Catback Exhaust for Cadillac CTS-V Sedan (2009-2014) 6.2L

High-Flow Stainless Steel Mid Pipe for 2009-2014 Cadillac CTS-V

Direct-fit replacement mid-pipe designed to eliminate factory exhaust restrictions and optimize scavenging for the supercharged 6.2L LSA V8.

The Stock CTS-V Exhaust Bottleneck

The factory mid-pipe on the Sigma II chassis CTS-V is notoriously restrictive, utilizing crushed bends, heavy catalytic converter sections, and internal baffling that chokes the supercharged 6.2L LSA engine. As boost pressure increases, this localized restriction causes elevated exhaust gas temperatures (EGTs) and severe backpressure. This structural inefficiency stifles upper-RPM volumetric efficiency, induces heat soak around the transmission tunnel, and fundamentally mutes the aggressive exhaust note inherent to the Gen IV small-block V8 platform.

The Engineering Solution

This upgraded mid-pipe is fabricated from premium T-304 stainless steel, specifically chosen for its superior resistance to thermal fatigue and corrosion in high-heat, high-stress environments. The system transitions cleanly from a 3-inch primary diameter down to a dual 2.5-inch split, maximizing exhaust gas velocity while seamlessly mating to the OEM axle-back assembly. By smoothing the transition radius and removing factory flow disruptions, this mid-pipe dramatically lowers exhaust backpressure. This reduction allows the supercharger to operate more efficiently, lowering EGTs, improving throttle response, and restoring a deep, resonant V8 exhaust signature. Precision welding ensures leak-free performance under load, while the included hardware and gaskets are designed to ensure proper alignment and sealing during installation.
