What is the Valvetronic Designs Exhaust System for 982 Porsche 718 GT4 RS made from?

The Exhaust System for 982 Porsche 718 GT4 RS and Spyder RS is grade 5 titanium throughout, precision TIG welded at every joint, with Inconel heat shielding on the over-axle pipes and burnt titanium tips. Grade 5 is the aerospace alloy, lighter than stainless at equal strength, which is how the system comes in 11.8lbs under the Factory Equipment.

How much power does it add?

Valvetronic Designs quotes roughly 2-4hp for the rear section on its own and 8-10hp for the full system. Those are modest numbers on a car making north of 490hp, and they are not the reason most owners fit it. The sound and the 11.8lbs are.

What is the difference between the three configurations?

The Rear Section carries the large cross-section X-pipe and is the most refined of the three. Adding the over-axle pipes extends the titanium forward, sharpens the tone and raises the volume. The version with Free Flow Headers goes furthest, and it is where the 8-10hp figure comes from.

Does it fit the 718 Spyder RS as well as the GT4 RS?

Yes. Valvetronic Designs lists the system for both the 718 Cayman GT4 RS and the 718 Spyder RS, which share the 4.0-liter naturally aspirated flat-six and the same rear packaging. Confirm the model year with Bulletproof Automotive before ordering.

How are the valves controlled, and is the install reversible?

The valves are vacuum-actuated and the controller is included, so the driver chooses the mode rather than waiting on engine load. Cars from 2020 on reuse the factory valve control. Installation is 100 percent reversible, so the original exhaust can go back on with nothing cut.

Description

Valvetronic Designs Valved Sport Exhaust System for 982 Porsche 718 GT4 RS / Spyder RS

Valvetronic Designs’ Valved Sport Exhaust System for 982 Porsche 718 GT4 RS and Spyder RS is built for the two road cars Porsche came closest to leaving on the grid. Valvetronic designs and builds every system in-house in Boyertown, Pennsylvania, and this one is formed entirely from grade 5 titanium and precision TIG welded, coming in 11.8lbs lighter than the Factory Equipment. A large cross-section X-pipe sits in the rear section, and vacuum-actuated valves with the controller included hand the 4.0-liter flat-six to the driver: composed enough to leave a sleeping street unbothered, and a howling motorsport engine the moment the valves open.

Titanium Construction

The Exhaust System for 982 Porsche 718 GT4 RS and Spyder RS is grade 5 titanium throughout, precision TIG welded at every joint, and 11.8lbs lighter than the Factory Equipment it replaces. That weight comes off the back of a car already built around mass, which is the kind of change a GT4 RS owner feels rather than reads about. The over-axle pipes carry Inconel heat shielding, and the system finishes in burnt titanium tips. Valvetronic Designs backs the titanium tubes and welds with a lifetime of ownership limited warranty.

Sound and Valve Control

Vacuum-actuated valves run the system, and the controller comes in the box. Closed, the tone stays refined and neighborhood-friendly, which matters on a car that spends its weekdays parked and its weekends being used properly. Open, the large cross-section X-pipe lets the naturally aspirated flat-six climb into the howl the GT4 RS was engineered around, an intake and exhaust duet rather than just volume. The change happens on demand, and the whole installation is 100 percent reversible.

Choosing Your Configuration

Three configurations of the Exhaust System for 982 Porsche 718 GT4 RS are offered, and the difference is how far forward the titanium goes. The Rear Section carries the large cross-section X-pipe on its own and is the refined end of the range, worth roughly 2-4hp. Adding the over-axle pipes extends the system forward, sharpens the tone and adds volume. The full setup with Free Flow Headers is the loudest and the most thoroughly changed, worth roughly 8-10hp over the Factory Equipment.

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.
