Review & Install Video

Hey everybody, I'm Justin with AmericanMuscle.com. I'm going to be taking a closer look at the Pypes Pype-Bomb Catback exhaust system available for your 1994 to 2004 Mustang GT and all 1986 GTs and 1986 to 1993 LX 5-liter Fox Bodies. If you guys are on the hunt for quite possibly one of the most aggressive systems available for your 2-valve SN95 or Fox Body, well, then the Pype-Bomb Catback might just be your ticket. Now, this system gets its loud aggressive sound courtesy of these twin M-80 bullet-style mufflers here that are mounted directly behind the midpipe and are straight through design here allowing for maximum performance but also, in this case, maximum sound. In addition to those twin M-80 bullet-style mufflers, guys, this system also consists of 304 grade stainless steel tubing throughout, all of it which has been mandrel bent and is two and a half inches in diameter. I'd say the biggest signature item here with any Pypes system has to be the massive three and a half inch polished tips, which basically act like a megaphone for your 2-valve motor and look pretty good underneath the rear bumper while doing so. Guys, it is worth pointing out that Pypes does offer this same exact system but with black tips instead of the polished options, which you can find here at American Muscle. Since this is a Catback, the install will be slightly more involved but overall not that bad. Figure a couple of hours underneath the car from start to finish getting the factory system removed and the new Pypes system in place. Now, you have to keep in mind we have a ton of useful info back on the product page if you're not already there, including both customer and manufacturer submitted install guides. So be sure to check those out before you start wrenching. So if you're looking for one of the more aggressive Catback exhaust systems available for your SN95 or late model Fox Body, then be sure to check out the Pypes Pype-Bomb Catback exhaust system right here at AmericanMuscle.com.

Increase in Performance and Sound. Upgrade your V8 Mustangs exhaust to a Pypes "Pype-Bomb" Cat-Back Exhaust with Polished Tips and yield an instant increase in horsepower at the rear wheels. It features two of Pypes high flow M-80 Bullet Style Mufflers for the ultimate in unrestricted flow and power gains and a deeper throaty tone.

Aggressive Throaty Sound. The Pypes "Pype Bomb" CatBack exhaust system features two high flow straight-through M-80 Bullet style mufflers that are mounted directly after the Mid Pipe to produce an aggressive deep throaty muscle car tone that is further enhanced with the help of a set of "Pype Bomb" stainless steel resonator tips.

Quality Materials. This Pypes Cat-Back Exhaust is constructed from free flowing mandrel bent 2.5" diameter 16 gauge 409 stainless steel tubing and features two Pypes M-80 Bullet straight-through mufflers for an aggressive throaty sound. The whole system is finished off with a set of 3.5 polished 304 stainless steel resonator tips for modern Muscle Car styling.

Application. The Pypes Pype-Bomb Cat-Back Exhaust kit is specifically designed to simply bolt-on to the existing stock H-Pipe of any 1986 GT, 1987-1993 LX 5.0, 1994-2004 GT, 2001 Bullitt, and 2003-2004 Mach 1 for more power and an aggressive sound.

I have sr coilovers. I am having issues with the catback I have now. It hangs a little to low. I was told it was a bassnai catback but not sure if it's a true catback or just mufflers. The mufflers are turned at a weird angle because if they aren't the pipe hits the control arm. Wanted to know if these would sit higher or if any one has had this issue before. Thanks


V6 Fitment- Will this fit a v6 with a Pypes Off-Road X-Pipe (99-04 V6) ( https://www.americanmuscle.com/pypes-9904-v6-or-xpipe.html ) or will it not be possible? i had this setup on my 96 gt and loved the sound.


Will this fit my 96 v6


  • The Pypes Pype-Bomb Cat-Back Exhaust is not designed o fit your 1996 Mustang equipped with a V6. You can use this exhaust with the correct X pipe designed to be used with a V6 Mustang and a GT catback.

    Much better then I expected.

    Bought for my 91 LX, this catback is mated to a BBK H-pipe, chrome BBK long tubes, which is coupled to a 347. I am extremely please with this cat back. I bought it instead of the other brand that AM sells since it is basically the same thing but this one was actually in stock and $100 cheaper. All I can say is wow! I never expected it to be so good. I had the typical Flowmaster cat back that the previous owner installed. It was old, rattly, and rusty. Since I had the car apart for the LT's and H pipe I decided to do the cat back as well. Fitment is better then i expected, the all SS construction is very nice, the over axle tubes were slightly oval'd which made mating up the mufflers a challenge, nothing major though (installing exhaust is always tough without a lift). As for the sound, the drone I had from the Flowmasters is gone, the idle is super deep, it isn't too raspy, and the overall sound is better then I could have hoped for. Definitely give this CB a strong consideration if you are looking for a replacement for you current system.

