AWE Exhaust Suite for DE4 Acura Integra

The AWE Exhaust Suite for the DE4 Acura Integra was engineered to unlock the full personality of the 1.5L turbo platform with deeper tone, improved flow, and aggressive styling while maintaining everyday drivability. Designed specifically for the DE4 Integra and FE1 Civic Si, this system combines premium materials, straight-through performance engineering, and signature AWE sound tuning into one complete bolt-on package.

Constructed from CNC mandrel-bent, U.S.-sourced .065” wall T304L stainless steel, the system features a unique single 3” to dual 3” catback configuration designed exclusively for the DE4 platform. The included front pipe is engineered to mate perfectly to the factory downpipe connection or compatible aftermarket downpipes designed around OEM fitment, creating a clean and efficient exhaust path from front to rear.

At the center of the system is a bespoke bullet-style resonator that helps smooth exhaust tone while maintaining strong flow characteristics. From there, buyers can choose between two distinct sound profiles: Touring Edition or Track Edition.

The Touring Edition is designed for drivers wanting the perfect blend of aggression and refinement. Featuring AWE’s patented 180 Technology® drone-canceling resonators, the Touring Edition removes unwanted cabin drone at highway speeds while preserving a deep, sporty exhaust note under acceleration. The result is a daily-drivable exhaust with straight-pipe performance characteristics and premium sound quality.

For drivers wanting maximum volume and raw character, the Track Edition removes the rear 180 Technology® resonators in favor of straight sections for a significantly louder and more aggressive sound profile. The Track Edition is intentionally rowdy and delivers an unfiltered exhaust experience throughout the RPM range.

Performance gains are equally impressive, with dyno-proven increases of up to +10 horsepower and +7 lb-ft of torque at the wheels on an otherwise stock vehicle. The free-flowing straight-through design improves throttle response while maintaining factory-like fitment and simple installation without requiring motor mount removal.

Finishing off the system are dual 5” double-walled slash-cut exhaust tips available in Chrome Silver or Diamond Black finishes. Each tip is individually adjustable for perfect alignment and features a stamped AWE logo for a premium appearance.

Every system is backed by AWE’s Perfect Fitment Guarantee, No CEL Guarantee, and Lifetime Warranty, making it one of the most complete exhaust upgrades available for the DE4 Acura Integra platform.
