Do these fit the 992.2 Porsche 911 GTS?

No. They fit the non-GTS 992.2 Carrera, Carrera S, Carrera 4S, and Targa 4S, all of which use the 3.0-liter twin-turbo flat-six. They are not designed for the 992.2 GTS, which uses Porsche's new T-Hybrid powertrain. Confirm your exact model before ordering, and contact Bulletproof Automotive if you are unsure.

What are the GT2 RS Style Outlets, and how do they differ from the standard Sport Cats?

The GT2 RS Style Outlets are a more free-flowing outlet section styled after the GT2 RS, paired with Fabspeed's HJS Sport Cats. Compared with the standard Sport Cats, this configuration flows more and sounds louder and more aggressive, with sharper burbles on deceleration. It is the most free-flowing setup Fabspeed offers while retaining catalytic converters.

Can I run these with the stock muffler, and will they cause a check engine light?

Yes. The system is modular, so the outlets run with the factory muffler or with Fabspeed's Valvetronic Exhaust. An included valve bracket is designed to prevent a check engine light when paired with the stock muffler. The muffler bracket is also offered on its own if you already have the outlets and need the bracket.

How much power do they add?

On an all-wheel-drive Dynojet, Fabspeed measured gains of 23.7 wheel horsepower and 41.5 lb-ft at 3000 rpm, rising to as much as 47.7 wheel horsepower and 47.1 lb-ft at 5300 rpm, roughly 54 horsepower at the crank. The extra flow is felt as quicker turbo spool and stronger pull in comparison to the Factory Equipment.

Is installation difficult?

No. The system is a DIY, bolt-on install that needs no cutting or welding, and it is CAD-designed and laser-scanned for OEM-level fitment. A professional install is still recommended for a car of this value. The outlets also save around 25 pounds versus the factory system.

Are these street legal and CARB approved?

No. Like other high-flow sport catalytic converters, they are not CARB approved and are not legal for sale or use in California. They are offered for off-road and competition use where permitted by law. Fabspeed guarantees no check engine light and the car retains catalytic converters, but buyers are responsible for compliance with local emissions rules.

Description

Fabspeed Sport Cats w/ GT2 RS Style Outlets for 992.2 Porsche 911 Carrera, 4S, S and Targa 4S

Give the 992.2 Porsche 911 Carrera a sharper, motorsport edge with Fabspeed Sport Cats w/ GT2 RS Style Outlets. This setup delivers an aggressive soundtrack with a significant jump in volume over stock, more pronounced turbo spool, and noticeably louder, crisper burbles and pops on decel. Its modular design lets you run the GT2 RS style outlets or swap to the stock muffler or Fabspeed Valvetronic Exhaust while retaining the sport cats. An included valve bracket prevents any chance of the electronic valves triggering a CEL. Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel and laser scanned then CAD designed for perfect OEM fitment using an Ametek Handyscan 700.

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.
