TRX vs RHO

JB4 Tuner for 2025+ RAM 1500 & RHO 3.0L I6 Hurricane Twin Turbo

A piggyback tuner that sits between the Hurricane engine's sensors and the factory ECU rather than replacing the factory tune outright, rated for up to 104 wheel-hp on pump gas and removable without a trace for dealer visits. It's not VIN-locked and updates over Bluetooth, but manipulating fuel and spark signals on a turbocharged engine is exactly the kind of mod that draws scrutiny if a powertrain warranty claim comes up.

Corsa Performance 2025+ RAM 1500 RHO Cat-back Exhaust (Sport, DRE, 5.0 in Single Tips)

A 3-inch true-dual cat-back built for the RHO's turbo six, sold only in Corsa's 'Sport' sound level for this application. It's a direct bolt-on with no cutting required, but Corsa explicitly excludes trucks running the factory GT Package exhaust, so check which system the truck has before ordering.

CORSA 2021-2024 RAM 1500 TRX 6.2L Exhaust (Xtreme Cat-Back, 21189)

A 3-inch 304-stainless true-dual cat-back with Corsa's Reflective Sound Cancellation, built specifically for the TRX's 145.1-inch-wheelbase crew cab and backed by a limited lifetime warranty. It's cat-back only, the factory catalytic converters and mid-pipe stay in place, so emissions legality isn't in question.

Cold Air Intake For 2025-2026 RAM 1500 RHO

A dedicated intake for the RHO's 3.0L Hurricane twin-turbo six with a filter outlet sized over 6 inches versus the factory 4.25-inch design, aimed at improving turbo airflow rather than chasing a naturally-aspirated power bump. S&B sells this as a completely separate part number from its TRX intake, the two aren't interchangeable despite the shared platform.
