Does the SOUL Valved Exhaust System for 981 fit my Boxster Spyder or Cayman GT4?

Yes. This system fits the 981 Porsche Boxster Spyder and Cayman GT4 from 2015 to 2016, and the Cayman GT4 Clubsport from 2016, all with the 3.8L flat-six. It is a direct bolt-on over-axle system designed for the 981 platform, so no cutting or fabrication is needed.

How does the valved exhaust change the sound?

With the valves closed, the Valved Exhaust System for 981 keeps a refined tone with minimal drone at highway speed, so the car stays comfortable to drive every day. Open the valves and the perforated mufflers let the 3.8L flat-six breathe into an aggressive, high-revving voice. You get a quiet cruiser and a track-ready soundtrack from one system.

How are the valves controlled?

The valves are operated by the factory valve button, so the system works just like the stock setup. It is also compatible with SOUL's valve controller fobs and with HomeLink, giving you remote control over the exhaust mode. You can open or close the valves on the fly, whenever you want a quieter or louder tone.

Will it drone on the highway, especially with headers?

No, drone control was SOUL's top priority in the design. The perforated, sound-deadened mufflers keep the closed-valve tone civil at highway speed, even on a car running free-flowing headers. Open the valves for aggression on back roads and track, then close them for a calm, low-drone cruise home.

What tip options are available?

You can choose single wall 321 stainless tips in Signature Satin, Satin Black, or Brushed, in a straight cut or slash cut style, with lightweight titanium also offered. Dual wall chrome tips are available in Polished Chrome or Black Chrome. Select your tip style and finish from the options before adding the system to your cart.

What is it made from, and is it covered?

The system is mandrel-bent T304L stainless steel with 2.5-inch over-axle piping and 321 stainless tips, hand-built and fixture-tested for fitment. It is backed by SOUL's lifetime warranty to the original owner, covering materials and workmanship for both street and track use. Professional installation is recommended for the best fit and seal.

SOUL Performance Valved Exhaust System for 981 Porsche Boxster Spyder and Cayman GT4

SOUL Performance’s Valved Exhaust System for 981 Porsche Boxster Spyder and Cayman GT4 gives the 3.8L flat-six two personalities on demand, composed and quiet for the commute, loud and full when you want it. With the valves closed, SOUL’s perforated, sound-deadened mufflers hold a refined tone with minimal drone at highway speed, even on a car running free-flowing headers; open the valves from the factory button and the system breathes into an aggressive, high-revving flat-six voice. SOUL hand-builds the system in Willow Grove, Pennsylvania from mandrel-bent T304L stainless steel, with 2.5-inch over-axle piping and 321 stainless tips, and it bolts straight on with no cutting. Valve control runs off the factory button, SOUL’s own fobs, or HomeLink, so switching modes is effortless. Choose your tips, from brushed, signature satin, and satin black single wall to lightweight titanium, or dual wall chrome in polished or black chrome, all backed by SOUL’s lifetime warranty.

Development

SOUL built this system with one priority at the top, minimal drone at highway speed, which is the complaint that pushes owners away from an aftermarket exhaust. The perforated muffler design lets the exhaust gases work with the muffler when the valves open for a fuller sound, while the sound-deadening packing keeps the closed-valve tone civil for daily driving. The result holds up whether you run the factory headers, SOUL’s high-flow Sport Cat street headers, or the free-flowing competition headers.

Construction

The system is built from mandrel-bent T304L stainless steel with 2.5-inch over-axle piping for smooth, high flow. The mufflers use fortified casings with sound-deadening packing and a perforated core, and the tips are 321 stainless steel, with titanium single wall tips available to save nearly a pound. Every system is fixture-tested for fitment and foam packed before it ships.

Bolt On and Go

The exhaust installs as a direct bolt-on with instructions included and no cutting required. Valve control works with the factory valve button, SOUL’s valve controller fobs, and HomeLink, so you open and close the valves exactly as you would from the factory.

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.
