Honda CRF300F FOCO Full Exhaust System

Honda CRF300F FOCO Full Exhaust System

We discovered the FOCO brand exhaust systems on a test ride with some of our suppliers.  We were very impressed with the performance and also the lower sound level plus the super high quality fit and finish.  Amazingly, this exhaust system sounds awesome, but is not obnoxiously loud like most other open full exhausts can be.  The Foco F2 system is very affordable and offers a clear upgrade in engine performance with about a 10% increase in power. 

Lighter than stock as well!  Saves over 1.5 lbs. as compared to the OEM exhaust system!  More power, better sound, and less weight - what's not to like?!!

FOCO offers this exhaust system as specifically for the CRF300F, it will not fit the 250F and with good reason.  The 300F has 20% larger displacement and flows that much more volume of air thru it on every stroke.  Some name-brand manufacturers are offering 300F exhausts, but if you look closely their part number is the same as the 250F version or the system is very close in size.  Those brands are leaving power on the table and will not be able to match the power and torque that the FOCO system offers using tuned length headers and larger diameter pipes, resonators, and mufflers as compared with the 250F system.  The evidence is clear - FOCO takes the time to build a very nice system for every bike out there and doesn't just restamp something for a 250F as to now fit the 300F and call it good.  Beware of imitators - buy FOCO!

The Foco system also incorporates a unique resonance chamber that helps with the low to mid-range performance and also does double duty to help quiet it down.  The FOCO exhaust offers a very nice tone along with excellent performance and comes highly recommended by our HyperLite Crew!   If you are looking for an affordable, high quality, performance exhaust system, - this is your exhaust!!
