Description
The CORSA Xtreme Valved cat-back exhaust system is configured for Cadillac CT4-V Blackwing. This version pairs 3-inch piping with a dual rear exit layout. This listing includes Polished tips.
Sound and design
Xtreme tuning emphasizes a stronger, more aggressive exhaust character. Consider the rest of the exhaust system when choosing this version: headers, catalytic converters and other changes can alter the final volume and tone. Reflective Sound Cancellation (RSC) technology targets unwanted cruising resonance. The resulting cabin sound depends on the complete vehicle and exhaust configuration.
The cat-back configuration changes the downstream exhaust assembly, making both the forward connection and rear outlet arrangement important when matching the system to the vehicle. Existing aftermarket mid-pipes or rear components should be checked for compatibility.
