      Powerful Tone. Your Mustang has a beast under the hood; unleash its roar with the SLP LoudMouth Axle-Back Exhaust. It boasts larger-than-stock, 2.5-inch stainless steel piping, and minimal curves and bends for incredibly unrestricted flow, plus there's no sound-deadening packing, so you get a beautiful, pure racing sound.

      Increased Power. The LoudMouth Axle-Back Exhaust from SLP takes the chains off your Stang with wider tubing and fewer bends. With fewer restrictions, your Pony gets increased exhaust flow and reduced backpressure, which lends you a boost in both horsepower and torque.

      Stainless Steel Build. SLP manufactured the LoudMouth Axle-Back Exhaust system with 2.5-inch diameter mandrel-bent stainless steel tubing and a pair of custom tailored 304 Stainless Steel tips. That gives it a balance of durability and light weight. In fact, it'll shave 29 pounds off your stock system.

      Cut & Clamp Installation. Installing the LoudMouth Axle-Back Exhaust system is quick but will require some cutting and clamping. Everything you need for a smooth installation is included in the box.

      Application. SLP designed the LoudMouth Axle-Back Exhaust system to fit 2015-2017 V6 Mustangs.

        Did not fit my cars pipes at all! The stock 2017 mustang pipes are 2 1/4” And these are 2 3/4” so they did not fit at all.
