MOTO EXHAUST REVIEW: FMF RACING POWERCORE 4 & MegaBomb Header!

Contributing Editor Andre Sergoyan of Dirty Mountain Goats (his YT channel) bolts on an FMF Racing Powercore 4 slip-on exhaust, pairing it up with am FMF MegaBomb Header. Did this exhaust combo yield the power delivery & performance that he was looking for from his 2016 Yamaha YZ250FX? Watch the video to hear his observations and his bottom-line while riding the Pac NW mountain trails.

My Megabomb/Powercore combo is awesome. The most improvement I noticed was the aftermarket airfilter and Fuel Controller. The exhaust added a little more torque, and got rid of the jerkiness of the stock system. And you are right about you cant beat the throatiness of a decent exhaust. Nice vid dude. Cheers
