    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.

            Loud but cool sounding

            I must say, these were pretty easy to install. Took about 4 hours. So far no rubbing against the body, just have a few leaking connections. Wanted to drive it before tightening the connections down.

            Terrible fitment

            Had a customer bring this system to my shop to be installed on his 91 LX. Fitment is absolutely terrible. I build custom one off exhausts and I couldn't believe how bad it was down to wrong hangers included with the kit. The passenger side tail pipe was bent wrong and wouldn't allow me to line the tips up correctly. On the upside it does sound very good.

            Great Exhaust, Wrong Part

            The exhaust sounds amazing, it's a very unique note and has the rumble I've been looking for instead of just the dull hum the car came with. (97 GT) It's somewhere between aggressive and calm so it is amazing for a daily driver. However I was sent the correct mufflers but one must have been for a different car because it was was not angled right. My shop ended up cutting a custom tailpipe and its correctly installed now but it was kind of inconvenient on both ends that it had to be done. Definitely worth the money. Just make sure you have the correct parts.

            Great Sound

            Install was PIA, but nothing to do with the product. The manifold studs broke and needed drilling and tapping. The fit and finish is very good for the money. Previous owner of my car removed the cats. I added Pypes catted x-pipe and the Pype-Bomb cat back. Overall nice sound. It's subtle. Not as loud at idle, but very nice when rolling through the gears!

            Didn’t fit my 99 gt correctly

            Took it to a shop to get it installed and this particular shop specializes in exhaust changes, and they didn’t fit at all, he had to do a lot of cutting and welding to get the right fit for my GT mustang. They do sound amazing but just the cost to get it in was outrageous when on average exhaust isn’t very expensive to do at a shop

            Pretty good sound

            Great sounding exhaust. Don’t fit quite right and the tip hangers needed to be bent into the correct shape. Took much longer to instal than any bolt on cat back should.

            These pipes are one of the best in my opinion, they are loud and have that muscle car tone, i installed them in my mustang, i recommend pairing them up with a pypes x-pipe as well

            systems costing 2 or 3 times as much may give you a better exhaust note but thats a matter of opinion.this system sounds good.low rumble at idle,good roar at full throttle.came with everything needed.friend at muffler shop installed for case of bud.3 and 1/2 in tips look awesome sticking out back.overall very happy.

            Awesome sound

            I bought this catback along with the pypes off road xpipe for my 2002 GT and let me tell you .It sounds incredible.It looks really nice too and I love the tips that come with this. At idle its surprisingly quiet, considering that the mufflers are just straight thru.but when you get on it ? its a beast. I love how it crackles on downshifts . Ive owned chamber mufflers before like mac and flowmaster.i didn't think these would sound as good but I was wrong .They sound way better . And they sound like they've broken-in after about 2 months and sound even louder. Theyre not obnoxious if you drive normal but if you let the rpms climb alittle like 3k rpm's and it will put a smile on your face.

            I've had this system on my car for about 2 months now and I love it with the O/R Xpipe it is deep and is loud when you want it but when you put it in 5th and are cruising at 70 its not that loud or droney.

            Very nice budget conscious pipes

            I had a local mechanic put them in (and a fuel filter) and he said it took about 2 hours which is about what other reviewers have said. I like the sound coming out the exhaust and through the floorboards. It "woke" the car up. Coupled with a 91 octane canned tune I feel an increase in power using the butt dyno. I'd buy these pipes again and recommend them to a friend.

            Actually, thought it would be louder. Good mileage, but let down. I may have made a different decision when it comes to exhaust options...I expected louder. Used a lift, easy install, but very quiet. Not what I expectef for a highly recommended exhaust.
