Product Description

Unleash more sound and improve exhaust flow from your Cadillac CT5-V Blackwing with the CORSA Performance 3.0" Double X-Pipe (21321). Designed specifically for the supercharged 6.2L V8 Blackwing, this mid-pipe replaces the restrictive factory section with a full 3.0-inch dual-crossover design, eliminating the crushed factory piping near the rear axles.

The dual X-pipe configuration improves exhaust-gas crossover and scavenging while giving the Blackwing a more aggressive exhaust character. One of the most noticeable changes is during deceleration and downshifts, where CORSA says the enhanced scavenging produces significantly more crackles and burbles.

CORSA reports approximately a 2% increase in exhaust flow from the Double X-Pipe. It can be used as a standalone upgrade to improve the factory exhaust or paired with CORSA's valved exhaust components for a more complete performance exhaust package.

Product Features

  • 3.0-Inch High-Flow Construction – Replaces the restrictive factory mid-pipe section with full 3.0-inch piping designed around the Blackwing's high-output exhaust requirements.

  • Double X-Pipe Design – Two crossover points improve exhaust-gas interaction between the left and right banks for enhanced scavenging and a more refined performance exhaust note.

  • Eliminates Crushed Factory Piping – CORSA specifically designed the 21321 to replace the flattened factory exhaust sections near the rear axle, removing a restriction from the OEM exhaust path.

  • More Crackles & Burbles – CORSA says the enhanced scavenging effect of the dual crossover produces considerably more audible crackles and burbles during deceleration and downshifts.

  • Approximately 2% Increased Flow – CORSA reports improved exhaust flow compared with the factory configuration.

  • USA Engineered & Manufactured – Designed and manufactured in the United States and backed by CORSA's Lifetime Warranty.

Why Upgrade?

The CT5-V Blackwing's supercharged V8 already has an impressive factory exhaust system, but the OEM piping includes flattened sections near the rear axle that reduce the available cross-sectional area. CORSA's 21321 replaces this portion with a full 3.0-inch Double X-Pipe, providing a smoother, less restrictive exhaust path.

The upgrade isn't only about flow. The dual-crossover arrangement changes the way exhaust pulses from each bank interact, creating the enhanced scavenging effect CORSA specifically targeted during development. The result is a more aggressive exhaust character, with the difference particularly noticeable during downshifts and deceleration.

This also makes the 21321 an excellent first exhaust modification for a Blackwing owner who wants more character without immediately replacing the entire factory valved exhaust. For owners looking for the complete CORSA setup, this same 3.0-inch Double X-Pipe architecture is incorporated into CORSA's Xtreme Valved Cat-Back system for the CT5-V Blackwing.

Remove the restrictive factory piping and let the Blackwing's supercharged V8 come alive with CORSA's 3.0-inch Double X-Pipe—more flow, stronger scavenging, and noticeably more crackles and burbles.
