Vehicle Fitment

• 2021-2026 Chevrolet Tahoe (LS, LT, Z71, RST, Premier, High Country - 6.2L V8 L87, Short Wheelbase, 2WD/4WD)
• 2021-2026 GMC Yukon (SLE, SLT, AT4, Denali - 6.2L V8 L87, Short Wheelbase, 2WD/4WD)

Fitment Notes

• Fits short wheelbase models only - Tahoe and Yukon; does NOT fit the Chevrolet Suburban or GMC Yukon XL (long wheelbase), which require AWE SKU 3015-42221 (Chrome Silver) or 3015-43221 (Diamond Black)
• Fits the 6.2L V8 L87 engine only - does not fit Tahoe or Yukon equipped with the 5.3L V8 or 3.0L diesel
• Ball & socket joints on all four tip outlets ensure precise fitment in the factory rear valance across all applicable Tahoe and Yukon trim levels
• For the same short wheelbase fitment with Chrome Silver tips instead of Diamond Black, use AWE SKU 3015-42121

Product Description

The AWE Tuning 3015-43121 is a true dual 3" 0FG catback exhaust system precision-engineered for the 2021-2026 Chevrolet Tahoe and GMC Yukon equipped with the 6.2L V8 L87 engine (short wheelbase), finished with signature quad 4.5" double-walled Diamond Black tips. Front pipes begin directly after the factory emissions equipment, routing to a precision-engineered X-pipe tuned for the 6.2L V8's exhaust character, then through AWE's patented 180 Technology® drone-canceling resonators for a rich, deep V8 tone under throttle and a drone-free cabin at cruise.

Handcrafted from CNC mandrel-bent U.S.-sourced .065" wall T304L stainless steel at AWE's Horsham, Pennsylvania facility, the system installs as a direct bolt-on with no cutting or welding required. The quad 4.5" double-walled Diamond Black tips feature ball & socket joints for precise, flush fitment in the factory rear valance and are stamped with the AWE logo. The system is 50-state legal, requires no ECU tune, and is backed by AWE's Fitment Guarantee, No CEL Guarantee, and lifetime exhaust warranty.
