3.75" Inlet 3.00" Outlet Downpipe

The Street Driven Performance race downpipe is constructed from durable T-304 stainless steel, featuring a 3.75-inch cast inlet and a 3.00-inch cast outlet for enhanced airflow. This component is specifically designed for the 2016-2021 Honda Civic 1.5L engine and is intended to improve overall engine efficiency, particularly when paired with an ECU tuner like Hondata or KTuner. Research indicates that upgrading the downpipe is a highly effective method for boosting the performance of Honda's 1.5L turbo engine.
