    Rich Exhaust Note. Step up the sound of your 2015-2017 GT Mustang with Pypes Phantom Series Cat-Back exhaust. This Cat-Back exhaust will add a throaty, muscle car note to your coyote powered exhaust. While using a pair of M80 bullet mufflers and an X-Box Mid Pipe, this exhaust eliminates interior drone but still gives you a rich, muscle car sound to grab the attention of onlookers of wherever it is you're going. The phantom series adds black tips instead of the regular polished, to give a darker, more blacked out look to your ride. This Cat-Back Exhaust has been designed for Mustang owners that have installed or plan to install aftermarket headers to create a full 3" exhaust system on their 15-17 GT.

    Better Flow for More Power. Pypes engineered their Cat-Back System to significantly improve the exhaust flow of your 2015-2017 5.0-liter Mustang. This Cat-Back replaces the restrictive factory 2.5" piping with larger diameter 3" mandrel bent piping, a pair of straight-through bullet mufflers and Pypes unique X-Box mid pipe. With these components in place you will see a noticeable increase in rear wheel horse power and torque.

    M80 Bullet Mufflers. Pypes M80 Bullet Mufflers feature a high-flow straight-through design creating a path of least resistance. Engineered with a layer of stainless mesh around a unique internally louvered core and a lining of basalt insulation, these M80 Mufflers will improve exhaust flow for more power and sound.

    X-Box Mid-Pipe. Designed to eliminate the restrictive factory resonator the X-Box Mid Pipe improves exhaust flow when compared to traditional H and X mid pipes. The combination of the X-Box and the mid-muffler design helps accelerate the exiting exhaust to create significant rear wheel power gains.

    Quality Construction. Pypes Cat-Back Exhausts are manufactured from high quality 304 stainless steel piping for strength and excellent corrosion resistance. All Pypes Exhaust Systems feature smooth mandrel bent tubing to eliminate any power robbing kinks. The Phantom Series is then completed with a set of black 304 stainless steel 4" tips, which also adds bold muscle car styling to your Mustang by creating a "blacked out" look.

    Direct Fit Upgrade. Pypes Mustang Cat-Back with X-Box Mid Pipe bolts straight up with no modifications required for installation. Making this Cat-Back a direct fit bolt-on replacement upgrade.

    Application. This Pypes 3" Cat-Back Exhaust with X-Box Mid-Pipe and Black Tips is specifically designed to fit the 2015-2017 GT Fastback Mustangs equipped with aftermarket headers using a 3" connection Mid Pipe. Not compatible with convertible models.

      Got a nice tone

      It's an excellent deal, not the loudest one, but it's so much better than stock exhaust
