If you've been following our YouTube channel, you've seen we just installed an SLP Cold Air Intake on our 6.2 liter Silverado. Now, we're gonna compliment that intake and make the truck sound even better by installing an SLP Catback Exhaust. This SLP Catback Exhaust is gonna be a direct fit replacement for the factory exhaust. With its 3 inch mandrel bent stainless steel pipes and 4 inch polished tip, it's gonna make our Silverado look, perform, and sound great. There's a straight through muffler design, and 2 different front pipes that can be cut to fit any cab and bed configuration. Today, we're going to be installing it on our 2017 6.2 liter Silverado.

For this installation, you'll need a lift or a jack and jack stands, a 3/8 ratchet, 13 millimeter socket, 15 millimeter socket, torque wrench, a tape measure, and a market, a Sawzall, file, and safety glasses.

The very first thing we have to do is get our wheel base measurements so we know which front pipe to use. Grab yourself a tape measure and measure from the center of the front hub to the center of the rear hub, and get your measurement. In our case, it's 143 1/2 inches, and now we know which front pipe to use. Remove the factory exhaust, and there's only one exhaust clamp holding it on. It has a 13 millimeter bolt on it. Under the clamp, securing the Catback exhaust to the catalytic converter. There's 4 rubber exhaust hangers holding in the exhaust. All we have to do is remove it from those 4 hangers, and then the whole exhaust can come out as one piece. With all the hangers off, you can now remove the exhaust from the truck.

We can now begin installing the SLP Catback exhaust by installing the over-axle pipe. Install it into the 3 factory hangers. Install the provided 3 inch clamp onto the inlet of the over-axle pipe. Then, install the muffler. Tighten up the clamp to keep the muffler in place. We need to use the larger front pipe since our truck is 143 1/2 inches in wheel base. We're gonna line it up, and we do have to make a cut on this. Put the pipe all the way up against the catalytic converter and then we have to make sure this pipe can go 2 1/2 inches into the muffler. We're gonna make a mark right about here, so this pipe's gonna be able to go 2 1/2 inches into the muffler. We're gonna shorten it. Now, we're gonna cut right along this line. Now, we're gonna get a file and deburr the pipe to make it nice and smooth.

Install the very large clamp that was provided over the catalytic converter and a 3 inch clamp over the muffler. Install the front pipe. Slide it forward and then slide it into the muffler. Connect it to the catalytic converter. Tighten up the clamp. Tighten up the muffler clamp. Put a 3 inch exhaust clamp over the tailpipe, and install the SLP polished tip. Slide the clamp over the tip, and get the tip to where you like it. Make sure it looks good. Then, you can tighten down the clamp. Now, you can check to see if the tip moved and adjust it as needed. Now, we're gonna torque all the clamps to 30 newton meters.

Your installation's finished. Now, we can see how it sounds. All right. This exhaust is significantly louder than the factory exhaust, which, in my opinion, is a good thing. At idle it's not super loud, but you can definitely hear it back there. It sounds really good. Can't wait to get on it right here to see what it sounds like under load. All right. Now, that's what a truck should sound like. 6.2 liters of power for you. That sounded really good. Way better than the factory exhaust. This thing was way, way too quiet from the factory. Nice and quiet in idle, but you can still hear it. It's really nice. Sounded really good under load.

Let's see what it sounds like under cruising speed. See if there's any drone. Wow. No. Right now, we're cruising right about 55, and it's at 1400, 1300 RPM. You can't even tell there's an aftermarket exhaust back there. It is virtually silent. You can drive this thing across country, on your commute to work, and it's not gonna kill your ears at all. You're not gonna get a headache from it.

Definitely not gonna get a ticket for being too loud. It's loud when you want to hear it when you're under load, but when you're cruising you can't even hear it. At idle, you can just barely hear it. It's a really nice combination. Ready? Here we go. Yeah. Sounds so good. Now, this truck sounds just like a truck should sound. This is an excellent exhaust for this truck.

Our SLP exhaust is installed. As expected, it looks and sounds great. This is probably one of the easier exhausts I've installed. Installation should take about 30 to 45 minutes. Before you know it, you'll be heading down the road.
