SLP LoudMouth Sports Exhaust System for Dodge Challenger SRT 6.1 & 6.4

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

The LoudMouth Cat-Back exhaust system for the 2008-2014 Challenger 6.1L/6.4L HEMI SRT8 is now available in LoudMouth and LoudMouth II designs. The modular stainless steel cat-back system is so technologically advanced that you can easily improve the performance and noise level of your Challenger by replacing the included bullet resonators with milder SLP mufflers (part no. 31067) can change.

The SLP Sport Exhaust System consists of 3-inch stainless steel pipes with mandrel bends for unrestricted flow with an integrated 3.0-inch PowerFlo-X crossover pipe that bolts to the factory 2.75-inch downpipes.

The original Challenger square exhaust tailpipes fit this exhaust system. All parts and installation instructions are included.

NOTE: Designed for use with original exhaust manifolds.

Important note for vehicles with cylinder deactivation:

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

For customers who purchase this SLP exhaust system from us, we offer the deactivation of the cylinder deactivation on this model at a preferential price of 179,- Euro (instead of 279,- Euro) incl. VAT.
