Grail Dodge Challenger / Charger Exhaust

Command the streets with deep, aggressive sound – unleashed at your command.

Unlock the full potential of your Dodge Challenger or Charger with our premium stainless steel cat-back exhaust system, engineered for the 6.1L, 6.2L, and 6.4L HEMI engines. Built from high-grade 1.4301 (V2A) stainless steel with an impressive wall thickness of up to 2mm, this system offers unmatched durability and a rich, powerful tone without any unwanted rattling or droning.

Designed exclusively for models equipped with a factory exhaust valve system, our setup retains your original tailpipes for a clean, OEM+ appearance. Featuring a precisely tuned H-pipe layout, the system enhances the deep V8 rumble while optimizing exhaust flow.

Thanks to intelligent valve control, you can choose between two distinct sound modes:

• Quiet Mode: Exhaust valves remain closed for a refined and subtle presence, opening only above 4500 RPM to unleash performance when needed.
• Open Mode: Exhaust valves remain fully open, delivering an aggressive, full-bodied roar at all times.

Mode selection is effortless using the factory RES (Race Exhaust System) button on your steering wheel.

Installation is straightforward and fully reversible, with all necessary hardware and a detailed installation manual included.
