Breaking cover back in January at a special media event in Colorado, the next-generation 2021 GMC Yukon introduces a swath of updates and changes for the full-size SUV, including all-new styling. Now, we’re zeroing in on the 2021 GMC Yukon exhaust and what it looks like on the various trim levels.
Looking at all the available trim levels, the range-topping Denali is the only trim to offer a dual exhaust treatment. Meanwhile, the rest of the lineup incorporates a single system with a single outlet exhaust.
The reasoning behind the different 2021 GMC Yukon exhaust treatments boils down to the engines equipped as standard with each of the various trims.
For reference, the dual exhaust on the Denali connects to the naturally aspirated 6.2L V8 L87, which produces 420 horsepower and 460 pound-feet of torque, and is equipped as standard on the Denali trim level. Meanwhile, all other trim levels are equipped as standard with the naturally aspirated 5.3L V8 L84, which produces 355 horsepower and 383 pound-feet of torque, and receives a single exhaust treatment.
What’s more, models equipped with the optional turbodiesel 3.0L I6 LM2 Duramax will also have a single exhaust treatment. The LM2 joins the Yukon engine lineup as a brand-new addition for the 2021 model year, and is offered on every trim level except the new off-roader AT4. Output from the diesel engine is rated at 277 horsepower and 460 pound-feet of torque. As we covered previously, the Yukon’s new diesel engine will have late availability, with production launching 12 weeks after the Start of Regular Production (SORP).
