This Exhaust Systems Australia left-hand-side manifold cat-converter is listed to fit the Toyota Prado 120 GRJ120R 4.0L V6 (2003-09) and the HiLux GGN15R/GGN25R 4.0L V6 (2005-2015). It is a combined exhaust manifold and catalytic converter for the left bank of the V6.
What is a manifold cat-converter, and why left-hand side?
This part combines the exhaust manifold that collects gas from one cylinder bank with the catalytic converter that treats it, in a single casting. On the 4.0L V6 each bank has its own manifold-cat, so this is the left-hand-side (LHS) unit. The cat sits close to the head so it warms up quickly. Replacing it restores both the gas path and the emissions hardware for that bank.
Why does it cover Prado and HiLux?
Toyota shared the 4.0L V6 across the Prado 120 GRJ120R and the HiLux GGN15R/GGN25R, so one LHS manifold-cat pattern can span both. The listing scopes the Prado to 2003-09 and the HiLux to 2005-2015. Shared engines do not guarantee an identical part across every variant or side, so the application list, year ranges and the LHS designation are the guide rather than the badge.
Will it suit my Prado or HiLux?
It is listed as the LHS unit for the 4.0L V6 Prado 120 (2003-09) and HiLux (2005-2015). Because a V6 has a separate part per bank, make sure you need the left-hand side, then confirm your exact model and year with the workshop before ordering.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits manifold cat-converters in-house across the Illawarra. We confirm the side and the unit against your vehicle, seat the flange gaskets and reconnect the oxygen sensors so the engine reads correctly. Supplied by Exhaust Systems Australia at $380 AUD; send your model, engine and year and we will confirm the right part before booking the bay.
