Exhaust for 2001 LC4

Recommended Posts

Hey everyone,

 

Just bought a 2001 ktm lc4.  It has the stock Supertrapp exhaust.  The muffler rattles as if one of the discs is loose or broken.  I took the end piece off of the muffler, I believe it's called the baffle, and all I can see is a welded piece of metal blocking access to the rest of the muffler.  I do not know if this is how the pipe is supposed to be but I do not see any disc and I can not access the part of the pipe that is rattling.  I would like to replace this muffler as I think it is hindering the flow of exhaust. 

 

The problem is I am have trouble finding a pipe that will fit.  The pre-silencer makes fitting on another pipe hard.  It seems that I need to get a pipe very specific for this bike.  I have heard that Biggun makes it for this bike but I have not found one yet. Does anybody know where I can get a pipe that can replace the pre-silencer as well as the main muffler?  I am even open to replacing this exhaust with another stock Supertrapp however I would prefer to upgrade. 

 

I have attached some pics for reference.

 

Thanks

 

 

Also, first post!

I'm having the same problem with my 2000 640, just opened it up to check the baffles and ended up snapping 4 bolts and broke one of the welded nuts off the end cap... Got it back together but sure would like an aftermarket kit without dropping $1500 for an akra system
