      Unique Race-Ready Sound. If you’re looking for a moderate exhaust tone that still sounds aggressive and race-ready, consider getting the Flowmaster FlowFX Center/Center Muffler. This muffler has a unique sound that’s different from the “chambered” sound for which most Flowmaster mufflers are known.

      Enhances Exhaust Flow Efficiency for Better Overall Performance. The Flowmaster FlowFX Center/Center Muffler doesn’t only improve your Mustang’s sound, but it also enhances its exhaust flow. By modifying the exhaust system, you decrease the choke points that can cause build-up, which in turn robs power from your engine. This is a great investment because it will give your car more power and torque, and better fuel mileage.

      Strong and Durable Stainless Steel Construction. The Flowmaster FlowFX Center/Center Muffler is made from high-strength, 409S stainless steel. This material is very strong and durable, and won’t get warped out of shape just from normal usage. The muffler also has a round body with a length of 14 inches, and 3-inch inlet and outlet,while finished in a classic, brushed stainless steel look. As a result, this product will deliver excellent performance for many years to come.

      Straightforward Clamp-On Installation. Installing the Flowmaster FlowFX Center/Center Muffler is straightforward and easy. After all, it is a direct stock replacement, so you only need to properly clamp the inlet and outlet on. It’ll only take you around 2 hours and a bit of elbow grease to install this on your car.

      Covered by a Limited 1-Year Warranty. Flowmaster warranties the FlowFX Center/Center Muffler against defects in materials and workmanship for a period of 1 year starting from the date of purchase. This warranty shall only honor claims by the original purchaser and the vehicle on which it is originally installed.

      Application. The Flowmaster FlowFX Center/Center Muffler fits all Ford Mustang models.

      2 Top Rated Questions

      How does the sound from these compare with sat the SLPs?

      • If your talking SLP Loudmouths, honestly really only a sound clip will answer that question. In regards to volume, these and the Loudmouths are on the list of the absolute loudest mufflers we have to offer.

      Anyone use these as resonators on their mustang GT?

      • This would not work as a resonator as these are straight through mufflers. It's just an opened pipe, designed in such a way to make the exhaust note even louder than a regular straight pipe.
