Overview

Upgrade your 2017-2020 Honda Civic Si with the AWE Tuning Exhaust System Kit, engineered specifically for the Coupe and Sedan 1.5L FWD platform. This is a purpose-built conversion kit that swaps out your existing Track Edition rear section for AWE’s patented drone-canceling solution, delivering a completely straight-through, maximum-performance design without the interior drone that so often ruins highway cruising. If you’ve been searching for a performance exhaust that balances aggression with everyday livability, this AWE catback conversion answers the call.

Key Benefits

At the heart of this exhaust system is AWE’s 180 Technology, a patented approach to drone cancellation that lets you enjoy a straight-through exhaust pipe path for uncompromised flow while eliminating the resonant boom at highway speeds. Constructed from premium T304L stainless steel with 3-inch tubing, this kit is built to endure the elements and deliver lasting, corrosion-resistant performance mile after mile.

Because this is a bolt-on conversion kit, no tune is required to run it, and AWE backs the design with a No CEL Guarantee — meaning no unwanted check engine light after installation. It’s also carries a 50 State Legal voluntary label, so you can run it with confidence wherever you drive. Combined with AWE’s Fit Guarantee, this exhaust system is designed to install cleanly and correctly the first time.

Highlights

  • Patented 180 Technology drone-canceling solution for a quiet cabin at highway speeds
  • Completely straight-through design for maximum performance and flow
  • Durable T304L Stainless Steel construction with 3-inch tubing diameter
  • No tune required — direct bolt-on conversion kit
  • No CEL Guarantee and AWE Fit Guarantee for a hassle-free install
  • 50 State Legal voluntary label

The Conversion Kit Explained

This kit is designed as a conversion for owners who already have the Track Edition rear section installed. Rather than living with the drone that comes with an aggressive straight-through setup, you simply swap the rear section for AWE’s 180 Technology solution and keep the performance while ditching the highway boom. It’s the ideal choice for daily-driven Civic Si owners who refuse to compromise between a serious car exhaust note and long-distance comfort.

Fitment

This AWE Tuning exhaust system kit is engineered for the 2017-2020 Honda Civic Si in both Coupe and Sedan body styles, equipped with the 1.5L engine and front-wheel drive. When you shop for exhaust upgrades for your Si, this AWE catback conversion delivers proven engineering, premium materials, and a guaranteed fit. Whether you’re comparing Borla exhaust, Corsa exhaust, or MagnaFlow exhaust options, AWE’s 180 Technology sets this exhaust system apart with its patented drone-free performance.
