I’ll be posting write-ups here on all my modifications. This will be a good place to store information on mods and how they’re installed if I ever decide to sell the quad.
I’ve always loved modifying vehicles and atvs aren’t an exception. With a huge aftermarket and parts not costing a fortune, atvs are amongst the funnest vehicles to modify.
Here is a list of current modifications :
2015 sportsman 850 SP
-Big gun eco system exhaust
-ATV guru front and rear bumpers, powder coated orange
-Vivid Light bars 10" single row "K" series light bar, 5w cree LEDs, spot pattern
-custom painted tail lights
Future modifcations
-Orange powder coated handlebars. Finished but need to be installed
-Tusk heated hand grips/thumb lever heater
-custom Morimoto matchbox bi-xenon projector retrofit
-full underbody aluminum skid plates
-high clearance lower A-Arms
-warn 2500 lb. winch
-HMF optimizer
-K&N air filter/filter wrap
-amplified blue tooth speaker tube on front rack
-Polaris Interactive Digital Display
-Rear rack storage box with built in cooler
That’s about it! I’ll post my current mods and walk throughs for each in case anyone is on the fence.
*Big Gun Eco System exhaust*
The factory exhaust is held on with springs and mount to rubber bushings in the frame on the back of the quad. Using a hook tool or needle nose plyers will allow you to have the stock exhaust off in seconds. Next, you’ll need to attach the bolts to the mounts of the big gun exhaust. The head of the bolt needs to be on the right side of each mount. Simply slide the bolts through the rubber mounts similar to the way the stock exhaust mounts up and use the springs to attach the exhaust system to the lead pipe. Now, you need to decide on your tip set-up. There are 4 ways to run it.
1. Straight through
2. Quiet core only
3. Spark arrestor only
4. Spark arrestor and quiet core
With mine being the cheapest, running the quiet core and spark arrestor didn’t work at first. The Quiet core rattled a bit. Big gun sent me a few of the rings they use to make the spark arrestors to use as shims. It only took one between the quiet core and spark arrestor. That’s it! 5 minutes and you’ve got an ATV that sounds better than most cars With exhaust do!!

*ATV guru front and rear bumpers*
Luckily, ATV Guru makes it simple to install front and rear bumpers. I ordered mine bare and had them powder coated Orange to match the shocks. The rear bumper is the easiest. Remove 2 star head bolts from the rear rack, place the rear bumper on the atv, replace the star head bolts and slide the included bolts through the bottom mounts. Simple
Front was not so easy. After dealing with stripped threads and a few other things, I ended up with grade 8 hardware. Remove the 4 bolts from the front bumper. Pull out the 4 stock nuts that sit in the frame and replace them with higher quality bolts. Slide the long 5 1/2" bolts through the bumper. Start from the bottom. Start just the 2 bottom bolts first, then, Start the top one’s. I found that doing a cross pattern when tightening really helped the process. After that, you’re done!
*10" single row light bar*
Use a dremel to oval out the light bar mounts for adjustability. My light bar was slightly too long to line up with the mounts welded to the bumper. I ovaled out the mounts on the bottom. Slide the bolts in and you’re good
Wiring. The harness that came with it is simple. Remove plastic from headlight pod and below the handlebars. Remove front rack. I mounted the relay on the right side of the ATV
The positive and ground wires with the terminal are perfect length. Put those Next to the terminals. Don’t attach them yet, you’re not done. Measure enough wire to reach the gauge pod. Cut the switch wiring and strip the leads. Slide on and crimp female spade connectors. Drill a hole, mount the switch and check polarity. Attach the wires. Measure the wiring going to the light bar cut about 4" up from the deutsch connector on the harness. Determine where to shorten it and how much. Solder, heat shrink and seal the joint up well. Connect the battery terminals and the deutsch connectors and you’re done.
*Tail light painting*
I noticed the tail lights have a ring built in and wanted to accentuate them. I had round stickers made to mask the area I didn’t want painted. 3 coats of ford ebony black and 3 coats of clear. Wet sand and buff to finish up.

Finished
The specs on the stickers are 3" diameter and a 1.5" inner diameter perfect circle.
