Description

The 27WON Performance Downpipe is an 80mm catted exhaust upgrade engineered to enhance performance on the 1.5L turbo 11th gen Civic and 5th gen Integra. Constructed with T-304 cast stainless steel flanges and a high-flow 200-cell metallic foil catalytic converter, this downpipe is designed to reduce exhaust back-pressure, leading to increased turbo spool, improved turbocharger efficiency, and greater horsepower gains across the RPM range. It also includes provisions to reuse the factory OEM heat shields and comes with new stainless steel support brackets to prevent downpipe failure. Installation will result in a Check Engine Light (CEL) illumination, and a tune is required to achieve maximum power gains and prevent the vehicle from entering limp mode. Lower support brackets must be used during installation.
