Upgrade the exhaust performance of your Yamaha TT-R125 or TT-R125LE with the FMF Powercore 4 S/A Complete Exhaust, manufacturer part number 044136 and vendor part number 79-5416. Designed as a complete replacement exhaust system, this FMF Powercore 4 assembly uses a high-flow core with increased surface area to absorb more sound while allowing exhaust gases to flow efficiently.
The system features an extruded aluminum canister, a stainless steel mid-pipe with MIG/TIG-welded construction, and advanced internal packing. Compared with the stock exhaust, the FMF Powercore 4 is lighter, stronger, and designed to support improved engine performance. The integrated stainless steel spark arrestor screen is approved by the U.S. Forest Service and provides maintenance-free operation for responsible off-road use.
Fitment includes 2000-2003 Yamaha TT-R125 models and 2003-2008 Yamaha TT-R125LE models. This exhaust is intended for riders seeking a durable, performance-oriented replacement that maintains compatibility with the original motorcycle application.
