CORSA Sport 3" Cat-Back Exhaust with 5" Satin Tips for 2025-2026 Ram 1500 RHO

Give your 2025–2026 Ram 1500 RHO a more aggressive performance sound with the CORSA Performance Sport 3.0-Inch Cat-Back Exhaust System with Satin Polished 5-Inch Tips. Engineered specifically for the RHO and its 3.0L High Output Hurricane twin-turbo inline-six, CORSA Part #21389 replaces the factory cat-back exhaust with a freer-flowing dual-rear-exit system designed to increase exhaust flow, reduce weight, and dramatically enhance the sound of the Hurricane powertrain.

CORSA designed this system specifically around the unique exhaust characteristics of the RHO rather than adapting its standard Ram 1500 Hurricane exhaust. The manufacturer lists Part #21389 specifically for the 2025+ Ram 1500 RHO Crew Cab Short Bed with the 5'7" box and 144.5-inch wheelbase. This is important because CORSA's standard 3.0L Hurricane Ram 1500 system specifically excludes both the RHO and High Output Hurricane applications.

The RHO system uses a 3-inch cat-back configuration terminating in a dual rear exit. CORSA reports that its RHO exhaust provides a 37% increase in exhaust flow compared with stock while also removing approximately 10 pounds from the vehicle. The improved flow gives the twin-turbo Hurricane a less restrictive exhaust path while reducing unnecessary exhaust-system mass.

Sound is where this system really separates itself from the stock exhaust. CORSA rates Part #21389 at its Sport sound level and reports an increase of approximately 15 decibels over stock. The result is a much more pronounced exhaust presence that allows the High Output Hurricane engine to be heard under acceleration without turning the RHO into an excessively compromised street truck.

At the rear, this configuration uses dual 5-inch single tips with a Satin Polished finish. The tips feature dual-wall construction and a straight/flat-cut profile, giving the RHO a substantially more aggressive appearance while filling the factory rear bumper exhaust openings.

For RHO owners looking for a complete cat-back system rather than a simple muffler or mid-section replacement, the CORSA Sport system combines vehicle-specific engineering, increased flow, reduced weight, a significantly more aggressive exhaust note, and oversized premium tips in one complete package.

CORSA Sport Sound

This RHO system is tuned to CORSA's Sport sound level, providing a substantial increase in exhaust presence compared with the factory system.

CORSA's published testing rates this configuration at approximately:

+15 decibels over stock.

That makes this an excellent option for RHO owners who want the Hurricane engine to sound considerably more aggressive when accelerating while retaining a vehicle-specific exhaust system engineered specifically around the truck.

37% Increase in Exhaust Flow

CORSA reports a 37% increase in exhaust flow compared with the factory RHO exhaust system.

Reducing exhaust restriction is particularly relevant on the RHO's twin-turbocharged Hurricane engine, where exhaust gases must exit efficiently after passing through the turbochargers.

Rather than making unsupported horsepower claims, I would market this system around CORSA's manufacturer-tested 37% flow improvement, which is a much stronger and verifiable performance specification.

Approximately 10 Pounds Lighter Than Stock

In addition to improving flow, CORSA reports that the system removes approximately 10 pounds compared with the factory exhaust.

That gives customers three manufacturer-documented improvements over the stock RHO exhaust:

+37% exhaust flow

+15 dB sound increase

-10 lb weight change

These are excellent specifications to highlight visually on the Rogue Offroad product page.

3-Inch Cat-Back Design

The CORSA RHO exhaust is a complete 3-inch cat-back system with a dual rear exit configuration.

Manufacturer specifications list:

• Pipe Diameter: 3.0"
• System Type: Cat-Back
• Exit: Dual Rear
• Sound Level: Sport
• Tip Size: 5.0"
• Tip Style: Single
• Tip Construction: Dual Wall
• Tip Cut: Straight / Flat Cut

5-Inch Satin Polished Tips

This specific configuration finishes the RHO exhaust with large 5-inch Satin Polished tips.

The tips feature:

• 5" outlet diameter
• Dual-wall construction
• Straight/flat-cut profile
• Satin Polished finish
• One tip at each rear exit

The oversized outlets provide a much more substantial appearance within the RHO's rear bumper openings and complement the truck's wide, aggressive factory styling.

RHO-Specific Engineering

This is an important distinction for the Rogue Offroad listing.

CORSA manufactures another 3-inch Sport cat-back for the regular 2025+ Ram 1500 3.0L Hurricane. However, that system specifically states:

• Does not fit Ram RHO
• Does not fit trucks equipped with the 3.0L High Output engine

The RHO therefore requires its own application-specific exhaust system.

CORSA Part #21389 is the RHO-specific system.

That distinction should remain very clear in Rogue's catalog to prevent customers from purchasing the standard Hurricane exhaust for an RHO.
