Product Details

Invidia Catless 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 must tune your car on install.

Because this downpipe is catless, we must state that this part is intended for off-road use only.