It bolted right up with minimal problems and looks perfect...The sound is amazing and its has a nice rumble when driving which is not to loud( passed a cop no more than 2 min after taking it out) but when you get on it, it roars...really throaty/mean sound...nice to drive/hear a mustang w/o the usual chambered muffler sound

    Impressive Quality

    I bought this kit for my Mach 1 and was very impressed with it the moment I took it out of the box. The level of craftsmanship was much more than I was expecting. The welds looked good and the entire kit come polished to a brilliant shine. Installation was a pain in the a**, but that is to be expected when installing an exhaust system of any sort without a lift. The most time consuming part was getting everything to line up properly. I found that what worked best for me, was to first focus on getting the mufflers tucked up as high as possible, then make the final adjustments at the tips. After doing this, the ground clearance is excellent. Both mufflers sit about flush with the factory sub-frame connectors. The only issue/complaint I have with fit and finish is that I was not able to get one of tips to fully cinch down on the pipe, allowing it to move around while driving. I plan to have everything finish welded at some point so it's not too big of a deal, but still worth mentioning. Finally, in terms of driving experience, simply astounding. My car sounds incredible from idle, all the way up to 6,800 rpm. I was also surprised to find that there was no noticeable drone at highway speeds. Next up: long tubes and O/R X-pipe!

    Great Tone

    This catback exhaust kit by Pypes has a great deep tone that sounds great when on the throttle. The sound is just right, not extremely obsessive but has just enough tone to let people know you're coming. After I took my time to set the system it turned out great, with the 3.5 SS tips out the back everyone notices.

    From the moment I bought this exhaust I have loved it! It isn't quiet, which is pretty much what I was hoping for. When my car was N/A it gives it a real muscle sound that I have been looking. Sounds even better now with my turbo. Definitely recommend.

    This exhaust is just unbelievable, I've put it on my 2002 V6 with a X-Pipe and WOW what a difference! The raspy sound give me a huge smile every time I take it up to 3000-3500 rpm. And the look is awesome, dual exhaust is way nicer than the original single one. Thanks American Muscle to provide me this great product in a short time.

    Not as advertised.

    My 2000 mustang GT had flow masters on when I bought it. They sounded very good. Throaty , loud. Deep. But the pipes were starting to rust so I bought this kit from Pypes. they are ok. One of the bolts snapped when I was putting on The tip. so had to run out and buy another. No biggie there. Honestly I thought they would be louder. You almost can not hear it at all at idle. And you really have to rev the engine to get a great sound. or while driving keep the RPM up. If I knew what I know now. I would have just bought another set of flowmasters .. I'm not saying they are bad. Just not as loud or as good as advertised.

    I purchased this exhaust along with the pace setter h-pipe adapter for my 04 v6. and I must say, I am very pleased. The sound difference was instant as soon as I turned the key! Shipping was quick and was installed at a shop. I did also notice a slight power increase. I would highly recommend this to any v6 owner wanting to wake up the sound. People comment and ask me if its a v8 a lot!!! Money well spent.

    Extremely Surprising

    A few months ago I bought Pypes m80 mufflers (not catback) and they sounded great but I am not a big fan of dumps and I didnt feel like fighting tailpipes so I bought these catbacks. Super easy to install even without using instructions and they sound amazing. They give it a nice rasp and roar to my 5.0. They arent too loud at idle but scream when you get on it. Amazing quality. I couldnt be happier!

    I purchased this catback for my 02 v6 not knowing what I was getting into, I had heard some v8's with it but I knew my six banger would not sound the same. I took it to a local shop and had them install an h-pipe from pacesetter along with it. (Keep in mind my mustang's exhaust was stock). Installation was about two and a half hours, and the sound was instant. It seriously sounds like a v8, and I've had 2 people asking me if it was. Idle is fairly quiet but as soon as you step on the the throttle it roars, and is mild when cruising. Definitely recommend for any kind of driver. Other mods: SR CAI

    Sounds Great!!

    The catback system is a well put together kit. All the parts were undamaged and shiny. It took longer than it should have,(about 4 hours) but it was no big deal. The passenger side section that goes over the axle was a bit tricky. I had to disconnect the shock and quad shock to drop the axle on that side a couple inches. And then once I got that figured out, trying to get the kit to line up even and easily was a bit difficult. I am not complaining at all about the system. I enjoyed working on my car, it is calming for me. After dealing with 140 13 and 14 year olds all day, it is a welcome reprieve. Overall it is a good product. The instructions could have been a bit more descriptive or with more pictures. If you want something loud, then this will suit your needs. I am running a factory H-Pipe and it is about as loud as my wife can handle. I was looking for something that would sound different than Flowmasters, and it does.
