    OK this is going to be more than likely repeat question, What damage can come about from fitting after marking slip ons that allow a heap of free flow of exhaust out , with out changing the air cleaner or remapping the ECU, I dont have any details of the make of slip on, i purchased the from ebay about 3 years ago to do up an old bike i had back then and have since forgotten the detail of the ?? any help would but appreciated.

    P.S I haven't changed anything else.

    cheers

    These pipes do have baffles of some form in them, but i will keep looking any markings on them,

    Thanks guys for the heads up, plugs look fine but i will monitor everything

    Cheers

    I scanned the slip ons today while i gave them a polish and there isn't a number or letter combo of any kind on there.. will have a look on ebay history and see what i can come up with.

    Cheers

    That lean condition will raise the cylinder head temperature which could burn an exhaust valve. flhrrider
