      Throaty Muscle Car Roar. Give your Mustang the aggressive sound it should have had from the factory by installing a CGS Motorsports Cat-Back Exhaust. A CGS Cat-Back with its X-Pipe and performance mufflers will add a muscle car roar to your Coyote powered GT, without any of the annoying interior drone associated with most aftermarket exhaust systems. This CGS Motorsports Cat-Back is great for the driver who wants to hear the throaty sound of their exhaust as well as their high end sound system while cruising around town.

      More Horse Power. Not only will a CGS Motorsports Cat-Back improve the sound of your GT Mustang, but it will also improve its horse power as well. CGS designed their Cat-Back Exhaust System with an X-Pipe and a pair of high flow, chambered performance mufflers. The mufflers feature a very unique chambered design that was specifically developed to increase exhaust flow for an impressive boost in power. By replacing the restrictive factory mid pipe resonator and mufflers with a CGS Motorsports Cat-Back you can expect to see an increase of 30.8 horsepower at the rear wheels.

      High Quality Construction. CGS Motorsports Cat-Back Exhaust systems are manufactured right here in the USA with pride. CGS uses mandrel-bent 3" diameter T304 stainless steel tubing for excellent exhaust flow and enduring corrosion resistance. The included performance mufflers are constructed from high quality, T304 stainless steel that is fully welded for superior strength, with no epoxy adhesives that can fail. This Cat-Back features two massive, 4.0" diameter, slant cut, 304 stainless steel tips for impressive muscle car styling.

      50 State Street Legal. This CGS Motorsports Performance Muffler Cat-Back Exhaust System is 50 state street legal and will not affect factory warranty or emissions standards. CGS Motorsports backs their exhaust systems with a Lifetime Warranty.

      Direct Bolt-on Installation. The CGS Motorsports Cat-Back with X-Pipe was engineered to bolt straight up in the stock location, after the catalytic converters, with no cutting required for installation. This 3" Cat-Back includes 2.5" step down flanges so that it can be installed with the factory or any aftermarket 2.5" exhaust system. Please note, convertible models with the additional brace underneath the vehicle, will be required to use a 1 inch spacer with the brace or would need to remove the brace completely.

      This CGS Motorsports Performance Muffler 3" Cat-Back Exhaust System is specifically designed to fit the 2015 to 2017 GT Mustangs equipped with the Coyote 5.0L DOHC V8 engine.

        Easy install, nice sound

        This system installed easy, all parts fit and where of good quality. Nice throaty sound. Increase highway noise a little, bit not a lot. Solid value at the sale price.

        So I bought this system with the black Friday sale and received it today. Installed the complete system by myself in about 3 hours, and other than wishing I had another helper for the stock system removal, it was fairly simple. I love the exhaust so far and so do my kids. I would have honestly given it a 4.5 star review because of the HORRIBLE clamps that it comes with, but I thought that would be unfair. Thanks American Muscle!
