Description

SOUL Performance Center Muffler Bypass Exhaust System with Straight Satin Black Tips for 991 Porsche 911 GT3 / GT3 RS / R

SOUL Performance Products’ Center Muffler Bypass Exhaust for the Porsche 991.1 GT3 transforms the car’s character by replacing the heavy factory center muffler with a lightweight, free-flowing T304L stainless section that dramatically elevates the signature flat-six wail without sacrificing day-to-day comfort. Retaining the OEM side mufflers and factory valves allows the driver to continue using the sport button to modulate volume, delivering a richer, more emotional tone in normal driving and a true track-inspired roar when paired with upgraded headers. Mandrel-bent tubing, high-quality clamps, and precise bracketry ensure a direct bolt-on installation that sheds roughly 11 lb from the rear of the car while maintaining reliability and avoiding check-engine lights. The included 4″ Straight Cut Single Wall tips in Satin Black visually fill out the rear bumper with a purposeful motorsport look, matching the sharper, more aggressive soundtrack. Backed by SOUL’s renowned Lifetime Warranty for both street and track use, this center bypass is an ideal solution for 991 GT3 owners who want more theater, more sound, and less weight without compromising usability.

Development & Testing

SOUL Performance Products was tasked with providing an exhaust system solution that enhances volume and flow without requiring a significant financial investment. By retaining the stock side mufflers and valves, this system allows drivers to control the sound using the factory sport button, providing a customizable driving experience. Additionally, this Porsche exhaust system is highly compatible with upgraded headers, delivering exceptional power and sound for those seeking the ultimate track setup. The system is backed by a Lifetime Warranty, specifically designed to cater to track use and instill confidence in its durability. Furthermore, no check engine lights were encountered during the extensive development and long-term road testing processes, ensuring a seamless and trouble-free experience for Porsche enthusiasts.

Construction

Every system is meticulously crafted using mandrel-bent T304L stainless steel tubing, ensuring optimal performance and durability. The package includes Mikalor Supra Heavy-Duty W4 Clamps, specifically designed for securely mounting the system to the vehicle. These clamps are equipped with projection welding spots, a swinging bridge, high-strength stainless steel bolts, and an exclusive design of the captive nut and trunnion, delivering superior clamping forces and long-lasting performance. Additionally, AccuSeal clamps are provided to establish a reliable connection between the exhaust and the side mufflers. These high-quality clamps ensure a secure and leak-free joint, further enhancing the overall performance and integrity of the system. With meticulous attention to detail and the inclusion of premium components, each system is designed to deliver exceptional results and exceed expectations.

Bolt On & Go

Every exhaust undergoes meticulous testing in a dedicated fixture to guarantee flawless fitment and optimal performance. To ensure their safe arrival, each exhaust is carefully foam packed for protection during transit, ensuring they reach customers in impeccable condition. The installation process for the Center Muffler Bypass Exhaust is straightforward and user-friendly, making it accessible to most DIY enthusiasts. With detailed instructions included, customers can confidently undertake the installation themselves, enjoying the benefits of the upgraded exhaust system without the need for professional assistance.

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.
