Product Details

Invidia Catted Downpipe is design with a Divorced Wategate that separate exhaust gas and create a smoother flow. This design is creating more HP and Torque.

The tubing, crafted with 304 stainless steel for longevity, is a 3in mandrel bend piping. It will bolt up to any stock backback or stock replacement unit.

It also comes with a second oxygen sensor bung carefully welded in. This additionnal unit is perfect to install a wideband oxygen gauge sensor while keeping the stock one intact. This second bung comes with a plug, so no worries if you plan to add the wideband oxygen gauge later.

Like most downpipe, you should tune your car on install.
