Invidia's all new downpipe is a great way to start adding Horse Power and Torque gains.

Your car must be tuned to run this downpipe
Because this product replaces/removes an OEM emissions control device we must state that this catless downpipe is for off-road use only.
The 2 bung downpipe also has an extra oxygen sensor bung welded in so you can install a wideband oxygen sensor and keep the stock one intact. It comes with a plug installed so you don't have to worry about not having one
