Yes. It is a cat-back system that retains the factory catalytic converters, so it is emission legal in all 50 states. You get the full titanium sound and weight savings without any emissions compromise.

How much power and weight does it change?

On Fabspeed's development car, with the companion Over Axle Link Pipes fitted, the Valvetronic cat-back added 7.5 horsepower at 8,100 rpm and 11 lb-ft at 3,500 rpm, and the full titanium construction saves roughly 10 to 12 pounds over stock. As a naturally aspirated system the main benefits are weight, sound and response rather than a large peak-power jump, and results vary with configuration.

How does it sound, and is it valved?

It retains full factory PSE valve button control. Opened, it delivers a higher-pitched, GT3-like soundtrack toward the 9,000 rpm redline; closed, integrated Helmholtz resonators cancel cabin drone for quiet cruising.

What tip finishes are available?

The tips come in satin black carbon fiber, polished stainless, brushed stainless single wall, brushed stainless turn-down and titanium, so you can match the exhaust to your car.

Is it hard to install?

No. It is a direct bolt-on replacement with no cutting or welding required, so it can be fitted by any competent Porsche shop.

Description

Fabspeed Titanium Valvetronic X-Pipe Cat-Back Exhaust System for 982 Porsche 718 Cayman GT4 RS

Unleash the 982 Porsche 718 Cayman GT4 RS and Spyder RS with Fabspeed’s Titanium Valvetronic X-Pipe Cat-Back Exhaust System, engineered to deliver a higher-pitched wail, significant power gains, and true plug-and-play control via the factory PSE valve button. Developed entirely in house, the system was 3D scanned with a Creaform 700 HandScan, modeled in SolidWorks, and refined through multiple sound revisions and real dyno testing. Fabspeed’s investment-cast X-pipe links the flat-6’s left and right banks for superior scavenging and reduced resonance, while integrated Helmholtz resonators target and cancel drone for a clean, race-bred soundtrack on demand. Lightweight titanium construction, OEM-quality fit, and proven reliability make this the best-sounding, most powerful valved rear section available for the GT4 RS.

Sound

For drivers seeking the GT3’s high-pitched character from a GT4 RS, Fabspeed’s Valved X-Pipe provides the answer. The X-pipe merges the flat-6’s two banks for an intoxicating 9000rpm soundtrack, while the valved design retains factory PSE control to moderate volume and maintain a drone-free cabin when desired. Built from long-run, mandrel-bent titanium tubing, the system minimizes welds and turbulence for superior flow, durability, and finish compared to multi-piece pie-cut constructions.

Power

On Fabspeed’s development car already fitted with Over Axle Link Pipes, the Valved X-Pipe added +7.5hp (+6.2 whp) at 8,100rpm and +11ft-lbs of torque at 3,500rpm. Fabspeed designed and dyno-tested multiple configurations before selecting the optimal system for sound and performance, backed by over 30 years of experience.

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.
