how many guys have re-packed their stock mufflers? i have packed mufflers before, but in the KXF one i was a little baffled (excuse the pun). standard run of the mill muffler is made up of the core, then packing, then the can. but inside the 06kxf muffler it has the core, THEN, a tightly woven mesh tube with fibreglass woven into it, then the packing, then the can. what is this mesh tube? mine was all oiled up so i did away with it and just put fresh packing in it. bike was instantly noticably different sound. and alot louder in the upper of the rev range. also noticed some better bottom end, i have some theries for the increase in torque. as the mesh is removed it has alowed expansion of the gas, reducing the velocity of the gas in the pipe, thus increasing the torque. i have also noticed it "trying" to pull in the upper rev range, a sacrifice in power. this would also back this up. which is not what i want. the bike also blew out a hell of alot of packing.
i include a schematic of the muffler, i have an arrow for where the mesh insert/tube is in the packing, i noticed that is part of the packing, not the core, and i drew a dotted like for where it travels through the packing. i will get pics of the insert asap.
you guys with after market mufflers wouldnt have this arangement.
anyone have any other insight to this?
perhaps anyone with a stock bike looking for more torque try this and see how you go. or anyone with a mod pipe wanting more power, slip in the mesh insert from a stock bike, see if that has an effect in the top end.
