Gnarly a great pipe!
" I have had this pipe for 3 years. It has taken a beating from east coast rocks and other nasty stuff. Great low end power improvement over stock. Paired it with an FMF Q to keep my KDX 200 quiet. Simple jetting change was required to get the best power. "

"As advertized"!
" Just bolted this pipe up this afternoon,(along with the Turbine Core silencer) on my 99 RM 250. The pipe does EXACTLY what it's advertized to do! Before I hit 2nd gear, I could feel the difference! This year RM was a very "pipey" bike, with all the power on the top. There is no "hit" now, it just pulls from just off idle to the top...a big "rush". I would compare it to an old 70s/early 80s open class bike in power delivery. ( I'm showing my age, but that kind of power delivery is a good thing, to me!) GREAT PIPE for what I'm doing! (Desert/single track/trails/woods/fun) Much more fun bike to ride now! "

awesome pipe
" Great additon to any bike. Spend an extra few bucks for the strength and sturdiness of the Gnarly. Installation is a breeze. Takes about 2 min. Make sure you buy a spring puller - again a few extra bucks saves you time and frustration. The best part is you keep it for life so don't be so dang cheap by improvising with other tools! "

What's to say, it's a Gnarly
" Been a Gnarly fan for years. Bought this one for my '98 KDX200. Great pipe, built like a tank and does exactly what it says it will for your low end. I ride/race tight North Carolina woods, and wouldn't ever consider using anything else. Thanks to Motosport for the great customer service and the price match. "

INSANE LOW TO MID RANGE GAIN.
" THIS WAS THE FIRST AFTERMARKET PIPE I INSTALLED ON MY KX 500, ALONG WITH THE POWER CORE SILENCER. THE PERFORMANCE GAIN WAS AWSOME. AT THAT TIME MY BIKE WAS OTHERWISE ALL STOCK BUT ALMOST UNCONTROLABLE AT BOTTOM TO MID RANGES WITH THIS SIMPLE UPGRADE. MUCH MORE INSANE THAN THE PRO CIRCUIT LINE OF PIPES. LOOKS BETTER TOO. NOTE TO KX500 RIDERS: IF YOU WANT AN INSANE MID TO TOP END PIPE, I RECOMMEND THE FMF GNARLY "DESERT PIPE" IT EXISTS. I HAVE ONE, AND IT IS AWSOME!! "

" this pipe is great. it was what my RM250 needed to get more low end power and making it easier to ride by smoothing the powerband. "

I would recommend this pipe, but...
" I put this on a 2000 CR250R three years ago. It fits well and looks good. It did give me a big power boost on the bottom, but it completely removed my top end power. I've tried larger and smaller main jets with little improvement. If you need top end power and over rev, this is not the pipe for you. The lowend power is so abrupt I installed a 10oz. flywheel weight to make it managable. "
