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.

Description

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.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
