Does the SPEC-L II Exhaust for VA include the center pipe?

Yes. HKS supplies the SPEC-L II Exhaust for VA cars, part 31019-AF130, as the center pipe plus both rear mufflers, and lists the set at 22.9lb, or 10.4kg, which HKS rates 54% lighter than the factory system. It bolts up with the factory springs, bolts, gasket and rubber hangers.

Does the SPEC-L II fit the US-market WRX STI?

Yes. The HKS USA release sheet for part 31019-AF130 lists the WRX STI with the EJ257 alongside the WRX with the FA20 turbo, from 2015 on, and HKS Japan registers it for the VAB STI as well. The HKS USA product record names only the WRX, so this listing follows the release sheet.

How loud is the SPEC-L II on a WRX and an STI?

HKS measured 82 dB against 74 dB stock on a Japanese-market WRX S4 with the FA20 turbo, and 89 dB against 78 dB on a Japanese-market STI, with 67 dB against 60 dB at idle. HKS publishes no cruise figure, so expect a clearly more present note, most of all on the STI.

Does the WRX need a tune after installing the SPEC-L II?

No. HKS lists no tuning requirement for part 31019-AF130, and the kit includes no engine management. Both the FA20 turbo and the EJ257 keep their factory calibration with the exhaust fitted, and owners planning a tune later can keep this system and tell their tuner about it.

How much ground clearance does the SPEC-L II have?

HKS lists 125mm of minimum road clearance, measured at the mid silencer on the center pipe with stock suspension. Owners on lowered springs or coilovers should measure their own ride height and take care on steep driveways, as clearance on a given car can differ from the HKS figure.

Description

HKS Hi-Power SPEC-L II Exhaust for VA Subaru WRX and WRX STI

HKS’s Hi-Power SPEC-L II Exhaust for VA Subaru WRX and WRX STI replaces the center pipe and both rear mufflers on the 2015-2021 sedan, and HKS lists the set at 22.9lb (10.4kg), 54% lighter than the factory system. HKS reached that figure by thinning every pipe and silencer rather than pulling out sound-deadening material, so the SUS304 stainless system keeps a finished dual-exit rear with a 94mm tail on each side. It is a weight-first upgrade for a VA that sees autocross days and back roads, and a loud one on the EJ257 STI.

Center pipe and both rear mufflers supplied together
Weight cut by thinning each pipe and silencer, which HKS puts at roughly half the factory system
Installs with the factory springs, bolts, gasket and rubber hangers
Dual-exit rear that HKS styled for a more aggressive look

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.
