what fits? Tried about 3 dealers, FMF customer service and no luck.

 

muzzy,2brothers,FMF,hmf,staintune. there's probably more but these are the one that we all use. go to the fmf website and you'll find a couple that fit. don't get too caught up with the year though. 06 and 07 are the same bike.

 

Parts unlimited has the part #s for the complete FMF in the Offroad catalog now,I have it on my bike and looks and sounds great. My q4 was $349. and the header was $199. it's pricey but makes the bike sound like a bike now

 

I have a header and slip on from fourstroke works. Made vary nice, not to loud with the quite tip. I'm very happy with it.

 

I had the two brothers on mine and it sounded great. changed the maing to a 135 or 140 i cant remember now. i think i put in the the 140, and 40 on the pilot, replaced stock needle with n1tc needle on second clip and drlled venturi. no airbox lid and did the crankcase mod and removed smog crap. also changed the gear ratio. went down one in the front and i think i went up 5 in the back. these things really woke the bike up and if u are new u will notice these are the tipical mods. I sold my klx when i got my street bike and i wish i would have kept it. it was a blast.

 

I wonder how many threads are in our forum about exhaust systems and what fits ????
Search functions do work very well when used.

 

I agree, there is a wealth of information on this site regarding exhaust options, both manufactured and "hybrids". Most of it boils down to how much you want to spend and how much much "horse power" you want -but everything I've seen, seems to indicate that the HP gains between each of the options is not significant. I went middle of the road with an HMF slip on with the quiet core insert (Total $250 + shipping) and more than anything, it sounds great! This combined with the required jet/ carb changes make the KLX a real nice bike.

 

How much louder is it than stock? Does it have that low frequency tone "bark" to it that carries long distances and you can hear through walls and stuff? When you crack it open does it have that ear deafening cracking like some exhausts?

It is loudest without the QC insert -too loud for me. But the level is reasonable with the QC insert, which the factory indicates doesn't significantly impact the performance.
I will be getting sound level readings for the stock VS the HMF with and without the QC insert -just have not had the time -I had hoped to do it labor day weekend, but instead went to camp in the Adirondacks.
I promise to post the levels, which I'm doing to a test standard for comparision - there is a specific distance, angle and RPM.
I may be get a chance to bring my bike to work Thursday to get the numbers.
