Purchased the shorty header for my 390. Quality is top notch and the pipe is definitely stronger than stock. Pared with an FMF Q4 and noticed an immediate performance gain. Would definitely recommend to anyone looking for a little extra power.

My experience with the 22 fab header has been killer! This header has been everything that it’s been claimed to be. The build quality, material and welds are excellent. The fit was perfect, it looks awesome, sounds awesome, bike has way more snap and flat out rips all the way through the rpm range better than ever. I already thought my 390 was the best woods bike I ever had, and now it’s even better. I paired it with a Q4 so I’m still quiet, but it sounds like it should now. Evan delivered super-fast and even sent out some cool stickers. Oh, and it hasn’t flamed out once since the upgrade!! But hey, if you like the wimpy-sounding restricted stock flameout header, don’t buy it.

I had my first race this past Saturday and the bike had incredible performance with the new shorty header! Snappier response and definitely more horsepower. A total benefit for my overall measured times on the FIM circuit.

I have pushed it through 3 hare hound desert races with rock gardens, sand washes, single track, rock cliffs and open road. All races over 100 miles and it has performed flawlessly. I have enjoyed the power and improved my class finishes, getting several podiums! Race proven on my 350!
