Overview

Piping Diameter: 76mm
Mouth Design: Divorced
Catalytic Converter: Yes

Invidia Downpipes are an essential early modification when it comes to increasing your turbocharged vehicles performance. Factory downpipes are very restrictive to your turbo not allowing the exhaust gases to pass through at an ideal rate, Invidia corrects this by incorporating a larger piping diameter and high flow catalytic converters. These factors combined with Invidias unique piping path come together to significantly increase throttle response, horsepower and torque.

Divorced vs. Bellmouth

Divorced: A divorced wastegate downpipe has a plate that protrudes into the turbo to separate exhaust flow coming out of the turbo which in turn reduces turbulence. This is good for stock and smaller turbochargers, some turbos may not allow for a divorced downpipe so it is very important to confirm this if you have an upgraded turbo before making the purchase.

Bellmouth: This design has a wide-open bell at the turbo, which is better for larger turbochargers with more flow. It will work fine with a stock or small turbos, but it is designed for scenarios where wastegate turbulence is not an issue.
