Injen 16-20 Honda Civic 1.5L Turbo 4Cyl (Sedan) 63mm SS Cat-Back Exhaust w/ Dual Burnt Titanium Tips

If you've got a 2016-2021 Honda Civic Sedan with the 1.5L turbo engine and you're looking to add some serious sound and performance, Injen has a cat-back exhaust system that's built for it. This system starts with a large 76mm front section made from 304 stainless steel, which then splits into dual 60mm pipes. Each of those rear pipes is finished off with a striking 3.5-inch burnt titanium exhaust tip, giving your Civic a distinct, aggressive look.

The entire system is constructed from mandrel-bent 304 stainless steel tubing. Mandrel bending is key because it ensures the tubing maintains its diameter and shape throughout its entire length, allowing for smooth, unrestricted airflow. This helps improve exhaust flow, which can lead to noticeable gains in both power and torque – Injen has dyno-proven up to 8 hp and 7 lb-ft of torque with this setup. The system also features a single resonator and no muffler, creating a unique and aggressive exhaust note that you can hear and feel. For added strength and a clean appearance, the investment cast flanges are TIG welded by hand.

This Injen cat-back exhaust is designed specifically for the Sedan models of the 2016-2021 Honda Civic with the 1.5L turbo engine. It's a direct bolt-on system, meaning no cutting or welding is required for installation, and it comes with all the necessary stainless steel hardware and hangers. If you're aiming to improve your Civic's sound, performance, and overall appearance, this system is a solid choice.
