    Best Exhaust is Stock Exhaust?

    Ive been nosing around here for a while and see that some are saying if you put an after market exhaust on you lose power? any truth to this? I was wanting to do something to get a tad louder exhaust note while gaining in performance?

    The stock exhaust is 2" from the exhaust manifolds to the inlet of the mufflers then 2-1/2" from the outlet of the mufflers to the resonator tips. There are also two catalytic converters on each side. I don't see how putting on a larger after market exhaust could hurt performance. However, most engines are designed to have some back pressure, so going to open headers would probably hurt performance on a stock Marauder engine.

    Headers , or a Stainless works full exhaust will help performance greatly , if headers are done a tune is needed.

    On a N/A Marauder the stock system flows pretty well. The choke point is the mid-pipe. If you just want loud try removing the 2nd set of cats, delete the resonator tips or try a muffler swap.

    Come to Carlisle in June and you can listen to other members rides and see if any of them suit your fancy.
