      Review & Installation Video

      Hey everybody, I'm Justin with 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

        Where's the beef?

        I got one box with two pipes in it. No polished tips, no mufflers, no clamps. I'm hoping that there is at least one more box still adrift in the shipping system because I most surely didn't get what was promised.

        Great sounding and Nice looking

        Product fit really well. It was a real struggle to get everything lined up properly. Only complaint, had to modify tip hanger to make fit on my year due to non cut-out bumper.

        pypes for 1998 mustang gt

        I only replaced the cat-back and not the midpipe or headers. So i wasn't expecting huge volume changes, but definitely something with some growl. I wasn't disappointed. I can't wait till I get an xpipe. maybe the bbk? I don't know. thanks AM.

        2 1996 GT - DevinS Installation Time: Full Day

        Missing tip.

        So received at a normal time. Discovered that one of the tips was missing. As this is a mounting point for the system it could not be used as shipped. Contacted AM and Pypes. And they were out of stock. About a month later. I SHOULD have one coming my way soon. A shipping fault I'm sure. Frustrating nonetheless. Also did not have instructions which was also likely due to shipping.

        1 1995 GT - AlanJT Installation Time: Weekend

        Had better luck with lower priced exhaust

        The fit was terrible. I had to cut and re-weld the hangers. I've bought lower priced cat backs that fit better. And on top of that, too loud. On the video they sounded great, but that car has a 4.6 and mine is a 5.0, so I guessing that is a factor. After a month I took off the mufflers and put on a set of Flowmasters. Much better.

        Love the sound

        I paired this with their off-road x pipe on my 95 gt and OMG it was amazing. The exhaust note is superb. You definitely cannot sneak around in the car anymore, but I did not want to be able to, I want it to turn heads and it definitely does.

        94/95 not happy

        pipes sit to low even after i soldered every thing together. clipped the under toe with in the first day on a bump in the road and after crippled a mount point. now a constant rattle in the tire well. I wish i had sicked to magnaflow they were a proper bolt on fit for my 95. I went from a roaring tiger to a angry puma the sound is nice but the whistle is their . The performance is spot on and if it was not for the proper fitting i would have enjoyed the pipes. Needless to say with the low hang and welding i did not helping i will scrap the Pypes after 3 weeks and get a magnaflow cat back more fitting for my car . I wish i had tried not to save the $200 dollars on this part and went with my gut,

        5 1998 GT - 98GT Installation Time: Shop Install Installation Cost: 0-$100


        Sounds great. Nice sound at startup and isn't too loud if you drive with a light foot. Comes to life when you step on it though. I did have this installed at a shop and they had to do a little cutting and welding and make some adjustments to fit right. At the same time I had them custom make an x-pipe to pair up for it. Cost for the x-pipe and all the installation for all of it was $190. Told me it would be $80 to just install the pype bomb.
