Description

The SLP LoudMouth Cat-Back Exhaust System (part number SLPD31040) is engineered to enhance the exhaust note and performance of select 2011-2014 Dodge and Chrysler models equipped with the 5.7L HEMI engine. This system is specifically designed as a direct-fit cat-back replacement, meaning it replaces the factory exhaust components from the catalytic converter back. Constructed from durable stainless steel for longevity and corrosion resistance, the LoudMouth system features a 2-1/2 inch diameter main tubing and 3 inch polished tips. This setup is intended to provide an aggressive, race-inspired exhaust tone.
