    I bought my Slim a few months back and earlier tonight completely removed the mufflers from the end of the factory header pipes. I know I cant run the bike like this so im looking for options without having to buy a complete exhaust system. Can I not buy baffles for the stock header pipes? A tech on J and P cycles told me the bike will run to lean and ill put holes I the pistons. Anybody have any answers?

    Welcome to the forum
    There are many options for the exhaust system and most will be less restrictive in air flow this will cause the mixture to get leaner
    However ecu should add a wee bit more fuel as it senses the increase in flow
    However factory systems are tuned to be lean to pass epa restrictions
    Adding a fuel tuner you can adjust the fuel flow to fully match the air flow

    Welcome to the forum.
    You could buy some slip on exhausts from any manufacturer Rush,Vance and Hines,etc.Your ecm will adjust for adding slip ons.You must get a fueler or ecm download if You get a free flow air cleaner.

    A set of Cycle Shack slipons might also be an option; similar in cost.
