How much lighter is the SPEC-L II Exhaust for CZ4A than the factory system?

HKS lists the SPEC-L II Exhaust for CZ4A cars at 20.3lb, or 9.2kg, against 44.1lb, or 20kg, for the factory Evo X exhaust, a saving of 23.8lb. HKS reached that by thinning every pipe and silencer rather than removing sound-deadening material, so more than half the weight comes off the rear of the car.

Are the titanium tail covers included?

Yes. HKS changed this series to a titanium tail tip cover in place of the earlier carbon cover, and the cover comes with part 31019-AM111 on both 94mm tails. HKS lists the cover size as 94mm across and 48mm long, which matters to anyone planning to swap covers later.

How loud is the SPEC-L II on an Evo X?

HKS measured 90 dB against 83 dB for the factory system on its close test, and 68 dB against 65 dB at idle. HKS publishes no cruise figure. A 7 dB rise on that test is a clear change, while the idle figure rises only 3 dB over stock.

Does the Evo X need a tune with this exhaust?

No. HKS lists no tuning requirement for part 31019-AM111, and the kit includes no engine management. The 4B11 turbo keeps running on its factory calibration, and owners who already run a tune should tell their tuner about the exhaust change so it can be checked on the next session.

Does the SPEC-L II fit the Evo X Final Edition?

Yes. HKS lists part 31019-AM111 for the 4B11 Lancer Evolution X from 2008 to 2016 and states that it complies with Japanese regulations on the Final Edition. That is a Japanese approval, so US owners should still check the rules that apply where they live.

HKS Hi-Power SPEC-L II Exhaust for CZ4A Mitsubishi Lancer Evolution X

HKS’s Hi-Power SPEC-L II Exhaust for CZ4A Mitsubishi Lancer Evolution X takes more than half the weight out of the rear of the car, at 20.3lb (9.2kg) against 44.1lb (20kg) for the factory system. HKS reached that by thinning each pipe and silencer in SUS304 stainless rather than stripping the sound deadening, and finished both 94mm tails with titanium tip covers. It is built for the Evo X owner who drives on back roads and track days and wants the car lighter, with a clearer and more present voice than stock.

Titanium tail tip covers on both tails, replacing the carbon covers of the earlier series

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.
