      Review & Installation Video

      Ford Performance's Bullit Axle-Back that I've got here today is gonna be a good option for any of my 4.6 or 5.4 owners out there looking to improve their exhaust note ever so slightly, not getting too loud, not picking up any drone, last but not least, for someone that's after Ford Performance's legendary build quality and attention to detail. Now any axle-back for this generation of Mustang simply bolts on, and for that you're gonna be looking at a very easy one outta three wrenches on our difficulty meter here, about an hour job, and I'll show you how coming up soon.Okay, so right outta the box what you just heard is definitely gonna be on the quieter side of the spectrum here, and this is easily gonna be catching a soft two outta five in the wake the neighbor scale here, and it's really easy to understand why. Now this quieter axle-back is still a decent improvement over the factory mufflers. Those stoppers really just don't do the three valve too much justice. And let's face facts here, guys, it pretty much just makes it sound like any other V8 on the road. So if you're the owner that likes that relative volume of your stock system, you like the cabins pretty quiet and livable but you wanna make the motor actually sound like it's supposed to, these are gonna be perfect for you. Now they're gonna give you a marginal decibel level increase while not creating any drone and that's thanks to our customers' feedback, and will still be able to have a conversation in the car and enjoy long drives.But from the sounds to the system here, guys, Ford Performance makes quality kits, and these are no exception. This kit's primarily made out of a two and a half inch 409 stainless steel tubing which is considered an optimal metal for exhaust because it's gonna resist corrosion better than aluminized steel. Now it's worth pointing out that if you're on the coast somewhere where you're gonna be seeing snow or rain more often than not, or if you're just in a wet part of the country, 409 may show a bit of surface rust. It's gonna be inherent that any exhaust system's gonna discolor and rust up a little bit with any material. This is something that's likely gonna turn a little bit faster than others. But with that said, guys, it's not gonna be visible as it's gonna be under the car. It's not really something that would keep me up in the middle of the night. But where it counts, you're gonna be getting a very nice three and a half inch polished 304 stainless tips. Those are always gonna look great, they're not gonna rust or corrode. They're always gonna polish up nicely. On the flip side here, guys, if you're overly concerned about that finish under the car and you're after the same decibel level, there are a couple other options out there like MBRP's stainless Pro Series, or LTHs, or a pypes violator that's fully polished, but expect the prices to fluctuate based on the materials. And while we're on topic of pricing, this isn't something that's necessarily gonna burn a hole in your pocket, and being a Ford Performance system, I think it's pretty aggressively priced coming in only at around 380 bucks, and I'd say wouldn't hesitate to bite the bullet here, so to speak. So for the money, if you're looking for a slight bump in volume and tone, it's a great option all things considered. Now if you wanna stay with Ford Performance, you're looking for something slightly louder. Make sure to check out the FR500S back on the website just for comparison. It is gonna be a little bit more throaty. Now and install wise, like I said a little bit earlier, axle-backs are a piece of cake, they install in under an hour with basic hand tools. For that, it's gonna warrant a very easy one outta three wrenches on our difficulty meter. Now looking ahead, guys, this isn't gonna call for the entire tool box, you're looking at just the basics: sockets set, jack and jack stands, and a little bit of WD-40 to hit your existing hangers to get your factory system off. Now, you're gonna you wanna get started getting that car's rear end up off the ground, you're gonna wanna hit those clamps out back with a ton of WD-40 or PB Blaster. Let that soak in a little bit because they're gonna be in there pretty good. So after you let that sit for a couple of minutes, you're gonna start on either side, doesn't really matter which, and you're gonna work on breaking lose the clamps on the over axle pipe. So once that's free, guys, we'll need to do a little bit of a dance and wiggle just to get that out, but it's really nothing crazy here. Once you're done with one side, simply repeat the process on the other side, get your bolts into place, reinstall 'em in the opposite order and you're ready to rock. All right, so that's gonna wrap things up here with me and Ford Performance's Bullit Axle-Back, fitting the '05 through '09 GT and GT500, that can be found right here at

        Ford Performance Bullitt Axle back Exhaust

        Fit and look are good but very quite mufflers. I had installed these mufflers because I had installed the Flowmaster Outlaw Exhaust cat back with off-road pipe and it was too loud( Police didn’t like them ) so I installed these mufflers with the rest of the exhaust I have and it made the car sound like a factory tone “ way too quite” so back to the drawing board.

