304 Stainless Steel Cat-Back Exhaust Downpipe

This component is crucial for turbocharged vehicles where exhaust flow directly impacts performance. By removing the restrictive honeycomb weave of the catalytic converter and smoothing exhaust flow, this downpipe allows the engine to breathe more freely, resulting in a noticeable increase in power and faster turbo spool. Constructed from premium 100% 304 grade stainless steel, this downpipe features mandrel-bent piping for optimal flow and is meticulously TIG welded by skilled fabricators in the USA. The turbocharger V-Band flange is precisely duplicated and CNC machined from billet 304 stainless steel. It includes CNC machined O2 sensor provisions and laser-cut brackets, with the O2 sensor positioned at the factory location. The design retains the factory donut flange for a 100% bolt-on installation. It is available in multiple finishes, including Brushed, Polished, and Thermal Coated Black, and can be ordered with optional EGT and additional O2 sensor bungs. Use of this racing downpipe may result in check engine lights and fault codes. Race software specific to your vehicle's modifications is strongly advised to optimize performance and drivability. It is prohibited for use on any public highway or any vehicle subject to emissions inspection.
