Rich Muscle Car Sound. Let everyone know you have arrived on the scene by installing a Pypes Cat-Back Exhaust. This Cat-Back will add a deep muscle car note to the sound of your coyote powered Mustang's exhaust. Using a pair of M80 bullet mufflers and a X-Box mid pipe this Pypes Cat-Back creates its rich powerful sound without any unpleasant interior drone, so you can converse freely with passengers while tooling around town. Pypes designed their 3" Cat-Back Exhaust for those Mustang owners that are installing a set of aftermarket headers on their GT in order to create a full 3" exhaust system.
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. 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.
