The Sound Your Escalade Was Born to Make

The AWE Tuning AWE3015-42321 0FG Dual Exit Exhaust System transforms the 6.2L V8 note on 2021 and newer Cadillac Escalade standard-wheelbase models into a deep, authoritative rumble with zero cabin drone.

A pair of 5-inch double-walled slash-cut chrome silver tips frames the rear fascia cleanly, and the entire system bolts on without cutting, welding, or modifications. AWE backs the AWE3015-42321 with a lifetime warranty, a no check engine light guarantee, and a perfect fitment guarantee, all designed, tested, and manufactured at their facility in Pennsylvania, USA.

Frequently Asked Questions

The AWE3015-42321 is engineered for 2021 and newer Cadillac Escalade standard-wheelbase models equipped with the 6.2L V8 engine. This covers Luxury, Premium Luxury, Premium Luxury Platinum, Sport, and Sport Platinum trim levels. This system is for the standard wheelbase only and is not interchangeable with the long-wheelbase ESV.

AWE's patented 180 Technology uses a tuned resonator that cancels drone frequencies produced at highway cruise RPM ranges, typically around 1,500 to 2,000 RPM. The result is a system that sounds aggressive under acceleration and at idle but remains completely drone-free during long highway drives. AWE backs this with a no-drone guarantee on every 0FG system.

No. This system is a cat-back configuration that connects after the factory catalytic converters, leaving the oxygen sensors and emissions control systems fully intact. AWE guarantees no check engine light on this product. The system is also 50-state emissions compliant, making it legal in all 50 states including California.

The AWE3015-42321 is a direct bolt-on replacement for the factory exhaust on the standard Escalade with no cutting, welding, or fabrication required. Standard hand tools including a ratchet set and penetrating oil for stubborn factory hardware are all you need. Most experienced shops complete the install in two to three hours. AWE provides detailed instructions with the kit.

The factory Escalade exhaust is heavily muffled to prioritize a quiet cabin experience. The AWE 0FG replaces that with a deep, resonant V8 tone that is noticeably more aggressive under throttle input while remaining refined and controlled at cruise. The 3-inch straight-through design improves exhaust flow, which contributes to both the improved sound character and modest power gains.

No. The 42321 part number is configured specifically for the standard-wheelbase Escalade body. For the long-wheelbase ESV, AWE produces separate part numbers with pipe routing matched to that longer body. Installing the standard system on an ESV will result in fitment issues.

AWE's 0FG systems across the product line have shown modest dyno-proven gains from the improved exhaust flow. While AWE has not published specific dyno figures for the Escalade application, the 3-inch straight-through catback design reduces backpressure compared to the restrictive factory system, which typically produces small but measurable gains in throttle response and power across the RPM range.

AWE's Lifetime Warranty covers defects in materials and workmanship for the life of the original purchaser's vehicle. It does not cover damage from improper installation, physical impact, or misuse. AWE also includes a Perfect Fitment Guarantee, meaning if the system does not fit as described on the correct vehicle, AWE will work to make it right. Contact AWE Tuning directly for warranty claims.

The AWE3015-42321 comes with 5-inch double-walled slash-cut chrome silver tips. These are polished stainless steel with a bright chrome-like finish. If you own an ESV, AWE offers ESV-specific systems with chrome or diamond black tips, and a tip-delete version that reuses your factory tips.

Installation Overview

1. Safely raise and support the vehicle on a lift or secure jack stands before beginning work.
2. Allow the factory exhaust to cool completely before handling any components.
3. Spray all factory exhaust clamps and hangers with penetrating oil and allow to soak for 15 to 30 minutes.
4. Disconnect the factory exhaust at the cat-back section, beginning at the rearmost catalytic converter flange.
5. Remove the factory exhaust system from the vehicle, preserving the rubber hanger isolators if they are in good condition.
6. Test-fit the AWE 0FG system by hand, hanging it on the factory rubber isolators before tightening any hardware.
7. Confirm proper clearance to the chassis, fuel tank, spare tire, and surrounding body panels along the full pipe run.
8. Tighten all clamps and hardware to the torque values specified in AWE's included instructions.
9. Start the vehicle and inspect for exhaust leaks at all connection points before lowering from the lift.
10. Allow the system to heat cycle two to three times before checking all hardware for final torque.
