I added a qsc clutch kit to my 570 which woke it up a bit but I was looking for more power... installed the evo u full system and big gun power box tuner and all I can say is wow this thing sounds awesome. YES ITS LOUD! I can keep up with sport quads all day long... it will easily wheelie in high gear.. keep up the great work big gun!

When my Scrambler starts heads turn and powerful

I had no idea my non running bike had the best exhaust money can buy
. When I finally cranked up my bike I couldn't believe the powerful sound and when I Nail the throttle , smoke billows off the tires one the road & all the power in sand

I will never go back to normal silencers again

Best purchase ever

i put this exhaust on my 08 brute force 750. it was a night and day difference in sound and as well as performance.. if you want an exhaust that will boost your performance and sound good and not be to loud i would reccommend this one.

Great system

purchased this system for 08 sportsman 800 because it sounded bad to the bone on my friends sportsman. received system and it was defective and would not slide together. big gun tech support is the worst it could be! they wanted to repair the new system and have me ship it to them.lol. they would not even send the correct replacement parts. thanks to motosport they returned the defective system inspected new system before shipping and installation went well. i still highly recommend this system. installed big gun tunner box excellent snapy power and deep powerfull tone.

A: It is not required but anytime you modify the exhaust or intake it is a good idea to remap the computer and the Big gun TFI Power box is great way to do that.

A: Yes. You should always properly tune your bike after getting an aftermarket exhaust to allow it to run at its optimal level and give you the most performance. Failure to properly tune your bike will void your warranty.

A: We're sorry, this product does not fit the ATV you selected. For the 07 TRX420 Honda, Big Gun only list slip on products.

Normally when installing a slip-on only minor changes to the air/fuel ratio are needed, if any at all. If your bike is currently running properly, likely you will not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the machine to see how it is running then decide if you need an purchase an aftermarket EFI tuner .
