This unique dump pipe is made to bolt up to the factory TD05 turbo on a Mitsubishi Lancer EVO 1-3 or E39A VR4. It features a 4-bolt wastegate flange to bolt up an external wastegate. This is a very simple and straight forward method of adding an external wastegate to your EVO – no porting the factory manifold or purchasing expensive new stainless manifold required! Dump pipe outlet is a V-band setup, so you will need to modify the front flange setup of your exhaust system – a simple job done at any exhaust shop.
