hello, need advice, i have a 2009 klx 250s and want a muffler that will give me a little more power ,and alot more sound, i live in the country so i am not worried about the noise, but want a bolt on good quality product, i see lots of opinions here, thank you in advance!

 

Muzzy, two brothers, HMF, FMFQ4 arranged loudest to quietest (not that the Q4 is quiet). All good quality. HMF is the least expensive. click https://www.kawasakiforums.com/forum...ad.php?t=32162 to see and hear a comparison vid of 3 of those 4 pipes.

The stock KLX 300 full exhaust will bolt on too. Cheaper, and heavier than the aftemarkets, but probably about the same amount of performance gain.

I've got a Two Bros and am very happy. I like the different tip options that 2Bros offer

 

Get the HMF its the cheapest and its Loud. I love mine

 

I just put an FMF Q4 on my 2009, I would highly recommend you get a Kouba adjustable idle fuel screw and raise your needle .035 with a shim. Up until my exhaust, that was the only thing I had done. I don't know what the factory setting is, but with my new adjustable it was out at 1 3/4 turn and by adding this muffler alone I'm out at 2 1/2 now and am gonna have to buy a dynojet kit because the bike does run lean on mid/upper range. Not to the point that it's not ridable, but you can tell it's lean. I am right at sea level.
