Upgrade your motorcycle’s exhaust performance with the FMF Powercore 4 S/A Exhaust System, manufacturer part number 042002 and vendor part number 79-1522. Designed for improved exhaust flow and sound control, this system features the latest Powercore 4 design with a high-flow core that provides more surface area to absorb sound while allowing exhaust gases to move efficiently.
The FMF Powercore 4 S/A is constructed with a durable extruded aluminum canister and a stainless steel midpipe. The midpipe is MIG/TIG welded for strength and reliable service, while space-age internal packing helps manage sound and maintain performance. The system is designed to be lighter, stronger, and more powerful than the stock exhaust, making it a practical performance upgrade for trail and recreational riding.
For off-road applications, the integrated stainless steel spark arrestor screen is U.S. Forest Service approved and maintenance free. This exhaust system fits 2002–2011 Kawasaki KLX110 models and the Suzuki DR-Z110, including the 2003 model referenced in the product name. Verify your motorcycle model and year before installation to ensure proper fitment.
