Exhaust is really loud!! Especially when it gets wet. But to fix that just repack the muffler..... I love the exhaust nice deep sound and way better throttle response.
I didn't feel a difference in power with this pipe but it sounds great and you can hear me coming from about 2 miles away. Honda Rubicon
great sound, but did not see/ feel anymore power than before...would recommend for a honda 450 foreman 2004
great product sounds awesome highly recommend.
Lil louder than i anticipated on my 08 750 Brute Force... but sounds great and really gave a noticeable power increase and throttle response. not to mention motosport shipped and and it arrived just as they told me. very pleased about this also. As well as an easy install.
This pipe is a must have for all rancher owners. Great power, broad gains in low mid and high RPMs the sound alone will be enough to make you happy. The styling could be better. overall this pipe gets a 5 out of 5 from me
Great power, big noise.
great exhaust very easy install only complaint is that the pipe makes your bike stupid loud.
I bought this product last year in december and have just been amazed with the sound and the additional gain in horse power , and over all i would go back to HMF agin for another exhaust and would recommend this product to anyone.

Improper air fuel ratio can lead to engine and/or exhaust system damage not covered under warranty.
When used with an HMF exhaust system, your 2014 Honda Rancher 420 will require the HMF Optimizer with O2 sensor bypass. If not used, poor engine performance will occur.
