Prl Downpipe Civic Si Upgrade for Better Performance

The PRL Downpipe Civic Si upgrade is a game-changer for performance enthusiasts. It can increase horsepower by up to 20 horsepower and torque by up to 15 lb-ft.

This upgrade is designed to work with the Civic Si's turbocharged engine, and its larger diameter piping allows for more efficient exhaust gas flow. By reducing backpressure, the downpipe upgrade enables the engine to breathe better and produce more power.

The PRL Downpipe Civic Si upgrade is also designed to be a direct replacement for the stock downpipe, making installation a breeze. No cutting or welding is required, and it's a great DIY project for those who want to upgrade their Civic Si's performance.

The PRL downpipe for the Civic Si is a game-changer for performance enthusiasts.

By installing the PRL downpipe, you can expect a 400 RPM increase in turbocharger spool.

This results in increased power and exhaust flow throughout the entire powerband.

Decreased backpressure also contributes to cooler exhaust gas temperatures.

Here's a breakdown of the performance gains you can expect:

The PRL downpipe for the Civic Si is a popular upgrade among enthusiasts. It's designed to promote optimal airflow and reduce backpressure.

The kit includes a downpipe assembly, downpipe hardware, and a lower gasket. You'll also get an O2 sensor harness extension, which is a nice touch.

The downpipe assembly is made from 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to a 4.50" OD catalytic converter. This is a high-quality component that's built to last.

The downpipe's length is approximately 20 inches, allowing for a smooth fit and reduced backpressure.

Before starting the installation, consult the vehicle manufacturer's instructions and any relevant local laws or regulations.

The downpipe's flange is designed to fit directly onto the engine's exhaust manifold, eliminating the need for additional adapters.

Ensure the downpipe is securely fastened using the provided hardware, taking care not to overtighten and damage the surrounding components.

The installation process typically takes around 2-3 hours, depending on your level of mechanical expertise and the tools at your disposal.

Double-check all connections and ensure the downpipe is properly secured before starting the engine and taking the Civic for a test drive.
