Confirm your engine before you order
This part is engine-specific and fits the EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS). The photo below shows where to look.
Example plate shown is an EF-NS engine (chassis S100P, 659cc). Yours shows your own code on the same ENGINE line - for this part it must read EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS).
Vehicle Fitment & Compatibility
The Hijet ran several engines in this era. Confirm your engine code on the VIN plate above, not just the chassis, against the table below.

Frequently Asked Questions
How do I know if I have the EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS) engine?
Check the VIN / data plate in the engine bay - the line marked ENGINE shows your code (the example plate above reads EF-NS; yours must read EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS)). This part fits the EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS) engine only, so confirm the code before ordering.
Does this seal kit include the cam or half-moon seals?
Confirm the contents - a valve-cover job often needs the half-moon/cam seals too. Clean both faces to bare metal and torque in sequence.
Which engines does this gasket fit?
It is cut for the listed EF engines - confirm your engine code on the VIN plate before ordering.
Do I need sealant with this gasket?
Most fit dry - only add sealant where the factory manual calls for it. Clean both surfaces to bare metal and torque in sequence.

Not only was it a perfect fit and got my car running again, but during the process of removing it i had broken a piece and was able to send them a text where they responded with a link to order that part. Price may seem high to some of you guys but it is well worth it, it shipped fast and is also the only place to get one without importing.
Nice, high quality exhaust. I like it quite a lot overall. Install was quick and easy, bolted right in, and I was pleasantly surprised that it included a new flange gasket. It's a bit louder than expected, but the sound is good.
Received key blank in a timely manner , had it professionally cut to ensure proper fitment , tried it on the truck anywhere a key is required and ... 'bingo' perfect .
I'm very happy with the exhaust. It sounds great. I was juggling between this one and Special K's behind the bumper exhaust and I ultimately decided on this one. Installation was easy and the only thing I would recommend is getting some washers because the holes on the flange for the growler are ovaled out to allow for adjusting the fitment. Without the washers the flange nuts were just a bit to small.
