Do these Sport Cats for Ferrari 456 fit both the 456 and the 456M?

Yes. Fabspeed's Sport Cats for Ferrari 456 fit every 456 and 456M built from 1992 to 2003, all of which share the 5.5-liter V12. They install as a direct bolt-on over the Factory Equipment, so no cutting, welding, or custom fabrication is needed to fit them to the car.

Will these fix the Ferrari 456 Slow Down warning light?

Often, yes. The 456 Slow Down warning is commonly caused by aging, overheating Factory Equipment. Fitting Fabspeed's high-flow 200-cell sport cats in place of worn factory units restores proper exhaust flow and clears the condition that triggers the warning, provided the oxygen sensors and tune are healthy.

What are the Fabspeed sport cats made from?

They are manufactured from T304L stainless steel and use HJS German EMITEC tri-metallic technology. T304L stands up to the high exhaust temperatures a 5.5-liter V12 generates, which is where the original units tend to fail over time. The 200-cell design flows up to 90 to 93 percent of a straight pipe in most applications.

Will these trigger a check engine light?

No. Fabspeed guarantees no check engine light with these 200-cell sport cats when the vehicle is properly tuned. The HJS tri-metallic technology keeps enough catalytic function to satisfy the factory oxygen sensors, so a correctly set up 456 runs without emissions-related fault codes after installation.

Do the sport cats make the Ferrari 456 louder?

They open up the V12's voice without making the car harsh. The higher-flow 200-cell design lets the 5.5-liter engine breathe more freely, which brings a fuller, more expressive tone and sharper throttle response, while the grand touring refinement that makes the 456 so usable on long drives stays intact.

Can these be shipped to California?

No. These are high-flow aftermarket catalytic converters that are not CARB-approved, so they cannot be sold or shipped to California for street use. Owners in other states, and those running the vehicle off-road or on track where permitted, can fit them freely. Check your local emissions rules before ordering.

Fabspeed Sport Cats for Ferrari 456 and 456M

Fabspeed’s Sport Cats for Ferrari 456 and 456M address a problem every long-term owner of Maranello’s front-engined V12 grand tourer comes to know: the Factory Equipment restricts the 5.5-liter engine, and as it ages it can trigger the dreaded Slow Down warning. Fabspeed builds these 200-cell sport cats from T304L stainless steel at its 26,000 square-foot Pennsylvania facility, using HJS German EMITEC tri-metallic technology that flows up to 90 to 93 percent of a straight pipe in most applications. The payoff is sharper throttle response, a freer and more expressive V12 voice, and a genuine weight saving over the Factory Equipment, all with no check engine light, guaranteed. For a car this rare, it is the considered upgrade that keeps the grand touring experience its owners bought intact.

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.
