What are the Fabspeed E9X M3 Sport Cats?

They are high-flow catalytic converters that replace the factory primary cats on the S65 V8 with 200-cell HJS units made in Germany. The HJS catalysts flow much more freely than the dense factory primaries while still cleaning the exhaust, so the engine breathes better through the primary section and the car keeps a catalyst in place.

How much louder are they?

The sound gain is mild and sharp rather than loud. They add a harder edge to the S65 V8's voice and open it up under throttle, but they stay close to stock volume and remain easy to live with on a daily commute, since the primary catalysts are still in place.

Will they trigger a check engine light, and are they street legal?

Fabspeed designs these Sport Cats to run without a check engine light. They are not CARB approved and are not for sale or use in California or other CARB states, and they are intended for off-road or competition use where permitted. Check your local emissions rules before installing.

How much more do they flow?

Fabspeed states that these cats flow up to 90 to 93 percent of a straight pipe in most applications, compared with the much denser factory primary catalysts. That freer flow lets the S65 move more air through the primary section, which is where the gain in breathing and sound comes from.

What are the E9X M3 Sport Cats made from, and what do they work with?

They are built from 14 to 16 gauge T304L stainless steel with CNC mandrel-bent tubing and use German-made HJS 200-cell catalysts. They work with the stock secondary catalysts, or you can pair them with Fabspeed's Secondary Race Pipes for the E9X M3 if you want more flow further downstream.

Is it hard to install?

No. The Sport Cats bolt on in the factory primary location with no cutting or welding, so they reuse the stock hangers and connections. Many owners have them fitted by an exhaust shop, though the job is straightforward for anyone comfortable working under the car.

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.
