Polaris Sportsman 450 / 570 Performance Tune with DynoJet PV3 Tuner
Duane X.
Rating: 5/5
Sounds great, solid build
Needed a fix for my rig and this did the trick. Sound is deep without being obnoxious. Noticeable pull up top after installing. Glad I made the switch.

Sounds great, solid build
Needed a fix for my UTV and this did the trick. Bolt-on install, no tuning needed. Does the job, though the instructions could've been a little clearer.

Grabbed this after my old one wore out. Bolt-on install, no tuning needed. Sound is deep without being obnoxious. Glad I made the switch.

Sounds great, solid build
Ordered the polaris sportsman 450 / 570 performance tune with dynojet pv3 tuner last month and finally got it installed. Works, but not quite as sturdy as I was hoping for the price.
