Bought the full system for my 2014 trx450r and it does perfect, with a new air filter and jet kit it really brought it too life, tons more torque and sounds amazing! Very loud! Perfect.

Have this hmf pipe on my 400ex. This pipe has a nice deep tone and and really opens your quad. My 400 is SUPER loud and really throaty and snappy.
I got this for my 2013 Honda trx450er and as soon as I took it for a rip I felt a huge difference in power im done using fmf I think im gonna use hmf from now on I would defiantly recommend this to anyone.
I picked this pipe up on recommendation from a friend, and with the custom jetting and uni filter, and lack of air box lid this thing screams. I love it, but would not recommend it to anyone that doesn't want to be loud. the pipe is legal for trails, but is definately pushing the limit.
i bought this exhaust from a different site becouse i got it in a candy blue powder coat for my ltz 400. but this is a awsome exhaust before i got this i could barley get a wheelie going in second now i can get a wheelie going in 3rd and even 4th if i pull realy realy hard. it added alot of speed and hp. i put the quiet core in it and its still loud but now legal on trail and sounds awsome. 100% happy with the outcome

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.
The competition exhaust will come one way, black can – euro polish tip and it will come with 3 racing inserts. On a few models you can choose between elliptical muffler and round. The Competition Exhaust features a special tri-max core. By default, the largest of the 3 inserts (Stage 3) will be installed for the customer in the exhaust. There is no way to change the tips on a competition exhaust due to how the inserts work. They need the euro tip to make them work. The inserts are known as Stage 1, Stage 2 and Stage 3. Stage one can be run in the exhaust for the least sound and power gains on the machine. HMF installs the Stage 3 because most racers need the gains and don’t care that much about sound. The competition exhaust shines from the low to midrange but will still give gains across the power band. It is the exhaust for the rider who is competing and riding their machine hard or just the customer that wants every piece of horsepower/torque out of their machine.. I try to sell this exhaust to anyone who wants to get maximum gains on their machine. Most of our pro riders run this exhaust.
