Description

SOUL Performance Sport X-Pipe w/ Gillet Flange for 993 Porsche 911 Carrera

SOUL Performance’s Sport Catalytic Converter X-Pipe for the Porsche 993 Carrera (Gillet flange, OBD2) transforms the last air-cooled 911 into a sharper, harder-hitting version of itself while staying emissions-conscious and check-engine-light free. Designed specifically for 1996-1998 cars with Gillet flanges and four O2 sensors, this system packages premium HJS 200-cell catalytic converters into a 2.5-inch T304L stainless X-pipe to cut back pressure, improve scavenging, and unlock a richer, more aggressive flat-six soundtrack. Properly placed OBD2 bungs ensure the ECU reads both banks accurately before and after each cat, supporting consistent power delivery and reliable long-term operation. Thick-wall, mandrel-bent tubing and robust flanges provide durability and heat resistance, while the assembly sheds several pounds versus the factory hardware. Each unit is designed and hand-built in-house, fixture-checked for precise fitment, foam packed for safe delivery, and backed by SOUL Performance’s renowned Lifetime Warranty for confident use on both street and track.

Development

Taking a fresh approach to the 993 Carrera, SOUL examined how they could design superior exhaust components. They opted for a large diameter of 2.5″ piping, which maximizes power gains over the stock system, making it particularly suitable for engine builds with increased displacement. In their OBD1 variants, they implemented a centrally located single O2 bung to ensure the most precise readings from all cylinders. This choice guarantees consistent and optimal performance, as opposed to a compromised system that accommodates both OBD1 and OBD2, where one bung would be plugged and one offset O2 sensor would primarily monitor a single bank of cylinders.

Construction

Every exhaust system is meticulously crafted using robust T304L stainless steel with a substantial wall thickness of 2.5″ and.065″ diameter. The assembly process is conducted in-house with rigorous quality checks at every stage. The utilization of smooth mandrel bends and sturdy flanges guarantees the longevity of the product. To ensure impeccable fitment, each component undergoes thorough testing in a fixture. Additionally, the exhaust systems are carefully foam packed, providing optimal protection during transportation and ensuring their arrival in flawless condition.

HJS Catalysts

SOUL employs the utmost quality catalytic converters, renowned for their exceptional flow and durability within the industry. These converters exhibit remarkable efficiency, enabling compliance with stringent EURO 3 emission standards while simultaneously facilitating increased flow. Moreover, the risk of triggering a check engine light is significantly reduced. The HJS HF design, employed by SOUL, incorporates premium double foil winding, thereby ensuring outstanding strength and durability.

Power

Through independent dyno testing and averaging the results of three runs, it was determined that the peak gains achieved were 8whp and 8ft-lbs of torque. Furthermore, significant power gains of over 15whp can be experienced in the upper midrange, greatly enhancing the overall enjoyment of street driving. It should be noted that these gains can be further amplified with the addition of an ECU tune.

Bolt On & Go

Prior to shipment, each individual product undergoes meticulous testing in a fixture to guarantee flawless fitment. Furthermore, to safeguard its pristine condition upon arrival, the product is carefully foam packed. Inside the package, comprehensive installation instructions are included, ensuring a straightforward installation process that can be easily carried out by most DIY enthusiasts. Additionally, new hardware required for the x-pipe to header flange connection is thoughtfully provided with the product.

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.
