Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is engineered for drivers who want a bold, unmistakable exterior soundtrack without turning their daily commute into a drone-filled experience. Built for the 2015-2023 Dodge Charger SRT 392 and R/T Scat Pack models with the 6.4L engine, as well as the SRT Hellcat equipped with the 6.2L engine, this complete bolt-on system pairs Flowmaster’s signature performance engineering with a refined, purpose-built design that transforms both the sound and the flow of your Charger.
At the heart of the system is Flowmaster’s exclusive dual 3.00-inch Scavenger Series X-pipe assembly, designed to maximize power and deliver a deep, unique tone. Mandrel-bent tubing keeps exhaust gases moving efficiently, feeding into a pair of specially built Super 40 Series mufflers with 3.50-inch internals that produce a deep, powerful sound. The result is an aggressive exterior note balanced by a moderate interior volume, so you get the presence you want with the comfort you can live with.
Key Benefits
Constructed from durable 409S stainless steel, this cat-back system is built to handle the heat and endure the miles. The tailpipes are finished with a pair of large 4.00-inch polished stainless steel tips embossed with the Flowmaster logo, adding a clean, aggressive look to the rear of your Charger. Because it mounts using the factory hangers and includes all necessary parts and hardware, installation is a straightforward, bolt-on job you can complete at home.
