Description

SOUL Performance Valved Exhaust System for 991.1 Porsche 911 Carrera / GTS / S (with PSE)

The 991.1 Carrera Valved Performance Exhaust System from SOUL Performance is meticulously crafted with the professional enthusiast in mind. When the valves are open, the exhaust gases are able to flow freely through an unobstructed path, resulting in a captivating flat six symphony that will send shivers down your spine. Whether you’re on your way to an important client meeting or going out for a special dinner, simply keep the valves closed, and you’ll experience a refined and understated tone, as the factory side mufflers effectively carry out their job. For those concerned about drone on their PDK-equipped vehicle, rest assured that this system will exceed your expectations, providing a drone-free experience that leaves no room for disappointment. Many 991.1 Carrera owners find themselves underwhelmed by the sound and performance of their stock sport exhaust system; it simply doesn’t deliver the desired level of satisfaction. In response to this, they have embarked on a mission to create an exhaust system that possesses a true Jekyll and Hyde personality, perfectly aligning with the Carrera’s character of being a wolf in sheep’s clothing. Their primary objective was to design a system that allows for a straight flow path when the valves are open. By employing larger tubing diameter, smooth radius bends, and incorporating an X-pipe with optimized crossover flow characteristics, their exhaust system significantly improves throttle response and performance. These design enhancements maximize the exhaust scavenging effects, leading to increased volumetric efficiency and ultimately enhancing the overall driving experience.

Development & Testing

Their objective was to strike a balance between enhancing the daily driving comfort and preserving the race-inspired tone and straight-through exhaust design. They recognized that simply incorporating a larger resonator would not achieve the desired outcome, as it would necessitate revisions to accommodate clearances and potentially compromise the high-flow design principles of their exhaust system. Moreover, the addition of higher-flowing aftermarket headers, such as their Long Tube Street Headers, to an already aggressive rear system, without proper sound attenuating features, could potentially lead to an excessively loud and potentially unpleasant driving experience.
For customers who have combined their rear exhaust with upgraded headers, it becomes crucial to carefully consider and engineer the exhaust system accordingly. In such a configuration, the inclusion of Helmholtz resonators, also known as anti-drone tubes, can be an effective solution for reducing undesirable frequencies when properly engineered and utilized. In the case of the 991.1 Carrera, there is a specific RPM range, typically between 3,000 and 3,500rpm, where drone may become apparent when higher flowing exhaust components are added. Their objective was to eliminate these unwanted frequencies within that range, while also ensuring a smooth transition from valves closed to open, particularly on vehicles equipped with the factory Porsche Sport Exhaust (PSE) system.
After rigorous testing and refinement, they have arrived at their final design, which has consistently delivered exceptional results on this particular application and met their stringent standards for sound quality and drivability. While the mathematical calculations for creating Helmholtz resonators can be performed, it is the thoughtful incorporation of these resonators into the overall design that truly makes a significant difference in achieving optimal performance.

Construction

Every exhaust is meticulously constructed in-house using mandrel bent T304L stainless steel with a substantial.065″ wall thickness. Once built, each exhaust undergoes rigorous quality checks to ensure its impeccable craftsmanship and performance. The welding process employs back purged TIG welding techniques, guaranteeing optimal weld penetration and ensuring the exhaust’s long-lasting durability.

Sound

The sound produced by their system is undeniably aggressive. One of the primary advantages of their exhaust system is the straight and unobstructed path, allowing exhaust gases to flow freely from the 2.5″ piping to the tips when the valves are open. However, they have also dedicated significant effort to infusing extra refinement into the system, ensuring that it perfectly matches the premium experience synonymous with Porsche.
The inclusion of an X-pipe in both open and closed valve positions further contributes to smoothing out the sound profile. Overall, they are extremely pleased with the results achieved, and they are confident that you will be too. When the valves are open, the system’s free-flowing nature delivers a Cup car-inspired sound, characterized by a greater volume and an abundance of crackles and burbles during deceleration. This system is tailored for those seeking an added level of aggression, accessible with a simple press of a button. Conversely, when the valves are closed, the tone maintains a reasonable and refined quality, ensuring minimal drone while still allowing the distinctive flat six sound to be heard.

Bolt On & Go

After being meticulously tested in a fixture to ensure impeccable fitment, each exhaust is carefully foam packed to guarantee its safe arrival in perfect condition. In addition, comprehensive installation instructions are included in the package, facilitating a straightforward installation process that can be easily carried out by most DIY enthusiasts. High-grade hardware is provided to ensure a reliable and secure installation.
This system seamlessly integrates with the factory Porsche Sport Exhaust (PSE) controls, allowing for convenient control of the exhaust modes. However, it is worth noting that this system can also be utilized on non-PSE equipped S / GTS cars by incorporating a SOUL valve controller kit during installation.

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.
