The 2025 Chevy Tahoe and 2025 Chevy Suburban will introduce a mid-cycle refresh for both full-size SUV nameplates, plus a long list of updates and changes as well. Despite this, the refreshed Tahoe and Suburban won’t offer a dual mode exhaust system, despite reports indicating otherwise. Now, GM Authority is reporting the reason why.
For readers who may be unaware, a dual mode exhaust system, also known as an active exhaust system, offers a throatier exhaust tone on demand in conjunction with a specific driving mode. Such a system is available for the 2024 Chevy Silverado 1500 when equipped with the naturally aspirated 6.2L V8 L87 gasoline engine, as GM Authority covered previously.
However, a dual mode exhaust won’t be available for the refreshed 2025 Chevy Tahoe or 2025 Chevy Suburban. To find out why, GM Authority Executive Editor Alex Luft recently spoke with program engineering manager Steve Kersh.
“The Tahoe and Suburban represent a different customer base and what they’re asking for is different [than what Silverado customers are asking],” Kersh told GM Authority.
“We see this from the take-rate on our exhaust accessories that we offer. We do still have the RST Sport package, so there is an offering for those that do want a more sporty sound, sporty offering,” Kersh added.
Currently, the Sport Performance Package is available in conjunction with the 6.2L V8 L87 gasoline engine and features a dual-outlet exhaust system, as well as magnetic ride control suspension. GM also offers the LPO-level (dealer-installed) Cat-Back Performance Exhaust system (RPO code WBC), which includes enhanced sound, plus more power and torque (11 horsepower, 6 pound-feet) and a 30-percent reduction in back pressure. There’s also an optional Borla exhaust system with through-fascia tips.
As a reminder, the refreshed 2025 Chevy Tahoe and 2025 Chevy Suburban will introduce new styling, an overhauled cabin, and the new 3.0L I6 LZ0 turbodiesel Duramax engine as a replacement for the outgoing LM2 Duramax.
