Muffler Catback Exhaust for Cadillac CTS-V Sedan (2009-2014) 6.2L V8 Engine

Unleash the LSA: High-Flow Dual Muffler Catback System with 4.5" Aggressive Tips

Who It’s For: Engineered specifically for Cadillac CTS-V Sedan owners running the legendary LSA supercharged powerplant. If you’re pushing a 6.2L V8 but your exhaust note sounds more like a luxury cruiser than a 550+ horsepower track weapon, this is the definitive upgrade for your chassis.

The Symptom: The factory exhaust system on the 2009-2014 CTS-V was designed to meet strict NVH (Noise, Vibration, and Harshness) standards, which unfortunately chokes the LSA engine’s natural voice. By using heavy, chambered mufflers and restrictive piping, the OEM setup creates significant backpressure. This backpressure forces the supercharger to work harder to push spent gases out, increasing internal temperatures and parasitic drag that robs you of top-end pulling power and that signature V8 growl.

The Engineering Fix: Our Dual Muffler Catback System utilizes high-velocity fluid dynamics to maximize scavenging. By replacing the baffled factory units with straight-through performance mufflers and mandrel-bent tubing, we eliminate the turbulence found in crushed-bent pipes. The massive 4.5" tips aren’t just for aesthetics; they provide a clean exit for high-volume exhaust pulses, reducing the "bottleneck" effect at the rear of the car. The result is a sharper throttle response, faster boost transition, and an exhaust note that screams under wide-open throttle while remaining refined during highway cruising.

Why Mechanics Choose This Kit

• [Maximum Scavenging]: Increases the flow rate of the LSA engine, allowing the supercharger to breathe easier and reducing heat soak during spirited driving.
• [The 4.5-Inch Aesthetic]: The oversized tips are specifically scaled to fill the factory rear bumper cutouts of the CTS-V, providing a much more aggressive, staggered look.
• [T304 Stainless Integrity]: Built to withstand the extreme EGTs (Exhaust Gas Temperatures) generated by a supercharged 6.2L engine without warping or corroding.