        Axle-Back Exhaust - Ford Performance

        I have a 2007 Shelby GT. I needed new axle-back exhaust as I had blown the originals. I opted for the Bullitt from Ford Performance as I wanted to keep the original exhaust note that the Shelby had. The Bullitt axle-back did exactly that. No drone at highway speeds, yet when under acceleration a beautiful throaty sound. And my neighbors are not offended by the sound.

        Ford Racing Performance Quality is unmatched

        The Ford Racing Performance "Bullit" muffler is 304 Stainless Steel, so it will last forever. These are not as load as the std steel JBAs that were on my 05 GT for 11 years. These are loud when you are on the throttle, and reasonable when you are not. These will rattle glass at idle, and should not wake the neighbors at 6am. They souond exactly like the demo on AMR's website. I am 53, and and enjoy the V8 noise but not all the time...

        Bullitt axle back

        Great look and fit. Took off 10 year old Flowmasters because I didn't like the drone. However, the Bullitt axle back has a nice tone outside the car, but is a little too quiet for my taste. I may be searching for a happy medium in the future

        Bullitt Axle Back Exhaust

        Unhappy with the product delivered. Box had been opened before (obviously a returned product) greasy finger prints all over it from previous installation, the piping at the connector had been bent, with some surface rust on it. I made a decision to clean them up, and bend the tubing back the best I could, rather than deal with the hassle of returning the product. Quieted the exhaust down and eliminated the “Drone” that my car had. However the tips are not centered in the rear bumper. Had I been notified that it was an “open box” or a previously returned item at a discounted price I would have given five stars.

        Quieter than my last borla made FP

        Sound good, zero drone. Hoping the welds hold up better than the last borla made Ford performance axle backs that I needed to replace.

      Good day, 6 months ago I replaced the the original exhaust of my V6 by the Pypes True Dual Exhaust w/ Black Muffler Tips conversion kit but, for me, it sound and drone too much for daily driving. I would like to know if I can replace the Pipes mufflers by the Ford Performance Bullitt Axle-Back Exhaust without any extra job or modification in the existing piping. Thanks

      • The Ford Performance Bullitt Axle-Back Exhaust will fit the Pypes True Dual Exhaust without extra modification.

      How much is the power gain when these mufflers are installed on a V6 4.0 engine (210 HP) togheter with the true dual exhaust "X" pipes? Thanks

      • The Ford Performance Bullitt Axle-Back Exhaust will typically provide minimal to no gains on most Mustangs. This will be true of all axle-back exhausts, due to the relatively high flow of the OEM mufflers. The X pipe and true dual setup will typically gain around 10-15hp, depending on mods done to the car, as well as if a catted or off road x is used.

      I have a 2008 GT with Pypes Long Tube Headers and Pypes catted H pipe. I currently have SLP mufflers that are way too loud and most importantly have a horrible drone. Will the M 5230 GTB Mufflers have a drone when used with Long Tube Headers?

      • While these mufflers with help cut down on sound and drone it will not completely eliminate the drone that you are experiencing.

      I recently purchased my GT 500 that has the Roush axle back exhaust on it and it's too loud and backs off like it has old glaspacks. What exhaust do you recommend that is close to factory GT 500 sound?

      I have an 05 with the 4.0L as a daily. The previous owner gave it this dual-exhaust kit (, and I don't like it. I do a lot of highway driving and the setup is just too loud and drone-y. I want a more civilized, quieter sound. I have listened to these on a Bullitt car and they sound much better, but will I be able to bolt them on to the current pipes without making crazy bends? I have also looked at the Magnaflow Street Axle-Back Exhaust (, and--if it won't be louder than my current setup--that is also an option (but I don't have unlimited funds). Thank you for your help!

      • The Magnaflow Dual Competition Cat-Back Exhaust will be unable to accept GT axleback exhausts due to its design.
