SLP LoudMouth sports exhaust system for Dodge Charger 5.7

These SLP sports exhaust systems ensure a noticeable increase in performance and are designed with LoudMouth's innovative modular technology. This allows you the flexibility to change the performance and noise characteristics by switching from the spherical resonators to the quieter silencers to suit your ever-changing individual requirements.

Each system consists of 2.5-inch mandrel-bent stainless steel tubing for unobstructed flow with an integrated “PowerFlo-X” cross pipe that bolts to the factory downpipes. Complete hardware and installation instructions are included for easy and quick assembly.

The SLP LoudMouth D31040 fits the following models:

Important note for vehicles with cylinder deactivation:

Due to cylinder deactivation, the sound in 4-cylinder mode in conjunction with a sports exhaust (regardless of the manufacturer) is often perceived as “unsuitable”.
We can fix this by electronically disabling the cylinder deactivation.
The vehicle then always runs on all 8 cylinders and permanently has the desired V8 sound.
