Show original supplier description
The FMF Mini Powercore 4 muffler is engineered to provide a significant performance upgrade for your mini bike, offering the "best bang for your buck." This slip-on system is designed for "Closed Course Use Only" and features a Hi-Flo stainless steel core with formed end caps. The construction includes an aircraft-grade aluminum canister and a durable stainless steel header. Weighing in at just 2.4 lbs, this muffler is considerably lighter than the stock unit, contributing to improved handling and responsiveness. Users can expect to feel an "overall increase in power and torque" from the first twist of the throttle, making the motor feel as if it has been bored and stroked. This model, part number 041582, includes an internal spark arrestor. It is constructed with durable stainless steel and aluminum components for longevity. The muffler is specifically designed for the Honda CRF125F and CRF125F Big Wheel models from 2019 to 2027 (CRF125F) and 2019 to 2024 (CRF125F Big Wheel).
