Got for my 2003 cr250r and I love it fit great sounds good and is gonna work alot better then the smashed in fatty that was on it. Would have been a 5 star item except it was missing the pre welded on nutcert on the rear of the pipe where it bolt by the exhaust pipe. Other then that looks great fit great runs great.
Seems as though fmf quality isn’t what it used to be sloppy and rusty welds on a brand new pipe and Motorsport folks loosely packed it in a box with my new bike stand got a rusty scratched and dented brand new pipe looks like I’ve been running this pipe for over a year
Have used this pipe on all our bikes for years. They work great for hare scrambles and hold up well.
Awesome pipe for beefy low end torque and midrange. Still has a strong top but not as strong as fatty when compared back to back. Midrange hits stronger than fatty. Awesome pipe.
Compared to the pipe I had been using, this pipe definitely added bottom and mid-range punch. The grunt at really low rpm is very comparable to an RFS 4T, you just have to be very judicious with the throttle when searching for traction as any snap wiil breakit loose.
I also found that when re-jetting was corrected that there was little noticable loss to the top end power. Short shifting quickly through the gearbox under heavy throttle can be a near short-staining experience, so you really dont need a shreiking over-rev.
The bike is a 2013 Husaberg TE300 with an SX head and SX ignition, RB Designs carb and a 5 oz. Steahly flywheel.
Bought this to go with the RB head and carb mods, really woke the bike up, has more usable power throughout the RPM range. Sounds good too!
This FMF Gnarly gives maximum low-end boost to your stock engine.
Due to the variations that may come into effect when tuning an engine (i.e. pipes, intake, altitude, cams, displacement, standard or high compression pistons, etc.) we CANNOT offer jetting recommendations.
