Are the Fabspeed HJS Sport Cats a catalyst delete?

No. The Fabspeed HJS Sport Cats are high-flow catalytic converters that keep real emissions scrubbing in place, not a delete or an off-road-only part. They simply replace the dense factory cats with freer-flowing 200-cell HJS units so the engine breathes better after the turbos.

How much power do they add?

Fabspeed projects gains of about 25 horsepower, 30 lb-ft and a 7-pound weight saving, plus faster turbo spool and sharper transient response. The real-world figure depends on your tune and conditions.

Are they emissions legal?

Fabspeed states the HJS cores are certified and homologated to European Tier 6 standards and that the product is EPA compliant, and the cats retain catalytic scrubbing. Emissions rules vary by region, so confirm what your state or country requires before ordering.

Will they throw a check-engine light?

They are optimized to avoid a catalyst-related check-engine light on vehicles with non-monitored gasoline particulate filters. On an Artura with a monitored GPF, a GPF-related light is still possible.

Do they fit the Spider?

Yes. The kit fits both the Artura Coupe and the Artura Spider for the 2021 to 2024 model years, which share the M630 3.0L twin-turbo V6 hybrid.

What are they made of and how big are they?

Each is a 200-cell tri-metallic HJS HD core, 5.15 inches in diameter, the largest that fits the Artura, rated beyond 1,200 hp and flowing roughly 91 to 93 percent of a straight pipe, fed by CNC mandrel-bent downpipe tubing.

Description

Fabspeed German HJS Sport Cats for McLaren Artura

Unlock sharper response and real power gains on the McLaren Artura with Fabspeed’s German HJS Sport Cats, engineered to improve transient boost response while maintaining seamless drivability. Each unit utilizes 200-cell HJS HD German catalysts — chosen for high flow and efficient scrubbing — to out-perform simple cat-bypass pipes where it matters: usable torque, spool, and midrange thrust.

Optimized for maximum performance with no CEL, this is the smart, high-quality upgrade for getting more out of the Artura’s hybrid twin-turbo V6.

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.
