since the early 1990s. The COR21389GNM is part of Corsa's dedicated lineup for the 2025-2026 Ram 1500 RHO, built to match the Hurricane inline-6's unique firing sequence and deliver Sport-level sound through Corsa's patented RSC Technology. Every Corsa system is made in the USA and covered by a Lifetime Limited Warranty.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eDoes the Corsa 21389GNM fit the 2025 and 2026 Ram 1500 RHO?\u003c\/strong\u003e\n\u003cp\u003eYes. The COR21389GNM is designed specifically for the 2025 and 2026 Ram 1500 RHO equipped with the 3.0L Hurricane turbocharged inline-6. It fits Crew Cab configurations and does not fit trucks equipped with the optional GT Package Exhaust.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between the 21389GNM, 21389BPC, and 21389?\u003c\/strong\u003e\n\u003cp\u003eAll three SKUs share identical pipe diameter, muffler design, RSC technology, and Sport sound level. The only difference is the tip finish. The 21389GNM has Gun Metal Pro-Series coated tips, the 21389BPC has Black Pro-Series coated tips, and the 21389 has Satin Pro-Series polished stainless tips. Choose the finish that best complements your Ram RHO exterior.\u003c\/p\u003e\n\n\u003cstrong\u003eWill the Corsa 21389GNM drone at highway speeds?\u003c\/strong\u003e\n\u003cp\u003eNo. Corsa's No Drone RSC Technology is tuned specifically for the Ram 1500 RHO 3.0L Hurricane inline-6 firing sequence. The system is completely silent behind the wheel at cruise and delivers its Sport-level note only under acceleration or on cold start.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21389GNM fit the Ram 1500 Rebel with the 3.0L engine?\u003c\/strong\u003e\n\u003cp\u003eNo. The COR21389GNM is engineered specifically for the Ram 1500 RHO trim. The non-RHO 3.0L Ram 1500 and the Rebel use a separate Corsa exhaust system. Verify trim fitment before ordering.\u003c\/p\u003e\n\n\u003cstrong\u003eHow much does the Corsa 21389GNM improve exhaust flow on the Ram 1500 RHO?\u003c\/strong\u003e\n\u003cp\u003eThe COR21389GNM delivers a 37% improvement in exhaust flow over the factory system. The improved scavenging supports increased top-end output from the 3.0L Hurricane inline-6 and reduces backpressure compared to the restrictive stock exhaust.\u003c\/p\u003e\n\n\u003cstrong\u003eAre the gun metal tips on the 21389GNM painted or coated?\u003c\/strong\u003e\n\u003cp\u003eThe 5.0-inch tips are Gun Metal Pro-Series dual wall flat cut tips with a gun metal coating applied over stainless steel construction. Routine maintenance with a dedicated exhaust tip cleaner helps preserve the finish over time.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the Corsa 21389GNM a bolt-on installation for the Ram 1500 RHO?\u003c\/strong\u003e\n\u003cp\u003eYes. The COR21389GNM is engineered as a direct bolt-on cat-back replacement for the 2025-2026 Ram 1500 RHO. No cutting, welding, or modifications to the factory exhaust hangers or catalytic converters are required. Professional installation is recommended for proper alignment and clamp torque.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat warranty comes with the Corsa 21389GNM?\u003c\/strong\u003e\n\u003cp\u003eCorsa backs the COR21389GNM with a Lifetime Limited Warranty covering defects in materials and workmanship for as long as you own the vehicle. This is one of the strongest warranties available in the performance exhaust industry.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eAllow the Ram 1500 RHO to cool completely before beginning\u003c\/li\u003e\n\u003cli\u003eLift and support the truck safely on rated jack stands\u003c\/li\u003e\n\u003cli\u003eRemove all factory exhaust components from the catalytic converter outlets rearward, retaining all hangers and hardware for reference\u003c\/li\u003e\n\u003cli\u003eInstall the Corsa 21389GNM true dual cat-back, sliding the integrated X-pipe muffler section into position at the converter outlets\u003c\/li\u003e\n\u003cli\u003eRoute both rear pipes over the axle and into position, seating all hangers into the factory rubber grommets\u003c\/li\u003e\n\u003cli\u003eSlide the dual wall 5.0-inch Gun Metal Pro-Series tips onto each tailpipe and adjust for equal depth and rotation within the bumper cutouts\u003c\/li\u003e\n\u003cli\u003eTorque all clamps from front to rear at 45 ft-lbs\u003c\/li\u003e\n\u003cli\u003eLower the truck and start the engine to verify fit, check for exhaust leaks, and confirm Sport-level exhaust tone\u003c\/li\u003e\n\u003cli\u003eRe-check and re-torque all clamps after the first heat cycle once the system has fully cooled\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
