NISSAN PATROL GQ FITTED WITH GENIII 5.7L 6.0L 6.2L (HOLDEN AUTO 4SPEED ONLY) ## MANDREL BENT ## TRI-Y DESIGN ## USE DSF138 ##.
Category: Extractors and headers
This Exhaust Systems Australia mandrel-bent Tri-Y header set (use DSF138 gasket) is listed to fit the Nissan Patrol GQ that has been fitted with a Holden GenIII 5.7L, 6.0L or 6.2L V8 and the 4-speed Holden auto only. It is an engine-swap header set, replacing the manifolds on the transplanted V8.
A Tri-Y header pairs cylinders into two-into-one junctions before joining again, a layout used to separate exhaust pulses on a V8. It replaces the cast manifolds with tubular runners that bolt to the heads at the hottest part of the engine bay and seal with a gasket, listed here as the DSF138. On a swapped engine like this it changes the front of the exhaust at the transplanted V8, not the rest of the Patrol's system.
This is a conversion-specific part: it is listed for a Nissan Patrol GQ that has had a Holden GenIII 5.7L, 6.0L or 6.2L V8 fitted, paired with the 4-speed Holden automatic only. The engine bay routing and gearbox clearance of that exact swap are what the header is cut around, so the gearbox and engine combination matter as much as the vehicle. No power or sound figures are published by the supplier.
It is listed for the GQ Patrol running a GenIII 5.7L, 6.0L or 6.2L Holden V8 with the 4-speed Holden auto. A different gearbox or engine variant changes the fit, so confirm your exact conversion with the workshop before ordering rather than going by the swap in general.
Oak Flats Muffler Men fits engine-swap header sets like this in-house across the Illawarra. We check the runners against your conversion, seat the flanges to the listed DSF138 gasket, and torque them evenly so the joints seal around the swapped driveline. Supplied by Exhaust Systems Australia at $1,320 AUD; tell us your GenIII Patrol build and we will confirm the set first.
