So, the dB Performance by Corsa Sport Cat-back is gonna be one of the louder and deeper-sounding exhausts currently available for the 4.8 liter powered '07 to '13 Silverados. I'm happy to say that this system is made out of a very unique T-439 stainless steel which also makes it one of the most well-built.Now, sound is what matters so I can try and help you out with that. This is gonna be a strong four out of five on my loudness meter. I would say that the loudness and the tone of this exhaust would be right at the limit of what you would want if your daily drive your truck and you want something that's gonna turn heads, maybe something that'll be a bit louder than some of the other exhaust options available but something that's not going to be crazy droney inside the cab and that's all thanks to Corsa's contribution with their reflective sound cancellation technology. From experience, I'm happy to say that this is definitely one of the deeper sounding exhausts available so if you went with the 4.8 liter versus the 5.3 liter, I'll be happy to say that this actually makes the truck sound even deeper than the 5.3 motor.Now as far as built quality goes, that T-439 stainless is pretty cool. Basically, you have a couple of levels when it comes to stainless steel and exhaust and you have aluminized at the bottom, you got 409 which is your factory grade, then you got 304 at the top which is considered the best of. Now, 439 is actually about as good as 304 stainless, however, our manufacturer says that is specifically designed to handle heat and tolerances in hot and cold so you're not gonna have to worry about this thing leaking or cracking especially once it develops some corrosion.So again, if you want one of the most well-built exhausts, you want something that's made out of the unique and relatively new stainless steel, then the dB Performance should be at the top of your list. I also like this system because it installs very easily. It's a factory side exit configuration. It's not a split exit so you're not adding an extra tailpipe or any hangers. It's purely a bolt-on install. It's actually pre-measured for your cab and bed length so there's no cutting required. You don't gotta invest in any power tools or a Sawzall or anything like that. And I would say you can actually get this installed in probably an hour or two with basic hand tools. So for that reason, I'm gonna give the install very easy one out of three wrenches on my patented difficulty meter. If you like the sound of this exhaust, I'm actually gonna show you how to bolt it on here in just a second.To install your new cat-back on your Silverado, you will need the following tools: standard drive ratchet, a 10-millimeter socket, and a 14-millimeter deep socket. Optional tools include an exhaust hanger puller tool, some spray lubricant, or a cordless impact. So you can actually remove your factory exhaust as one piece. To start, you're gonna have to loosen this clamp up here directly behind the catalytic converter. We're going to be reusing that clamp later so you can actually leave it in place once you do so. But to loosen it, you're gonna need a 10-millimeter socket.All right. Now that we have that clamp loosened, all we have to do is pull our exhaust hangers from the rubber isolators on the truck itself. There are four in total, one directly in front of the muffler, two directly behind it, and one over the tailpipe. It's helpful to have an exhaust hanger puller tool or a pry bar of some sort. And it's also helpful to have some spray lubricant because it is rubber on metal. This will grease them up to make it easy to slide them off.All right. So, once you get to this last hanger on the tailpipe, you want to take your time and be careful with this because once you pull it, the exhaust will actually be free from the vehicle and it's going to want to fall down. What you're going to do after you pull this is gently let the tailpipe rest on the axle. All right, once you've got it there, you're going to push the entire exhaust system back towards the bumper, just enough to let the mid-pipe fall down past the crossmember. Once you've done so, you can pull the exhaust forward and you can actually move it out from underneath the vehicle.So now we have our factory cat-back removed, you can really see the similarities between the original and our new exhaust system. I like the similarities here in terms of the build quality because it reuses all of our factory hanger locations. It also has the same flared design on the mid-pipe which allows us to reuse our factory clamp that we loosened earlier. So overall, dB performance and Corsa make the install really easy. Again, a bolt-on application because it is pre-measured for your cab and bed length, no cutting required. That's where the similarities end. What's really cool about this exhaust system is it's actually made out of T-439 stainless which is not 409, it's not 304. Our factory exhaust is usually made out of 409 stainless and you can see it has some corrosion and some light pitting because it has seen some road salt. Again, when we're on the East Coast, we get a lot of snow. 439, they say is actually made exactly for exhaust systems. It's equivalent to 304 stainless but it actually stands up to temperature changes better. Basically what that means is even if you get a little corrosion on here, which all stainless does corrode a little bit over time, you won't have to worry about this thing cracking or developing any pinhole leaks. Basically, T-439 is a perfect steel for exhaust systems. So, Corsa and dB Performance really nail it on the head as is always the case.So without further ado, let's go ahead and start throwing on our new exhaust system. So we're going to start with our mid-pipe for our new exhaust. You're going to throw this hanger into that first rubber isolator, then you're going to throw the flared end of the mid-pipe onto your Y-pipe and we're gonna tighten down that clamp just enough to hold this in place but loose enough that it has a little bit of wobble in it. We want this thing to have some play, that way we can line everything else up before we tighten all our clamps down.All right, now that our mid-pipe is in place, we can throw our muffler on. Now the muffler is gonna have to be held up until you get the over-axle pipe in place because the over-axle pipe is what has the hangers for the rubber isolator. So, it's helpful to have either a pole jack or a friend hold this while you do so. Make sure before you throw the muffler onto the mid-pipe you have one of the clamps on the end there, that way you can secure them and tighten them down when we're all done.All right, so now that our muffler is in place and it's held at the right height, we can install our tailpipe. Now, again, because the hangers are on the tailpipe, it's kind of a pain to get the ones behind the muffler on so I recommend fitting the tailpipe onto the muffler, keeping things loose. Throw this rearmost hanger on first and then you can take your time and tackle these. Again, it's helpful to have some spray lubricant to help slide them on because it is a tight fit.All right, so now our cat-back is technically installed. All we have to do is tighten everything down. To tighten down the exhaust tip, you're gonna need a 14-millimeter socket and you're also gonna need that same 14-millimeter socket to tighten down both D-clamps. Once you've tightened everything down, it's just a matter of making sure you tighten down that clamp behind the catalytic converter and you'll be all set.So once you've got that last clamp tightened up, that'll actually wrap up our install. As you saw, it was pretty easy, pretty much a bolt-on job. And that also wraps up my review of the dB Performance by Corsa Sport Cat-back fitting your '07 to '13, 4.8 liter powered Silverado.
