The AWE Tuning Touring Edition Exhaust, part number 3015-39331, is engineered for the FE1 Honda Civic Si and DE4 Acura Integra. This 3-inch downpipe-back exhaust system delivers straight-through performance, a deep and refined exhaust note, and minimal cabin drone at highway speeds. Designed for enthusiasts who want stronger sound and performance without sacrificing everyday drivability, the Touring Edition is a versatile upgrade for street-driven vehicles.

Constructed from CNC mandrel-bent, U.S.-sourced 0.065-inch wall T304L stainless steel, the system features an integrated front pipe, a bespoke midpipe with bullet-style resonator, and a single-to-dual exhaust layout. AWE’s patented 180 Technology® resonators are positioned at the rear to cancel drone-prone frequencies and keep the exhaust character focused behind the vehicle. The clean, straight-through design helps maximize flow while maintaining a sophisticated tone.

The AWE Tuning 3015-39331 is designed as a direct bolt-on upgrade for factory-like installation and includes dual slash-cut, double-walled 5-inch tips finished in Vapor Blue. The system is also engineered for guaranteed fitment and includes AWE’s No CEL Guarantee. When paired with the factory downpipe, the 3-inch cat-back configuration installs without major modifications; a separate 3-inch to 3-inch adapter is required for applicable downpipe upgrades. Claimed maximum gains reach up to 10 horsepower and 7 lb-ft of torque at the wheels. Backed by a limited lifetime warranty, this exhaust system offers durable construction and long-term performance for Civic Si and Acura Integra applications.
