2022+ Civic RV6 GESi G-Sport Catted Downpipe for 1.5T & SI

This catted downpipe is one of the most effective upgrades you can make to the 2022+ Civic 1.5T and Civic Si platform. The factory downpipe is heavily restricted to meet noise and emissions targets, which limits how efficiently exhaust gases can exit the turbocharger. This upgraded design replaces that bottleneck with a high flow layout that allows the turbo to breathe properly, improving overall efficiency and responsiveness.

By reducing backpressure directly after the turbo, this downpipe helps the turbo spool sooner and maintain boost more consistently through the powerband. Throttle response improves, mid range torque comes on stronger, and the car feels more eager when accelerating. Power gains are especially noticeable when paired with tuning, but even on a lightly modified setup the difference in drivability is easy to feel.

Sound and Driving Feel

Sound is another area where this downpipe makes a clear impact. Exhaust tone becomes deeper and more aggressive without sounding raw or metallic. Turbo spool is more audible, throttle inputs feel sharper, and under load the car takes on a much more performance focused character. It adds volume and presence while still remaining livable for daily driving when paired with a quality cat back exhaust.

Build Quality and Catalytic Converter

This downpipe is built using high quality stainless steel and precision welds designed to withstand high exhaust temperatures and long term use. Smooth bends and a well sized diameter promote consistent exhaust flow while maintaining excellent fitment.

At the core is a premium GESi high flow catalytic converter. GESi cats are widely regarded as some of the best in the industry, offering excellent flow characteristics while still supporting emissions compliance. This allows you to enjoy the benefits of a performance downpipe without sacrificing reliability or constantly worrying about emissions related issues when properly tuned.
