Every Corsa system is engineered using proprietary RSC (Resonance Sound Cancellation) technology that eliminates drone while maximizing exhaust tone. The 21317BLK is part of Corsa's Cadillac performance lineup, engineered specifically for the twin-turbocharged V6 powertrain in the CT4-V Blackwing with full compatibility with the factory active valve system.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eDoes the Corsa 21317BLK work with the factory active exhaust valve on the CT4-V Blackwing?\u003c\/strong\u003e\n\u003cp\u003eYes. The Corsa 21317BLK is designed to integrate seamlessly with the factory Cadillac Active Exhaust valve assembly. You must retain the OEM active exhaust module for the valve to function correctly. The system gives the driver full mode-dependent sound control from Sport to Xtreme.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between the Corsa 21317BLK cat-back and the 21319BLK axle-back?\u003c\/strong\u003e\n\u003cp\u003eThe 21317BLK is a full cat-back system that replaces all exhaust piping from the catalytic converters rearward, including Corsa's 3.0-inch double X-pipe which improves flow by eliminating the stock crushed piping near the rear axles. The 21319BLK is an axle-back that only replaces the mufflers and tips. The cat-back delivers greater performance and sound improvement.\u003c\/p\u003e\n\n\u003cstrong\u003eWill the Corsa 21317BLK drone at highway speeds?\u003c\/strong\u003e\n\u003cp\u003eNo. Corsa's proprietary No Drone RSC Technology is tuned specifically for the CT4-V Blackwing 3.6L Twin Turbo V6. The system eliminates in-cabin drone at cruise speeds while still delivering an aggressive exhaust note when the driver commands it through the active valve.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the Corsa 21317BLK fit the 2024 and 2025 CT4-V Blackwing?\u003c\/strong\u003e\n\u003cp\u003eYes. The Corsa 21317BLK fits the 2022, 2023, 2024, and 2025 Cadillac CT4-V Blackwing equipped with the factory active valve exhaust system. It is engineered specifically for the 3.6L LF4 Twin Turbo V6 in this generation.\u003c\/p\u003e\n\n\u003cstrong\u003eHow much power does the Corsa cat-back add to the CT4-V Blackwing?\u003c\/strong\u003e\n\u003cp\u003eCorsa's double X-pipe design increases exhaust flow by approximately 10 percent over the stock crushed piping. Exact power gains vary by tune and supporting modifications, but the improved flow delivers measurable increases in high-RPM output for the 3.6L TT V6.\u003c\/p\u003e\n\n\u003cstrong\u003eAre the black tips on the 21317BLK painted or coated?\u003c\/strong\u003e\n\u003cp\u003eThe 4.5-inch tips on the Corsa 21317BLK are Black Pro-Series dual wall slash-cut tips with a black coating. They are the same Pro-Series tip construction used across Corsa's lineup with a black coated finish rather than polished stainless. Surface care with a dedicated exhaust tip cleaner is recommended to maintain the black finish over time.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the Corsa 21317BLK a bolt-on installation or does it require welding?\u003c\/strong\u003e\n\u003cp\u003eThe Corsa 21317BLK is a bolt-on cat-back system with no welding required. Professional installation is recommended to ensure proper fit, alignment, and use of the factory active exhaust module during reassembly.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat warranty does Corsa provide on the 21317BLK?\u003c\/strong\u003e\n\u003cp\u003eCorsa backs the 21317BLK with a lifetime limited warranty covering defects in materials and workmanship. This is one of the strongest warranties in the performance exhaust industry and reflects Corsa's confidence in its domestic manufacturing quality.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eAllow the vehicle to cool completely before beginning installation\u003c\/li\u003e\n\u003cli\u003eLift and secure the vehicle safely on jack stands rated for the vehicle weight\u003c\/li\u003e\n\u003cli\u003eRemove the factory exhaust system from the catalytic converter outlet rearward, retaining all O2 sensor plugs and active exhaust harness connectors\u003c\/li\u003e\n\u003cli\u003eInstall Corsa's 3.0-inch double X-pipe in place of the factory piping near the rear axles\u003c\/li\u003e\n\u003cli\u003eConnect the Corsa system rearward to the muffler sections and align the twin 4.5-inch Black tips within the rear bumper cutouts\u003c\/li\u003e\n\u003cli\u003eReconnect the factory active exhaust module and all wiring harness connectors\u003c\/li\u003e\n\u003cli\u003eTighten all clamps and hangers to factory torque specification\u003c\/li\u003e\n\u003cli\u003eLower the vehicle and start the engine to verify proper seating, absence of exhaust leaks, and correct active valve operation in all drive modes\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"CORSA Performance","offers":[{"title":"Default Title","offer_id":46023839842383,"sku":"COR21317BLK","price":3249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/7920\/files\/corsa-21317blk-cat-back-exhaust-2022-2025-cadillac-ct4-v-blackwing.png?v=1783517279","url":"https:\/\/www.blackopsautoworks.com\/products\/corsa-21317blk-cat-back-2022-2025-cadillac-ct4-v-blackwing","provider":"Black Ops Auto Works","version":"1.0","type":"link"}
