Bought, and installed an older stock KLX head pipe and muffler, along with airbox mod, and rejet. Bike runs tons better now, but is a little louder than I want. I bought some re-packing material to see if it helps.
I took the 2 bolts out of the end cap, and 1 bolt out of the bottom of the muffler near the end. I can not get it apart. Should it come apart?
Figured I would ask before going the BFH method!
Thanks!

 

No, it does not come apart. That end cap should extend down into the pipe unless someone modified it. My brother put a little turn down tip on his. Probably helps a bit, aiming sound waves down.

 

The stock muffler uses metal baffles like in a stock car muffler..............no packing material.

Ride on

Lol! Glad I asked before getting too heavy handed with it!
Thanks guys!
