Product Description

The CORSA 21389GNM delivers the same complete cat-back overhaul as CORSA's other RHO exhaust options, built for the 2025-2026 Ram 1500 RHO's twin-turbo 3.0L Hurricane inline-6, finished with 5.0" Gun Metal Pro-Series tips for a distinctive, upscale look that sits between the satin and black finish options. A 3.0" 304 stainless steel true dual-path system routes through two separate mufflers, each with an integrated X-pipe, keeping flow balanced across both sides while delivering a genuinely custom-tuned tone for this engine.

CORSA describes the result as a "true Jekyll and Hyde experience" - noticeably more aggressive than stock on cold start and under acceleration, yet completely silent at highway cruise thanks to patented No Drone RSC technology. Whether the satin, black, or gun metal tip finish suits the truck's exterior best, all three share identical performance and sound characteristics - this is purely a styling choice.
