Updated review: this does fit my klx 140L after calling FMF and getting install instructions

The media could not be loaded.  This exhaust sounds so much better than the stock one on my KLX140rL. Expected 5 days to receive but got it in 2. Took only 15 minutes to change it.

The media could not be loaded.  My buddy laughed because my bike was so quiet but not now with the set up I'm putting together this works beautifully

Put this on my son’s KLX140 and it sounds great. Very easy to install and I can tell a difference in low-mid power too when I’m messing around on it - even more so for him. Definitely a good purchase.
