Product Description

The CORSA 21389 delivers a complete cat-back overhaul for the 2025-2026 Ram 1500 RHO's twin-turbo 3.0L Hurricane inline-6, replacing everything rearward of the catalytic converters with a 3.0" 304 stainless steel true dual-path system. Two separate mufflers, each with an integrated X-pipe, keep flow balanced across both sides while shaping a genuinely custom-tuned tone for this specific engine platform.

CORSA describes the result as a "true Jekyll and Hyde experience" - noticeably more aggressive than the stock system on cold start and under acceleration, yet completely silent at highway cruise thanks to patented No Drone RSC technology eliminating the resonant frequencies responsible for cabin drone. This satin-finish version pairs with 5.0" dual-wall, flat-cut Satin Pro-Series tips; the same system is also available with black or gun metal tip finishes for owners who want a different look with identical performance and sound.
