Description

The HPA Motorsports downpipe is a 76mm diameter, T304L stainless steel exhaust component designed for increased flow and reduced back pressure. It features a 100-cell high-flow catalytic converter and a reducer for OEM cat-back fitment. The assembly is precision TIG welded with Argon back purging and includes a CNC-formed hanger and laser-cut flanges.

This results in improved exhaust flow, lower back pressure, and allows the engine ECU to advance ignition and fueling maps more effectively. It also offers substantial weight savings compared to the stock component.
