      Aggressive Race Car Tone. With Flowmaster’s FlowFX’s Cat-Back Exhaust with Black Tips, your HEMI Dodge Challenger will definitely turn heads as it goes down the track. Thanks to its Scavenger X-Pipe cross-over and quality mufflers, the system is tuned for maximum performance and tone, giving your vehicle an aggressive race-ready sound.

      Improved Torque and Horsepower Gains. The FlowFX mufflers that are featured in this kit boast a straight-through design. This means the mufflers are capable of generating a more efficient exhaust flow. As a result, your Challenger will gain an increase in horsepower, torque and improve its overall performance.

      Quality Construction. Made in the USA the FlowFX Cat-Back Exhaust features a high-quality 3-inch mandrel-bent, stainless steel tubing construction. Its 3.50-inch tips, on the other hand, are made from 304s stainless steel and come with a black ceramic coating. As a result, the entire system boasts remarkable strength and long service life.

      Moderate Installation Level. Installing this system is challenging, so having at least a moderate mechanical skill level will make the task easier to complete. The entire process will also only take 2 hours since all of the product’s necessary hardware and instructions are included in the kit.

      Application. This Flowmaster FlowFX Cat-Back Exhaust with Black Tips is designed to fit 2017-2021 Dodge Challenger models equipped with the 5.7L HEMI engine.
