Key Features

The Honda Civic / Accord / Acura Integra 1.5T Catted Downpipe is designed to bring together world-class engineering, superior material quality, and proven performance. Built from premium T-304 stainless steel, the downpipe features cast ends that ensure excellent fitment, smooth transitions, and reduced turbulence compared to restrictive OEM piping. The centerpiece of this design is the 4.5” 400 CPSI GESi G-Sport catalytic converter, engineered for small-displacement direct injection turbocharged vehicles, capable of supporting up to 850hp without compromising emissions compliance.

One of the most attractive aspects of this downpipe is its plug-and-play functionality. It requires no ECU recalibration or aftermarket tuning, and use of this downpipe will not trigger a check engine light (CEL) in most applications. By upgrading, drivers benefit from increased exhaust flow, lower backpressure, and reduced exhaust gas temperatures—ultimately leading to enhanced throttle response, improved turbo efficiency, and more power across the RPM range.

Compatible with both OEM and aftermarket front pipes, the installation process is simple and requires no additional adapters. For enthusiasts who want a clean, functional, and high-performance upgrade that blends seamlessly with their setup, this catted downpipe delivers in every way.
