I was thinkin bout puttin this on my rancher 420 but one of my friends sed it wasnt really a major difference on his 420, i have hmf pipe and uni airfilter and a snorkel kit, id be buyin one but ive heard lame reviews and its expensive for somethin that really wont be a big upgrade in power

@hyfrSilaz71 We suggest the Optimizer only for machines running an open or free flow air box. If you intend on leaving the air box lid on it is likely that you will not need an Optimizer.

Does the optimizer come with the exhaust when you buy it and do you need an optimizer if it is a slip-on? Thanks.

@19mudbogger98 The Optimizer is sold separately.

i bought a hmf sport series slip-on for my 2007 raptor 700R SE and was thinking about getting this optimizer unit.... my question is when i order it for a 07 raptor 700 will it already be pre-set to the recommended 4-4-5 settings?... and can i also reprogram it while im driving ?

thx !!

[HMFengineering]

@goldcivic21 All HMF Optimizers come pre-programmed with the proper settings, so yes you'd be able to plug it right in and take off. You can make changes while you're riding, but you'll have to have be off the machine.

[HMFengineering]

@TINACAZ Your HMF Optimizer will come pre-programmed for your machine. If you are having issues with these settings, you can always contact us directly. We have our Recommended Settings on our website. Search "Honda Rancher 420", and on the exhaust's page, Click on the "Jetting" tab.
