In this How To installment, we're going to be mounting our S&S 2-into-1 Sidewinder Exhaust on our brand-new Milwaukee-Eight Road Glide.

Here's the tools you'll need:

Needle Nose pliers

Flat-head screwdriver

3/16" Allen

Torque wrench

3/8" ratchet with a six-inch and three-inch extension

7/8" deep-well socket

15 millimeter deep-well socket

9/16" deep-well socket

1/2" deep-well socket

Standard 1/2" socket and a swivel

1/4" ratchet with a six-inch extension

5/16" socket

1/2" wrench

The first thing we need to do is get our saddlebags off. We'll get the muffler clamps loose and pull our mufflers off the bike.

The next thing we're going to do is loosen our crossover pipe underneath and we're going to pull our floorboard off up front. There's going to be two screws and a bracket in the back of the oil pan that we're going to need to put back in when we're done removing the crossover.

Crossover's off, our bracket's removed, we made sure to put our two Allen bolts back into the transmission pan, so we're going to move up here and take off our floorboard.

Now we'll go ahead and loosen our flange nuts on our exhaust ports. Before we pull the header all the way off, we're going to need to have a 1/2-inch wrench handy because we're going to take out our O2 sensors before we pull the header all the way off the bike. You want to make sure you save the flange nuts. You're going to need to reuse them to install the new exhaust. We're going to pull the header off now and take our O2 sensors out.

The next thing we're going to need to do is take these clips off (3:20) and remove our flanges to use on the new exhaust. With our old exhaust completely off, we have the new Sidewinder exhaust laying out in front of us on the table. There are a few things we have to do to prep it to get it ready to put on the bike. The first thing we're going to do is install our bushings for our O2 sensors, re-install our flange clamps and our clamp to hold it to the bike. Then we're going to put our heat shields on. We'll start with the O2 bushings. If you're going to use a wide-band O2 sensor, you can use the holes that are already in the pipe. Those 18 mills are perfect for a wide-band set-up if you're using some sort of closed-loop or hot rod fuel-injection controller. If you're going to use the stock O2 sensors, we're going to use these bushings they supplied in our kit here. Go ahead and put them in, tighten them up, and our stock O2 sensors will slide right in.

The next thing we're going to do is to loosely put our support clamp on this bottom header pipe here (4:43). This is what's going to hold our pipe tight to the bike. We don't want to tighten it up, just loosely install it.

We have it loosely on the header and you can see the angled portion is facing forward so it'll line up with our mount on the engine case. The next thing we're going to want to do is install the flanges off our stock exhaust. You're going to want to make sure this smooth portion is facing down. There's a little bit of a groove in this top one (5:21). That's where the clip's going to sit. With the smooth part facing down, put the clip on over the top of it. That's what'll hold your exhaust to the head.

All right, so the next thing we're going to do is put our heat shields on the pipe. We're not going to put them on tight, we're just going to keep them on there nice and loose. We want to refer to the instructions to make sure we face our clamps in the proper direction. Otherwise, when you get the pipe in the bike, you're going to have a very difficult time tightening up the heat shield once they're on. We'll thread these so the screw heads are facing down so we can access them. The one thing I like to do once get them fed through there is put a little bit of a bend in here (5:59). That way when you go to put them together, they go together a little easier.

So we've got our heat shields around the header pipe, flanges are on, O2 sensor bushings are in. Now we're going to head over to the bike and get the header pipe bolted up to the bike. Once you get the header at the bike put the O2 sensors in the pipes and put the pipes on the heads. We're going to make sure we put the rear one on first and pull the front one around without damaging the exhaust gaskets. Then loosely tighten up the flange nuts.

After getting the flange nuts loosely on there, grab the muffler, slide it on and tighten up the bolts there before moving back and tightening up the rest of the exhaust system. We slid the clamp onto our muffler. Now we're going to slide the muffler onto the header and then we're going to go ahead and tighten up our two rear screws before we do anything else.

We're going to torque the flange nuts to 120 inch-pounds. We're going to torque the side clamp to 16 foot-pounds.

All right, we'll move down. We'll torque our clamp on the muffler to 42 foot-pounds. Then we'll finish up with the heat shield. Once everything's bolted on solid, we're going to put on the collector heat shield and then go ahead and tighten the rest of our heat shield up, wipe her down and fire it up. We're going to make sure we have our clamp facing down so we can get to it from the bottom. Then we're going to take these two tabs here (9:39), slide them underneath our two heat shields here (9:41), and then tighten this up. Then we'll go on and tighten the rest of our heat shields after we have this set.

Once the heat shields are tight, we're going to go ahead and remount our floorboard. We're going to make sure to wipe our exhaust down really well before we start it so we don't burn any fingerprints into it. After getting the bags back on, we'll go ahead and listen to this sweet pipe. Bag's back on, pipes wiped down, let's hear some of this American-made horsepower.
