Description
Overview
Upgrade your 2017-2020 Honda Civic Si with the AWE Tuning Touring Edition Cat Back Exhaust System Kit, engineered specifically for the 1.5-liter, FWD Civic Si in both Coupe and Sedan body styles. Built to bolt directly to your factory catalytic converter, this catback exhaust system delivers a refined, purposeful upgrade over the restrictive stock setup — combining premium materials, smart engineering, and true fitment confidence. If you’ve been searching for a performance exhaust that looks as good as it sounds, this AWE exhaust system is a standout choice.
Constructed from durable T304L stainless steel, this car exhaust is designed to resist corrosion and hold its finish for the long haul. Generous 3-inch tubing keeps flow moving smoothly through the cat-back exhaust, while AWE’s proprietary 180 Technology works to cancel unwanted drone — so you get a clean, controlled sound at cruise without an overbearing cabin buzz. As a Touring Edition, this exhaust is tuned for the driver who wants a mature, high-quality tone that fits everyday driving.
Key Benefits
This is a genuinely street-friendly performance exhaust. It carries a Voluntary Label rating of 50 State Legal, requires No Tune, and is backed by AWE’s No CEL (Check Engine Light) Guarantee along with a Fit Guarantee — meaning it installs and runs clean without triggering fault codes or forcing a re-tune. It’s the kind of exhaust pipe upgrade you can shop for with total peace of mind.
Tip Options & Modular Design
Every kit comes complete with 4.5-inch double-walled, slash-cut tips finished in Chrome Silver, each stamped with the AWE logo. The tips are individually adjustable, so you can set how far they sit into the bumper according to your personal taste. What sets the Touring Edition apart is its modular tip design: this configuration ships with triple 4.5-inch slash-cut tips via AWE’s bespoke stamped tip merges. Thanks to that interchangeability, a dual-tip setup can be converted to a tri-tip configuration — or vice versa — in minutes using an AWE Tip Conversion Kit.
