      Review & Installation Video

      MBRP's Muffler Delete should appeal to the S197 GT owners out there, looking to really crank up the volume with a rather affordable muffler delete system, but more importantly one that will deliver that all-back unique finish or look. Now, your pricing will hover right around that $300 mark, and it's gonna get a simple one out of three wrenches on the difficulty meter from me when it comes time to talk about that install. But let's start out with the most important thing with any exhaust review, and that of course is the sound you can expect when bolting up this system. And to put it bluntly, guys, the MBRP Muffler Deleting Axle-Back sounds mean. A lot of volume, tons of pops and backfires coming down off the revs, but maybe one of my favorite parts about this system is just that nice, deep-thumping tone, just a really gnarly sounding system overall. Going to my patented and tried-and-true, wake-the-neighbors scale, I have this thing waking up a lot of neighbors at a strong four out of five on my one to five or one to wake-the-neighbors scale. Now, keep in mind this is still with those factory manifolds still in place in the cats of course. Remove those paperweights in favor of some shiny aftermarket goodies, and prepare to reach volume levels previously unheard. I did want to point out that we heard this thing a little bit inside the car, but any time you go this aggressive with your exhaust, you're bound to hear a little something inside and that certainly was the case here at the MBRP. A little bit of drone in the usual problem areas between 2000 and 3000 RPM while cruising on the highway, but at the end of the day, if you're shopping for something this aggressive, something tells me you're not gonna be bothered by a little bit of interior noise. But, how does the MBRP get its loud and super aggressive tone? Well, it's pretty obvious, right? Take a look at this thing. You're essentially replacing the factory muffler, or any muffler for that matter, with a straight pipe, giving you that loud and rough-around-the-edges sound, those pops, those backfires that we heard coming down off the revs which, by the way, always gets the nod of approval from me. Construction-wise, well, very simple here as well, as you would imagine with any muffler deleting axle-back. Three-inch Mandrel bent tubing essentially from tip to tip, everything's gonna dump out of your 4-inch slash cut tips etched that MBRP logo. But maybe the most important thing with this system is that all-black powder coat, giving it a very stealthy look. And it is actually gonna add some protection as well to that aluminized steel construction, which otherwise might be a little more prone to corrosion over the years, whereas that powder coat with help protect it over the years on your Mustang. But, something to keep in mind here, guys, if you love everything about this system, from a sound perspective, maybe you're just not too crazy about that all-black look, or the aluminized steel material, MBRP does offer a full stainless version of this muffler deleting axle-back on the site. Believe it or not, it's actually a little bit more affordable than the black option that we have here, and it is something to consider if you're interested in this system. Now, even though the $300 price tag might seem a tad steep, given the simplicity of the system here, you have to keep in mind the MBRP is the second most affordable muffler deleting axle-back on this site. Only the Heartthrob will be a little bit more affordable, but you have to keep in mind, like the MBRP, that Heartthrob is also made from aluminized steel. However the Heartthrob is not going to deliver that all-black powder coating, so you're not getting that corrosion resistance, you're also not getting that unique look. So you have to consider that into the price as well. Now, as I mentioned earlier, axle-back installs on the S197 are a complete piece of cake, even for the novice wrenchers out there. So I'm sticking with one out of three wrenches on my overall scale of difficulty, and anywhere from 30 minutes to an hour, depending on your setup and depending on your expertise. Tool wise, well, basic socket set's gonna be doing most of your work here. Also helpful to get the car in the air, whether it be through a jack and jack stands, lift or race ramps, totally your call. Last, but not least, I always like to recommend a little spray lubricant for an exhaust install, not only to help you with some rusty bolts but also to give you some help with those rubber exhaust hangers. You're gonna wanna start by removing those factory cans. Go ahead and grab your socket set, remove that clamp closest to the muffler, in addition to a few bolts on the hanger, allowing you to drop the muffler from the car. Now you can transfer that hanger over to the new MBRP system and lift it into place, securing it to the car with a few bolts at the hanger, in addition to that clamp you removed in the very first step. But don't overtighten these bolts quite yet, because you will need to leave them loose to make some small adjustments, getting that tip exactly where you want it. Once you have that tip exactly in place, either you or a buddy, hold it in place while you tighten up all your bolts, and your installation is complete. So, if you guys are looking for a loud and aggressive system for right around $300, with the added bonus of that all-black finish, you'll wanna check out the MBRP Muffler Deleting Axle-Back right here at

      This says it wont fit my 2013 Boss, I thought it would be the same as a 2013 gt? Is this true?

      Hey I Have A 2012 Mustang Gt 5.0 an was wondering What’s louder the SLP Loud mouth Axle- Back Exhaust or the MBRP 3 In Axle-Back exhaust? An Also What Is Better to pair with (the louder axle-back) an X pipe or an H pipe ? Looking for the loudest/ best sound I can get

      I currently have the pypes pype bombs on my 2012 5.0. Has anyone compared the pype bombs vs this product? I also have the pypes off road x pipe installed with an air MXP series CAI and she's tuned by BAMA. Anyone have any thoughts or if the swap is worth it?

      • The MBRP muffler delete will be more raspy and louder than the Pype bombs.
