The FMF 041249 Q4 Slip-On Muffler is an exhaust component designed for Honda CRF250R and CRF250X motorcycles, using a twin-stage core to manage exhaust sound while supporting engine performance, reduced system mass, and a practical power-to-weight ratio for off-road riding applications.
FMF identifies the Q4 series as being developed through championship off-road racing, with engineering focused on locating internal baffles and chambers for controlled sound absorption; the construction material and country of manufacture are not specified in the provided product data.
The package includes one FMF Q4 Slip-On Muffler with a built-in spark arrestor, while the supplied product information does not identify additional hardware, mounting components, or installation accessories; verify the contents of the package and compare the existing exhaust configuration before installation.
