Cut the welds.. I used a dremel and a bunch of bits..

    Remove core (should slide right off once welds are cut

    I placed the mid-pipe back into the housing but will need to remove and place a hollow pipe inside along with exhaust packing as the exhaust will get HOT..

    Will post more pics as I fix the left side and gut the right..

    Awesome post! This info is especially helpful due to lack of after-market exhausts available for the 09 SMRs. Thanks motoxer311!

    Are you finished with both? I made it for a friend on a SM510 2009 too. Never again. To much work for nothing!

    So i just finished with the other pipe. If anybody is thinking about making the same, let it be!

    louder but not stronger.

    the bike from WMRRA063 we modifyed too. He has now one exhaust from a TE510 with power up kit from 2008. the best way. more agressive and lighter.

    sorry motoexer311 for using your pics, my cam was not charged.

    <------- Lazy...

    Still has 1 hollow exhaust and I need to re-rivet the left side.. Bike runs good and sounds good for being semi-stock..

    I am actually looking to go aftermarket on my exhaust now, any ideas on who makes good pipes?
