Does this fit both the 718 GT4 RS and the Spyder RS?

Yes. The system fits both the 982 Porsche 718 Cayman GT4 RS and the 718 Spyder RS, which share the same 4.0-liter flat-six and exhaust layout. Fitment is identical across the two, so the same system is ordered for either car. It does not fit the standard GT4, GTS 4.0, or Spyder.

What is the Fabspeed Valvetronic X-Pipe Exhaust made from?

The Fabspeed Valvetronic X-Pipe Exhaust is built from 14 to 16 gauge CNC mandrel-bent T304L stainless steel, with an investment-cast X-pipe joining the cylinder banks and aerospace-grade Helical valves from the UK. It is a cat-back system that keeps the factory catalytic converters and is emissions legal in all 50 states.

How much power does it add?

On Fabspeed's dyno, measured against a car already running Fabspeed over-axle link pipes, the valved X-pipe added 7.5 horsepower, 6.2 at the wheels, at 8,100 rpm and 11 lb-ft at 3,500 rpm. The gains come from reduced restriction, not from altering the factory cats or engine tune.

Will it drone on the highway?

No. With the valves closed, a Helmholtz resonator is tuned to cancel the frequencies that cause cabin drone, so the car stays comfortable at a cruise. Open the valves through the factory Porsche Sport Exhaust button and the 4.0-liter flat-six delivers its full top-end voice.

What tip configurations are available?

Five configurations are offered: carbon fiber, satin black polished stainless steel, brushed stainless single wall, brushed stainless turn down, and a re-use OEM titanium option that fits the system to your factory GT4 RS tips. All share the same cat-back system, so the choice is appearance. Select your configuration before adding to cart.

Is it emissions legal and will it set a check engine light?

Yes. It is a cat-back system that keeps the factory catalytic converters and is emissions legal in all 50 states and international markets, and Fabspeed engineers it to run without triggering a check engine light. It also installs as a bolt-on with no cutting, using the factory hangers.

Description

Fabspeed Valvetronic X-Pipe Exhaust System for 982 Porsche 718 Cayman GT4 RS & 718 Spyder RS

Fabspeed’s proprietary X-pipe design transforms the GT4 RS’s exhaust note while adding significant power compared to the stock GT4 RS rear exhaust. The X-pipe gives the GT4 RS the same high-pitched wail as the GT3 and integrates seamlessly with the factory exhaust valve system, allowing the driver to quiet the exhaust using the factory PSE button. The design process began with 3D scanning the entire OEM exhaust system using the CREAFORM 700 Handscan, enabling the creation of a complete SolidWorks 3D model. From there, Fabspeed designed the exhaust and fixtures to ensure perfect fitment to OEM standards. After multiple revisions for sound and dyno testing, the decision was made to use Fabspeed’s signature investment cast X-pipe to connect the FLAT 6 engine’s right and left cylinder banks, improving exhaust scavenging and reducing resonance. The system also incorporates Helmholtz resonator technology to eliminate drone by canceling unwanted frequencies.

Sound

Wondering why the GT4 RS doesn’t have the same high-pitched scream as the GT3? The Fabspeed valvetronic x-pipe is the solution! The x-pipe design merges the two exhaust banks, creating an intoxicating 9000rpm symphony. While this system provides a significant increase in volume over stock, the valved design allows for volume control via the factory PSE (Porsche sport exhaust) button, ensuring a drone-free driving experience when desired.

Power

When comparing the development car equipped with Fabspeed’s over axle link pipes, the valved x-pipe added +7.5hp (+6.2whp) at 8100rpm and +11ft/lbs at 3500rpm. Fabspeed designed and dyno-tested multiple systems before selecting the optimal system for both sound and horsepower. With over 30 years of experience, Fabspeed is trusted to deliver top-tier performance upgrades.

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.
