Hey all, hope I’m not repeating a topic already covered, but I just got a 19 KLX 250. Love the bike but hate the sewing machine sound! So far, I can’t seem to find any manufacturer’s site that has an aftermarket exhaust for the bike. 95% off-road riding and would love to up the low end pull...any recommendations?

 

Here ya go https://barkersexhaust.com/products/...exhaust-system Finding an exhaust system's not the problem. Getting the right fuel mapping that's a problem. There's been more discussion on that subject from this board https://advrider.com/f/threads/klx-2...t-gen.1266838/ than here.

 

Thanks Noob! I’ll check them out after work.

 

the stock exhaust is pretty good for low end, not much to be gained there

yoshimura has a good option too, has a nice bark without being too much. can keep your o2 sensor and fine with stock mapping

Rfeso thanks! But I’m doing a lot of ridin on Forrest service roads and have to use spark arrestor and I am on paved roads sometimes too. Would love just a slip on but I don’t see one out there yet. I’ll definitly change the gearing...much rather have the bottom end than top end most of the time. Also, still in the break in so I really don’t know how it runs in the higher r’s yet.

 

Howdy WVRider, where are you located? I live in Oak Hill and we have a single wide trailer on wife's property between Summersville and Craigsville. I leave from the trailer and can get to Monongahela National Forest in about 10 minutes of two lane. I wonder if the new KLX300 exhaust has a spark arrestor. I have a Four Stroke Works exhaust with spark arrestor. The guy that makes them is getting on in years and I don't know if he would make one with an O2 bung...

 

I put on a two brothers exhaust. Has the input for o2 sensor. Leave the decibel killer in if you don't want it to be obnoxiously loud. They also have quieter aftermarket dB killers. I've seen other people using the FMF options
