Upgrade the exhaust performance of your compatible Kawasaki trail bike with the FMF Factory 4.1 Mini slip-on muffler, manufacturer part number 042383 and vendor part number 79-42383. This tuned exhaust system is designed for the 2008 Kawasaki KLX140 and 2008 Kawasaki KLX140L, as well as select KLX140 models from 2009 and 2011 through 2017. The system combines a stainless steel construction with an anodized titanium canister and includes an FMF Titanium Megabomb header designed to help optimize power output for each application.
The FMF Factory 4.1 Mini uses advanced Resonance Chamber Technology to help reduce exhaust sound while preserving strong performance. Its patented core shape maintains maximum power output, while the canister design provides additional internal volume for sound-absorbing material. A patented chamber design refines exhaust pressure, helping deliver a responsive powerband suited to off-road riding and trail use.
Factory Forward Engineering centralizes the exhaust mass and helps reduce exposure to crash damage. The innovative rear end cap allows straightforward installation of tuning tip inserts or a spark arrestor, providing flexibility for different riding environments and requirements. The included Titanium Megabomb is tuned to complement the exhaust system and help maximize the performance potential of the compatible Kawasaki engine.
