HKS Sport Cat Super Manifold GT-SPEC for ZN6 Toyota 86, Scion FR-S and ZC6 Subaru BRZ

The HKS Super Manifold GT-SPEC for ZN6 Toyota 86, Scion FR-S and ZC6 Subaru BRZ cars is a 4-2-1 manifold in SUS304 stainless steel with a compact, high-capacity HKS metal catalyzer built into the manifold body. HKS lists pipe diameters of 42.7mm, 50.8mm and 60mm through the layout and targets sharper acceleration response in the normal rev range along with more power at high rpm. It suits a manual FA20 car whose owner is ready to run the HKS Flash Editor or handle the O2 sensor work HKS calls for. For an automatic car, or an owner who wants a bolt-on with no tuning work at all, it is the wrong part.

Features

4-2-1 layout with pipe diameters of 42.7mm, 50.8mm and 60mm
Compact, high-capacity HKS metal catalyzer integrated into the manifold as a sport catalytic converter
SUS304 stainless steel construction that HKS selected for strength in circuit use
Developed for sharper acceleration response in the normal rpm range and added power at high rpm
Special smaller-size catalyzer packaging that keeps the layout compact

Applications

Scion FR-S: ZN6 | 2013-2016 | FA20
Subaru BRZ: ZC6 | 2013-2020 | FA20
Toyota 86: ZN6 | 2017-2020 | FA20

Notes

No engine management is included. HKS states that the stock O2 sensor must be modified unless the car runs the HKS Flash Editor, which is sold separately.
HKS Japan states that O2 sensor relocation cannot be used on manual transmission cars built from August 2016 onward, so owners of later cars should confirm the setup with BA before ordering
For automatic cars, HKS Japan marks most applications of the Super Manifold GT-SPEC for ZN6 and ZC6 chassis as not compatible, so automatic owners should confirm fitment with BA before ordering
Part 33005-AT007 is the GT-SPEC version and is a different part from the HKS Super Manifold with Catalyzer, part 33005-AT006, that BA also lists
This manifold is intended for off-road or competition use where emissions laws apply. The certifications HKS cites are Japanese, no CARB Executive Order number is published, and the buyer is responsible for checking local regulations and confirming road legality.

Frequently Asked Questions

Does the Super Manifold GT-SPEC for ZN6 cars need a tune or other changes? Yes. HKS states that the stock O2 sensor must be modified unless the car also runs the HKS Flash Editor, and no engine management comes with the manifold. HKS also says O2 sensor relocation cannot be used on manual cars built from August 2016 onward, so owners of later cars should plan the setup with BA.
Will this manifold fit an automatic 86, FR-S or BRZ? No, not in most cases. HKS Japan marks the majority of automatic transmission applications as not compatible and lists the Super Manifold GT-SPEC for ZN6 cars mainly for manual transmission models. BA lists fitment for the ZN6 Toyota 86, Scion FR-S and ZC6 Subaru BRZ with the FA20 engine, and automatic owners should confirm their exact car with BA before ordering.
Does HKS recommend the GT-SPEC manifold for a supercharged FA20? No, not on its product page. HKS Japan does not mention forced induction for part 33005-AT007. HKS instead pairs a separate part, the Super Manifold with Catalyzer R-SPEC, part 33005-AT008, with the HKS GT Supercharger System. Owners planning a supercharger should ask BA which HKS manifold suits that build before ordering.
What material is the HKS GT-SPEC manifold made from? The HKS GT-SPEC manifold is made from SUS304 stainless steel, which HKS chose for its strength in circuit use. The 4-2-1 layout runs pipe diameters of 42.7mm, 50.8mm and 60mm, with the HKS metal catalyzer built into the manifold body.
Is the GT-SPEC manifold legal for road use in the United States? No, HKS has not published a US certification or CARB Executive Order number for part 33005-AT007. HKS Japan states that the design passes Japanese exhaust gas regulations only. The manifold is intended for off-road or competition use where emissions laws apply, and the buyer must confirm road legality locally.
