Are titanium tail tip covers included with the SPEC-L II Exhaust?

No. HKS sells the finisher covers for the SPEC-L II Exhaust separately, in carbon as part 34002-AK010, titanium as part 34002-AK013 and Neues Blue as part 34002-AK016. Part 32016-AF101 ships with its standard stainless tails, and each cover is sized to fit the 94mm tail at 48mm long.

How is the SPEC-L II different from the Hi-Power SPEC-L?

HKS designed part 32016-AF101 to meet Japanese regulations and says it is quieter than the Hi-Power SPEC-L, part 32016-BT004. Both are dual-exit SUS304 stainless systems with 65mm piping splitting to twin 50.8mm pipes, but the SPEC-L II uses 94mm tails where the SPEC-L uses 97mm tips.

How much weight does the SPEC-L II save?

HKS lists the system at 25.1lb, or 11.4kg, against 35.7lb, or 16.2kg, for the factory exhaust on the FA24 cars, a saving of 10.6lb. HKS gets there with ultra-thin stainless pipes and silencers, and says the result is close to the weight of a titanium exhaust.

Does the SPEC-L II drone on the highway?

HKS built a silent chamber into the system to keep cabin drone down while stressing a bass tone. HKS does not publish a highway cruise figure, but it lists 88 dB against 82 dB for the factory system on its close test, and 62 to 63 dB against 56 dB at idle.

Does one part fit both the GR86 and the BRZ?

Yes. HKS lists part 32016-AF101 for the ZN8 Toyota GR86 and the ZD8 Subaru BRZ from 2022 on. Both cars share the FA24 engine, and the SPEC-L II Exhaust uses one part number for either badge, so owners do not need to order a separate version for their car.

Is the SPEC-L II approved for one-make racing?

Yes, for the 2025 season according to HKS. HKS lists part 32016-AF101 as a CUP designated part, with T.R.A. approval number T.R.A.230322-154. Series rules change between seasons and between countries, so racers should confirm with their own organizer that the part is eligible before an event.

Description

HKS Hi-Power SPEC-L II Exhaust for ZN8 Toyota GR86 and ZD8 Subaru BRZ

The HKS Hi-Power SPEC-L II Exhaust is the dual-exit SPEC-L II for the FA24 GR86 and BRZ, built from ultra-thin SUS304 stainless pipes and silencers to bring its weight close to that of a titanium system. HKS lists it at 25.1lb (11.4kg) against 35.7lb (16.2kg) for the factory exhaust, and designed it to meet Japanese regulations, so it runs quieter than the HKS Hi-Power SPEC-L. It suits owners who want a lighter dual-exit system with a bass-led note, while racers after the lowest weight can look at the single-exit HKS Hi-Power SPEC-L II Cup Exhaust.

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.
