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

SOUL Performance Products’ Center Muffler Bypass Exhaust for the Porsche 991.1 / 991.2 GT3 turns up the volume on the car’s flat-six soundtrack by replacing the bulky factory center muffler with a lightweight, free-flowing T304L stainless section, all while retaining the side mufflers and factory valves so you can still control volume with the sport button. The result is a richer, more invigorating wail in everyday driving and a true track-inspired tone when paired with upgraded headers, without introducing harshness or compromising daily comfort. Mandrel-bent tubing and quality clamps ensure a precise, direct bolt-on fit that drops roughly 11lb from the rear of the car and integrates cleanly with OEM components. Finished here with 4″ Slash Cut Single Wall tips in Satin Black, the system visually fills out the rear bumper with a purposeful motorsport look that matches the more aggressive exhaust note. Tested in fixtures, foam packed for safe shipping, and backed by SOUL’s renowned Lifetime Warranty for both street and track use, this Center Muffler Bypass is an ideal upgrade for 991 GT3, GT3 RS, and 911R owners who want more emotion, more sound, and less weight in one straightforward package.

Development & Testing

SOUL Performance Products received a request to provide an exhaust system solution that enhances volume and flow, without the need for a substantial financial investment. By retaining the stock side mufflers and valves, you retain the ability to control the sound using the factory sport button. This Porsche exhaust system also complements upgraded headers, offering a combination of power and sound that is ideal for track enthusiasts. Rest assured, the product is backed by our Lifetime Warranty specifically for track use. It is worth noting that no check engine lights were observed during both the development and extensive road testing phases.

Construction

Every exhaust system is meticulously crafted using mandrel-bent T304L stainless steel tubing. To securely mount the system onto the vehicle, Mikalor Supra Heavy-Duty W4 Clamps are provided. These clamps utilize projection welding spots, a swinging bridge, a high-strength stainless steel bolt, and a unique design featuring a captive nut and trunnion, resulting in exceptional clamping forces and long-lasting durability. In addition, AccuSeal clamps are included to connect the exhaust system to the side mufflers, ensuring a secure and reliable connection.

Bolt On & Go

To guarantee flawless fitment, every exhaust undergoes rigorous testing in a dedicated fixture. Furthermore, each exhaust system is meticulously foam packed, ensuring they arrive in impeccable condition. Installing the Center Muffler Bypass Exhaust is a straightforward process, making it suitable for most do-it-yourself enthusiasts to handle with ease.

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.
