Rich Muscle Car Sound. Give your 2015-2017 coyote Powered GT Mustang a deep rich muscle car sound with absolutely no resonance or drone by installing a Pypes Cat-Back Exhaust. This powerful sound is achieved with the help of a pair of M80 bullet mufflers and Pypes H-Box Mid Pipe that replaces the factory resonator.

Better Flow for More Power. Pypes designed their Cat-Back to significantly improve the exhaust flow of your 2015-2017 5.0L Mustang. By replacing the factory 2.5" piping with larger diameter 3” mandrel bent piping, a pair of straight-through bullet mufflers and Pypes unique H-Box Mid Pipe you will see a noticeable increase in rear wheel horsepower 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.

H-Box Mid-Pipe. Designed to eliminate the restrictive factory resonator the H-Box Mid-Pipe improves exhaust flow when compared to traditional H and X Mid Pipes. The combination of the H-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. Complete with a set of black powder coated 304 stainless steel 4" tips, this Cat-Back also adds aggressive muscle car styling to your Mustang.

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

    First off this is not a stupid loud exhaust it’s a, sounds really good exhaust. I love it. It doesn't give you that much weight loss only about 5 Lbs but there is ZERO! Drone! It sounds amazing and I get told everywhere I go that they like it. I literally had an Amish kid give me the thumbs up. Who can say they have had that happen?! The black tips really pulls the entire car together. It just makes this car sound like it should have. Now for the fitment was horrible, the hangers either where never bent right or they got messed up in shipping so that was…fun. I couldn't get the driver side tube to connect perfectly it was like the pipe was just a bit too short. Didn’t effect sound though.
