Cat Back Exhaust Kit w/3.5"OD Muffler Tip For Cadillac Escalade/GMC Yukon (2009-2013) with 6.2L V8 Engine

Unleashing the L92 & L94: High-Flow Performance Cat-Back Exhaust for the 6.2L V8

Who It’s For: Engineered for 2009-2013 Cadillac Escalade and GMC Yukon owners running the legendary 6.2L Gen IV Small Block V8 who are tired of the muted, restrictive factory tone and sluggish low-end torque.

The Symptom: The factory exhaust system on the GM GMT900 platform is designed for near-silent operation, which unfortunately comes at the cost of performance. To achieve this silence, the OEM exhaust utilizes heavy, baffled mufflers and multiple restrictive resonators that create significant backpressure. This bottleneck forces the engine to work harder to push out spent gasses, resulting in a "lazy" throttle feel and a lack of the signature V8 growl that a 376 cubic inch engine deserves.

The Engineering Fix: This Cat-Back Exhaust Kit transforms the 6.2L powerplant by optimizing exhaust scavenging. By utilizing mandrel-bent tubing and a high-velocity 3.5" OD muffler tip, we eliminate the turbulent "crush bends" found in stock piping. This smoother path allows for a higher rate of gas flow, reducing the pumping losses of the pistons. The result is a more efficient combustion cycle, improved volumetric efficiency, and a significant increase in the exhaust note’s depth and clarity.

Why Mechanics Choose This Kit

• Enhanced Scavenging: Reducing backpressure allows the L94/L92 engine to breathe better, translating to noticeable gains in towing torque and high-end passing power.
• The 3.5" Signature Sound: Delivers a deep, aggressive V8 rumble that reflects the premium nature of the Escalade and Yukon Denali without the obnoxious drone of lower-quality kits.
• Precision Construction: Built to withstand the heat and vibration of heavy-duty SUV use, featuring a 3.5-inch outer diameter tip for a bold, custom aesthetic.
