Hey, guys. It's Sara with americanmuscle.com. And today, we have a review and install of the Krona Performance 3-Inch Cat-Back Exhaust, fitting your '18 and newer Ford Mustang GT Fastback without the active exhaust. This exhaust will improve the overall sound and performance of your Mustang and is proudly made in the USA. This exhaust features Helmholtz sound reduction technology giving you that aggressive muscle car sound you're looking for without all that intrusive cabin noise. This exhaust is constructed from 3-inch mandrel-bent 304-stainless steel with a resonated mid-pipe and straight-through muffler design. And they finish this system off with dual 3-inch polished stainless tips featuring the Krona logo.I'm giving this exhaust a four out of five on the loudness meter. It definitely wakes up the sound of your Mustang without being too overpowering. This is for the Mustang owner who's looking to improve performance and sound over stock and also wants that distinctive muscle car growl without being overpoweringly loud. Coming in at around $1,500, this one is middle-of-the-road price-wise as far as cat-backs go. But keep in mind this is constructed from 304 and it does feature mufflers where some of the lower-priced options are 409 stainless and they feature straight-pipe design. So this exhaust is going to get you that distinctive sound you're looking for while save you some money over the higher price options.I'm giving this install a two out of three wrenches on the difficulty meter. It's gonna take approximately two hours to install, but it may take you a little bit longer to get the adjustability just right. But with that said, let's jump right into our install. For this install, we used an exhaust hanger removal tool, a rubber mallet, an impact gun, a 13-millimeter socket, a deep 15-millimeter socket, and an extension.All right, so the first step in our uninstall is to grab a 15-millimeter socket and loosen both the nuts on each of these pipes. Next up we're gonna remove these hangers from the subframe, you're gonna want a 13-millimeter socket and an extension, just gonna go right over top of the sway bar. Now you can lift up and flip these out of the way. At this point, we can separate the exhaust from these two clamps that we loosened earlier. You may want to mallet as this will make it a little bit easier to get them off.All right, now that we have our factory exhaust removed from our Mustang, we're gonna put side by side with this Krona exhaust, really check out some of the similarities and differences. Now right off the bat you may have noticed this one is quite a bit nicer, it's constructed from 304-stainless and features 3-inch piping, which is larger than the 2.5-inch of your factory. It also features straight-through muffler designs, which means you're gonna get that nice sound when compared to the factory mufflers. And they finish it off with some nice polished tips.All right, so the first step in our install is that we're gonna replace these factory clamps over the ends of the factory piping. With those in place, we're gonna put these two adapter pipes into this clamp. And we're gonna leave this loose for now and then tighten it down later. All right, next up we're gonna grab the larger clamps that come in this kit and we're gonna slide them over these adapter pipes. All right, now that we have the clamp slid over the adapter pipes, grab your resonator section, you may want a jack or pole jack to support it and slide it into your clamps.At this point, we need to remove the hangers off our factory exhaust so that we can reuse them on our new exhaust. Either slide these off by hand or if they're fighting you, you can use one of these tools to get these off. All right, this way we can slide our clamp over top of our resonator section and just leave a little space for our pipes to go in there. Now the rubber bushings can go over top of your hanger and we can get our muffler section installed. Starting with the very rearmost hanger, get that installed. And now loop this bushing and bracket right in this hole to hang there and you can work your pipe in your resonator section. Now you can repeat that on the other side.Line up the holes in the brackets that hold your isolators and replace the bolts. Grab your 13-millimeter socket and tighten these down. Now with your 15-millimeter socket, we can start tightening down the clamps starting at the ones of the very front of your exhaust. Make sure the clamps are in the tabs on your factory exhaust and these adapter pipes are all the way up against them. At this point, once the adapter section and the resonator section is lined up in this clamp, tighten these down. At this point, we can line up our muffler section with our resonator section and tighten down these clamps. And repeat that process on the other side.All right, at this point, we're gonna grab our smaller clamps and put them over the muffler section so that we can install our tips. All right, now we can install the tips. And you may need to adjust these so they fit nicely with the valence but you can always tweak that once you're completely finished. Grab your 15-millimeter socket and tighten these down. Repeat that on the other side.All right, so that is gonna do it for the review and install this Krona exhaust. Remember for all things Mustang, keep it at americanmuscle.com.
