      Increase in Performance and Sound. Bolting on a Pypes Mid Muffler Cat-Back with Black Tips on a stock 2005-2010 GT will give your Pony an instant 5 to 10 horsepower gain. It features (2) of Pypes M-80 Bullet Mufflers for the ultimate in flow and power, accompanied with a deeper throaty tone.

      Aggressive Throaty Sound. The Pypes Mid Muffler Cat-Back features two high flow, straight-through M-80 Bullet Mufflers that are mounted directly after the Mid Pipe to produce that aggressive, deep, throaty muscle car tone of yesteryear.

      Quality Materials. This Pypes Cat-Back Exhaust System is constructed from free flowing mandrel bent 2.5" 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 4" Black Powdercoat 304 Stainless Steel Tips for modern muscle car styling.

      Application. The Pypes Mid Muffler Cat-Back Exhaust with Black Tips is specifically designed to simply bolt-on to the existing factory H-Pipe of the 2005-2010 4.6L GT or Bullitt Mustang for more power and a louder more aggressive sound.

      Technical Note. Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

        4 2005 GT - Waldo Installation Time: Less than 1 Hour

        Awesome !

        Fitment is perfect ! Took it to my local muffler shop and they installed it in 30 minutes. It sounds amazing and definitely some horsepower added to my mustang. Some drawbacks are not as loud, I had straight pipes so definitely quieter now. More than likely they’ll have to cut the metal pins so it sits perfect, which I believe voids warranty. And make sure they sit straight, if not aligned properly during installation they will move inward and hit your bumper.

        Pypes Mid Muffler

        Great sounding exhaust. Quite when driving normal. During hard acceleration it is loud and gives an old muscle car sound. Fit was good but takes forever to get all of the pipes lined up. I also recommend welding the rear of the muffler to the over axle pipe. Could not get it to seal just using clamps.

        5 2006 GT - KrystopherB Installation Time: Afternoon

        Awesome doesn't begin to describe these

        Let me start by saying that these Pypes Cat backs are the first non-aesthetic upgrade I've done to my mustang. The total time to remove the old exhaust and install these was less than 2 hours. Be advised, though, we had a lift and air tools. You'll most likely spend the majority of your time twisting the exhaust pipes so the end toward the tips sits flush--this was the most tedious task for us. All in all, great buy. AM delivered the product super fast, as always. Oh and the sound... Loud, but not annoying. It definitely rumbles the way a true muscle car should. I'm in love with the sound, the wife is too.

        Great system

        This catback system sounds amazing. I'm running it with a Pypes O/R X-pipe. I swapped to these from Flowmasters and I love the difference. It has a very good deep tone to it, and it sounds just like a Mustang should. The fitment was rough. Took about 2 hours at a shop to get mine just right. Installation should only be about an hour to two hours at a shop. It also looks good too, the black tips add on well to the black on blue look for my Stang. I'd recommend with a mid-pipe like how I have it, but they have to sound good alone too.

      How is this set different from the Pypes mid-muffler set up for the v6? Both are mid muffler with what looks like the same tips and piping, but i'm guessing there is more that's different as the v6 with duals are usually drone-ridden with almost everything except mid muffler.

      • The Pypes Mid-Muffler True Dual Exhaust - Black (05-10 V6), item # 383696, ( comes with an After-Cat X-Pipe. It is intended to connect to the factory catalytic convertors to convert the single exhaust to a true dual exhaust. The Pypes Mid-Muffler Cat-Back Exhaust with Black Tips (05-10 GT) is designed to bolt up to the factory H-Pipe. They both have a 2.5" tubing with 4" tips, but are designed for different models.

      If I have an existing exhaust system, will this work. I have kooks Lon tubes and non catted H-pipe, will this system still work with that set up .

      • It should work
