Will the Fabspeed GT3 Conversion Package fit my 997 Carrera?

It fits the 997.1 Porsche 911 Carrera, Carrera S and Carrera 4S from 2005 to 2008, with the 4S from 2006. It is designed for the non-GT3 Carrera models and does not fit the 997.2 (2009 and later), Turbo or factory GT3. Confirm your year and model before ordering.

What is included, and do I need anything else to complete the look?

The package includes the GT3-style center-exit tips, a sport cat X-pipe, and your choice of Maxflo or Supercup side muffler. It does not include the GT3-style rear bumper or a header system. The bumper is what the center-exit tips pass through, so you will need to source a GT3-style bumper separately to finish the conversion.

What does it do for sound and power?

The package gives the 997 a deeper, more aggressive flat-six voice and the center-exit character of a GT3, along with a lift in power from the freer-flowing sport cat X-pipe and performance muffler. Choose Maxflo for a more street-friendly tone or Supercup for a sharper, track-focused sound.

Is installation bolt-on?

Yes. The system is built from 14 to 16 gauge T304 stainless steel and installs as a direct bolt-on that retains the factory muffler location, with no cutting or welding required. Most owners have it fitted at an independent shop, and it is fully reversible.

What is the difference between the Maxflo and Supercup mufflers?

The Maxflo is the mid-level side muffler, tuned for a strong but more livable street sound. The Supercup is the sport option, with a louder, more aggressive, track-focused character. Both mount in the factory muffler position; you select the one that matches how you drive.

Is it CARB approved or emissions legal?

No. The package is not CARB approved and is not for sale or use in California or other states that require CARB certification, even with the sport cat X-pipe. It is intended for closed-course, competition or off-road use where legal. Check your local and state regulations before ordering or installing.

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.
