2015-2023 Dodge Challenger 5.7L QTP Screamer Cat Back

If you're looking to give your 2015-2023 Dodge Challenger with the 5.7L HEMI engine a more aggressive sound and improved exhaust flow, this QTP Screamer cat-back system is designed to do just that. This system replaces your factory exhaust from the catalytic converters back, aiming to unlock more of that V8 rumble and potentially offer a slight bump in performance.

Crafted from durable 304 stainless steel, this cat-back system is built to withstand the elements and resist corrosion, ensuring it holds up over time. The Screamer series is known for its aggressive tone, so expect a noticeable increase in volume and a deeper, more resonant sound compared to stock. The system is designed as a direct bolt-on replacement, meaning it should install without requiring any welding or cutting, making the process more straightforward. The 3-inch diameter tubing is optimized for the 5.7L HEMI to help reduce backpressure and allow the engine to breathe more freely.

When installing this system, it's always a good idea to have a helper, as exhaust components can be awkward to maneuver. Ensure all hangers are properly aligned and that the system has adequate clearance around the driveshaft and body to prevent any rattling or interference. While this system is designed for improved sound and flow, it's important to check local noise ordinances as the Screamer series is quite loud.
