2008-2022 Challenger SRT-8 6.1/6.4L SLP Loudmouth Exhaust

Bolt-on some serious power with an SLP Cat-Back Exhaust System

Now available from SLP is the stainless steel, Catalyst-Back Modular Exhaust System for the 6.1L Hemi powered 2008 SRT-8 Challenger. It is available in Loud Mouth™ and Loud Mouth II™ designs. Thanks to the modular design, either resonators or mufflers can be ordered individually and interchanged separately.

These systems provide a noticeable performance gain of up to 12 horsepower and are designed using SLP's innovative modular technology. This enables customers the flexibility to change the performance and noise-level characteristics by switching from our bullet-style Loud Mouth™ resonators, to our quieter Loud Mouth II™ mufflers, in order to suit their individual requirements.

Each system is constructed from 3" stainless steel mandrel-bent tubing, for unrestricted flow with an integrated 3.0" PowerFlo-X™ crossover pipe that will bolt to the factory 2.75" downpipes. Re-Use your factory Challenger Square Exhaust Tips. Easy bolt-on installation and all hardware and installation instructions are included, backed by SLP's Lifetime Warranty.

NOTE: Designed to work with STOCK exhaust manifolds. If upgrading to our Long Tube Headers use part# D30008 (Headers)

NOTE: This part is not compatible with the Challenger SRT8 equipped with a 6-speed manual transmission.
