I just received the HMF 2010 Competition Series pipe. When I received the box it was in perfect condition, and upon opening the box I found that HMF actually spends time packing the box. It was carefully wrapped and secured so there was no movement. From first glance you can tell the superior craftsmanship, beautiful welds and sealing job. This pipe looks flawless. From the extremely shiny end cap to the nice black powder coat on the canister, this pipe looks like a work of art. Included with the pipe were 2 different end pieces. I thought this was really cool. Other companies force you to spend additional money on pieces to lower the db output. HMF gives you three different sound level options with the purchase of the pipe. Additional hardware for mounting was also included.
Installation was pretty straight forward. Since I just got the slip on I left my head pipe attached to the motor. The HMF midpipe slid very nicely over the existing head pipe. HMF also included a very nice and sturdy clamp to secure the mid pipe to the head pipe. When mounting the silencer I had to use stock hardware for the mounting bracket on the mid pipe. Worked beautifully with no headache. The bracket that is on the pipe lined up perfect with the mounting point on the frame. The bracket on the canister was a bit more tricky. I had to use the longer bolt and spacer that HMF supplied. I had to really force the pipe towards the frame to get the pipe close to the bracket. Once I got the pipe fully mounted I was impressed on the tight fit and the look it added to my TRX450R compared to my previous aftermarket pipe.

hen I first fired up the quad after installation I was stoked to hear the deep, throaty rumble that HMF pipes are known for. When I stabbed the throttle it is an absolutely beautiful growl. I couldn’t believe the power gains over my previous 2 Brothers pipe. My first ride with it was at the local MX track. The pipe was a bit louder than my 2 Brothers pipe but the deep throaty sound was a welcoming sound. The pipe is very sharp looking, I had three people that day asking me where I had picked it up. I have this pipe pared up with a Stage 2 cam and all I can say is WOW! I had the same cam installed with my previous pipe but did not feel anything close to the same pull and power.

My overall thoughts on the HMF 2010 Competition Series are that they spent a lot of time designing this pipe. From the extreme good looks of the pipe to the mean sounding growl this pipe has it all. I was absolutely amazed at the gains my quad received from installing just the slip on. I believe that HMF created an absolute work of art with this pipe. Visit HMF Racing to order yours!
