The downpipe is one of the first modifications installed on a turbocharged Subaru — replacing the OEM downpipe (which contains a catalytic converter that restricts flow) with an aftermarket catted or catless downpipe is a foundational power modification. Every time the downpipe is removed and reinstalled, this gasket must be replaced. Reusing an old turbo-to-downpipe gasket after flange separation is a common cause of post-installation exhaust leaks at the turbo outlet — at $23.80 per gasket, there is no cost justification for reusing the old one.\u003c\/p\u003e\n\n\u003ch3\u003eLocation — Turbo Outlet to Downpipe Inlet\u003c\/h3\u003e\n\u003cp\u003eThe turbo-to-downpipe gasket sits at the turbo’s turbine housing outlet (the downstream\/hot side of the turbo), sealing against the downpipe’s inlet flange. Exhaust gas exits the turbo at this point at high temperature and some residual pressure. A failed gasket here produces an exhaust leak tick or hiss downstream of the turbo, exhaust smell in the engine bay, and can introduce heat near the downpipe routing and surrounding components.\u003c\/p\u003e\n\n\u003ch3\u003eOEM Cross-Reference: 144022AA180\u003c\/h3\u003e\n\u003cp\u003eGrimmSpeed 028001 is a direct replacement for Subaru OEM part number 144022AA180.
