Frequently Asked Questions

Q: Is this a slip-on or a full exhaust system?
A: The FMF Mini Powercore 4 for the Yamaha TT-R125 is a full exhaust system, which includes the stainless steel mid-pipe mated to the aluminum rear canister.

Q: Does this model include a spark arrestor?
A: No, this standard model (044136) comes equipped with the Euro Hi-Flo end cap for unrestricted power. However, it is compatible with an optional screen-type spark arrestor (sold separately) if you need to ride on restricted forestry trails.

Expert Pro-Tip: When installing a new full exhaust system, always check and potentially adjust your dirt bike's carburetor jetting or fuel tuning to safely accommodate the increased exhaust flow. Apply a high-quality anti-seize compound to the header mounting bolts to prevent them from locking up or stripping out over time due to extreme heat cycles.
