Description
Overview
The AWE Tuning 17-20 Honda Civic Si (Coupe/Sedan, 1.5, FWD) Exhaust System Kit is a Touring Edition Cat Back exhaust system engineered specifically for the tenth-generation Si. Built entirely from T304L Stainless Steel with 3-inch tubing, this performance exhaust delivers a refined, motorsport-inspired upgrade over the restrictive factory setup while keeping everyday drivability intact. If you have been searching to shop for exhaust hardware that combines precision fitment with premium construction, this borla-and-corsa-class contender from AWE brings a genuinely tailored solution to the table.
Key Benefits
This Touring Edition catback exhaust is designed as a complete, integrated system. The front pipe is built directly into the exhaust design, so the entire car exhaust works as a matched unit rather than a patchwork of mismatched components. AWE deliberately reused the factory-style flange and gasket for reliability and long-term performance. The factory double-layer steel gasket is fully captured by a machined groove in the flange, eliminating the possibility of blowout or deterioration over the long haul. Unlike a flat aftermarket gasket that can stick and tear on removal, this design remains fully serviceable.
Because it is a valveless system, you get consistent, no-fuss operation with no compromise on quality. It carries a No CEL Guarantee and a Fit Guarantee, requires no tune, and is backed by AWE’s 180 Technology for controlled sound tuning. The Voluntary Label confirms it is 50 State Legal, making it a smart, compliant exhaust system choice.
Tip Options & Media
Every exhaust comes complete with 4.5-inch double-walled, slash-cut tips finished in striking Diamond Black, each carrying a stamped AWE logo. The tips are individually adjustable, so you can dial in exactly how far they sit into the bumper to match your personal taste. The Touring Edition’s modular tip design lets you run either double or triple 4.5-inch slash-cut tips via AWE’s bespoke stamped tip merges. That means a dual-tip configuration can be converted to a tri-tip setup (and back) in minutes, giving you the flexibility to change the look of your Si whenever you want.
Fitment
This exhaust pipe system is engineered for the 2017-2020 Honda Civic Si in Coupe and Sedan body styles with the 1.5L engine and FWD layout. Note that AWE exhausts are not designed to mate with other aftermarket front pipes, since the front pipe is integrated into the system for guaranteed sealing and performance.
