I knew that HMF had released a new system and was searching around to see if any others were released yet. I have never heard of them, but "Big Gun Exhaust" has a couple different pipes out for the Wolverine and a tuning box too. There is a video on their site with sound comparisons and the EVO sounds bad ass.

EVO U Full System - Yamaha Wolverine / R-Spec / EPS (2016)

TFI Power Box - Yamaha Wolverine / R-Spec / EPS (2016)

Big gun has been around for a long time, I never had their stuff before but it looks like quality stuff.

Very nice indeed!! Good to see more aftermarket parts coming out. Just wish there was more info on the TFI box. What's it do? Does it increase rev limiter, advance ignition, come with maps for the exhaust?

That evo sure does sound loud. Wonder what it sounds like in cab while riding. Noticed it comes with a quiet insert.. hope that vid was without the insert.

Maybe it would drown out the CVT...?

Just did some reading on their TFI box. Basically, they sell it as an electronic jet kit. Just controls the fuel map for the injector.

TFI is a dobeck product and depending on which one it is, it can only add fuel not take it away and there is no ignition to it.

Never had much luck with Big Gun products, need repacked way to often and you better like using a rivit gun to do it.
