Show original supplier description
The GM Accessories 84888292 is a Chevrolet Performance 6.2L Cat-Back Dual-Exit Exhaust Upgrade System for the Chevrolet Suburban. Constructed from durable 304 stainless steel, this system is designed and validated by Chevrolet engineers to enhance your vehicle's performance and sound. This upgrade system provides a noticeable performance boost, offering up to 11 horsepower and 6 lb.-ft. of torque. It achieves this by reducing backpressure by 31% at 300-g/s, as confirmed by correlated flow testing. The tuning is specifically calibrated to maximize the performance experience while effectively minimizing exhaust drone. For an even greater performance increase, installing this exhaust system in conjunction with the 6.2L Engine Cold Air Intake results in a combined gain of up to 13 horsepower and 7 lb.-ft. of torque. The system is also 50-state emissions legal and is guaranteed not to void the New Vehicle Limited Warranty. This Performance Exhaust Upgrade System includes the rear muffler assembly, Y-Pipe, exhaust clamps, and all necessary mounting hardware for a complete installation. It is noted that this system requires the 6.2L Gas Engine and requires the factory dual exhaust setup. Compatibility is specifically for 2021-2025 Chevrolet Suburban models with the 6.2L V8 - Gas engine. The provided fitment data indicates compatibility with trims such as High Country, LS, LT, Premier, RST, and Z71 for the specified model years and engine.
