Does the Fabspeed Sport Cat X-Pipe for 997 Porsche 911 Carrera fit the Carrera S, Carrera 4, and Carrera 4S too?

Yes. Bulletproof Automotive lists the Fabspeed Sport Cat X-Pipe for 997 Porsche 911 Carrera for the 2005-2008 Carrera, Carrera S, Carrera 4, and Carrera 4S. If you're cross-shopping fitment, confirm your exact trim before ordering, since Fabspeed's own product page only explicitly documents base Carrera fitment.

How does the Sport Cat X-Pipe differ from a catless X-pipe?

The Sport Cat X-Pipe keeps functioning emissions hardware in place, using integrated 200-cell HJS Sport Cats instead of removing catalytic converters entirely. It's engineered to flow significantly more than the factory system while preserving genuine catalytic scrubbing, so it delivers a meaningful power gain without giving up emissions compliance.

Is the Sport Cat X-Pipe difficult to install?

No. It's a bolt-on X-pipe that mounts in the stock mid-pipe location using factory hardware points, so no cutting or fabrication is required. Most installers complete it in an afternoon in a home garage with the car safely supported, though a lift makes the job easier.

What is the Fabspeed Sport Cat X-Pipe built from?

The X-pipe itself is mandrel-bent T304L stainless steel for accurate bends and unrestricted flow. The integrated catalysts are 200-cell HJS Sport Catalytic Converters, manufactured in Germany by EMITEC, chosen specifically for high flow without sacrificing the catalytic converter's actual job.

How does this compare to Fabspeed's Competition Link X-Pipe for the 997 Carrera?

The Competition Link X-Pipe is a race/off-road-only pipe with no catalysts at all, intended for closed-course use. This Sport Cat X-Pipe keeps genuine catalytic converters in place, so it's the option built for cars that still need to pass emissions or stay street-legal while gaining flow and sound.

Does the Sport Cat X-Pipe come with a warranty?

Yes. Fabspeed backs this X-pipe with its Lifetime Warranty against manufacturing defects, giving buyers long-term peace of mind on the investment. It's also a special-order, made-to-order item rather than a stocked part, so expect roughly one week before it ships once your order is placed.

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.
