Does the Super Manifold GT-SPEC for ZN6 cars need a tune?

Yes, or an O2 sensor change. HKS states that the stock O2 sensor must be modified unless the car runs the HKS Flash Editor, and no engine management is included. O2 sensor relocation is not possible on manual cars built from August 2016, so owners of those cars should confirm the setup first.

Will it fit an automatic 86, FR-S or BRZ?

Yes, according to HKS. HKS Japan marks the manifold compatible with both manual and automatic cars, with one exception: the later 4BA-code BRZ automatic, which HKS says does not comply with Japanese regulations. HKS gives no other fitment limit for automatic cars.

What happens to the factory catalysts?

HKS builds a compact, high-capacity catalyzer into the manifold in place of the factory first catalyst, and the factory second catalyst stays on the car, so the exhaust still runs two catalysts in total. HKS says the design passes the Japanese exhaust gas regulations.

How much power does it add?

On the HKS dyno against the factory manifold, the Super Manifold GT-SPEC for ZN6 cars gained about 8hp between 3,000 and 4,000rpm and close to 9hp near 6,700rpm. HKS does not state the rest of the test car setup, so treat these as HKS in-house results. It pairs with rear sections such as the HKS Hi-Power SPEC-L II The Bluest Edition or LEGAMAX Premium with Center Pipe.

Is it legal for road use in the United States?

Not as certified by HKS. HKS certifies part 33005-AT007 to the Japanese exhaust gas regulations only and has published no US certification or CARB Executive Order number, so the buyer must confirm road legality locally and treat the part as intended for off-road or competition use.

Description

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

HKS’s Sport Cat Super Manifold GT-SPEC for ZN6 Toyota 86, Scion FR-S and ZC6 Subaru BRZ replaces the factory FA20 exhaust manifold and its first catalyst with a 4-2-1 SUS304 stainless manifold carrying a compact, high-capacity HKS catalyzer. HKS says the factory manifold catalyst restricts exhaust flow, and its own dyno chart shows gains of about 8hp in the mid range and close to 9hp near 6,700rpm.

Development and Testing

HKS chose a 4-2-1 layout for performance and packaged a smaller catalyzer that still clears the Japanese exhaust gas regulations by using more purification material. The renewed layout and catalyzer lower exhaust pressure, which HKS says sharpens acceleration response in the normal rev range and adds power at high rpm, and the Super Manifold GT-SPEC for ZN6 cars is built in SUS304 for strength in circuit use.

Features

4-2-1 layout stepping from 42.7mm to 50.8mm to 60mm
Compact, high-capacity HKS catalyzer built into the manifold in place of the factory first catalyst
SUS304 stainless steel for strength in circuit use

Notes

No engine management is included; HKS says the stock O2 sensor must be modified unless the car runs the HKS Flash Editor, sold separately
HKS Japan says O2 sensor relocation is not possible on manual cars built from August 2016, so owners of those cars should confirm the setup with Bulletproof Automotive before ordering
Dyno gains are HKS in-house figures, and HKS does not state the rest of the test car setup
This manifold is intended for off-road or competition use where emissions laws apply; HKS certifies it to Japanese exhaust gas regulations only, no CARB Executive Order number is published, and the buyer is responsible for checking local regulations

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.
