Invidia Catted Downpipe | 16-21 Civic 1.5T & Si

The Invidia High-Flow Catted Downpipe for the 2016–2021 Honda Civic 1.5T is engineered to reduce post-turbo exhaust restriction, improve exhaust gas flow, and support stronger horsepower, torque, and throttle response.

Constructed from 70mm x 1.5mm 304 stainless steel piping with cast 304 stainless flanges and a 200-cell high-flow catalytic converter, this bolt-on downpipe is built for durability, proper fitment, and improved performance while retaining factory O2 sensor locations.

Tuning is required.
