The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban arrived last month in a joint debut in Detroit, dropping into the full-size SUV segment with a ground-up, next-gen overhaul. Both nameplates feature a long list of updates and changes over the preceding generation, including all-new styling front to back. To that end, the tail sections for both vehicles are equipped with either a single exhaust system, or a dual exhaust system, and now we’re profiling both with the following GM Authority Feature Spotlight.
The different exhaust treatments for the 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban depend on two things: The trim level, and the engine selection.
The trim level cadence for both vehicles are listed as follows:
- High Country
The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban also offer three engine configurations, starting with the standard naturally aspirated 5.3L L84 V8, which is tuned to produce 355 horsepower and 383 pound-feet of torque. Slotting above the L84 is the optional naturally aspirated 6.2L L87 V8, which makes 420 horsepower and 460 pound-feet of torque. Finally, the turbodiesel 3.0L LM2 inline six-cylinder joins the lineup for the 2021 model year, throwing down 277 horsepower and 460 pound pound-feet of torque. Each engine mates to the GM 10-speed automatic transmission.
With all that covered, let’s dive into the 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban exhaust treatments. As stated above, there are two different treatments on offer, including a single system with a single outlet, and a dual system with dual polished stainless steel tips. The single system is standard on LS, LT, RST, and Z71 trim levels, and available on Premier and High Country trim levels when equipped with the LM2 diesel engine. Meanwhile, the dual system is standard on Premier and High Country trims equipped with a gas engine, and not available in conjunction with the LM2 diesel engine or any other trim level.
