Review & Install Video
Hey, guys. Stephanie with www.americanmuscle.com, here with the review of the SLP High-Flow Catalytic Converter Kit, from 1996 to 2010 Mustangs. In this video, we're gonna talk about the materials and construction of these cats, and the install as well. I'll talk more about the install shortly, but I can tell you right now, that I'm gonna call this a two out of three wrenches in the difficulty meter because you will need to make modifications to get these installed. You should check out the SLP High-Flow Cats if you're looking for a two-and-a-half inch stainless steel Cat for a naturally aspirated setup because you're trying to abide by emissions laws. But you still wanna ditch the very restrictive factory cats, for something that's gonna open up volume, and a little bit more power from the exhaust.These high flow cats offer a good compromise between staying legal, and still having a great sounding Mustang. You also might wanna check these out if you have an off-road setup on your car currently, but you're looking to tone down the volume or the rasp a little bit. This SLP kit has two Universal, two-and-a-half inch cats that are stainless steel, with an internal ceramic substrate material. This makes these cats perfect for naturally aspirated builds. If you don't have a naturally aspirated setup, I would recommend checking out some of the other options since there is a set of cats with a metallic substrate material, for the force induction carbs.SLP claims that these will pass most emissions tests, but what I would say is that I never promise all high flow cats pass all state emissions tests. That's honestly just the name of the game, and I can't really guarantee something like that, unfortunately. I will say, though, that if you don't feel like swapping out your exhaust when you have your emissions and inspection, then there's no reason not to try these. When it comes to price, you can expect to pay just under $200 for this kit. It's the least expensive option on the site, although the pipes offered for NA cars is only about $25 more. When you're shopping for cats for force induction carbs, the things get a little bit more expensive, because you need a different material inside of the cat to handle a higher exhaust temp for those builds. When it comes to the install, depending on how you install these, you can expect to spend a few hours, and it's gonna be a two out of three wrenches in the difficulty meter because you will need to make some modifications in order to get these installed. What exactly you need to modify will change depending on if you're cutting out old cats and replacing them with these, or if you're adding these to an off-road system. But either way, it's not a terribly difficult install. You're gonna need a good socket set. Something to cut the exhaust with like a Sawzall with a fresh blade, and a jack and jack stands or a lift to get the car in the air. If you're replacing cats with these, you'll already have your location marked for you, and you can proceed. If you're putting these into an off-road system, you need to mark and cut the mid-pipe to make room for the cats. I would then file the pipe down to make it smooth after cutting. The cats do have a specific inlet and outlet side, so you wanna make sure that you have the orientation correct before installing. And you can clamp these into place or weld them in. It's up to you. Wrapping things up here with the SLP High-Flow Catalytic Converter Kit, this is a kit that offers two Universal, two-and-a-half inches stainless steel High-Flow cats, for naturally aspirated applications. These are gonna help you keep your Mustang loud, or help you tone down an off-road setup, and you can check them out more online right here, at www.americanmuscle.com.
