Which Porsche 993 models does this X-pipe fit, and which version do I choose?

It fits air-cooled 993 Porsche 911 Carrera models from 1994 to 1998 with the flat-six. Choose the Bischoff flange for 1994 to 1996.5 cars or the Gillet flange for 1996 to 1998 cars, and pick the OBD1 or OBD2 version to match your car's oxygen sensor setup. Confirm your build date before ordering.

Is this X-pipe street legal?

No. The Race X-Pipe for 993 Porsche is intended for race and competition use only. It is not CARB approved and is not for sale in California or other states requiring CARB certification, and no assessment has been made of EPA anti-tampering compliance. Check your local regulations before any road use.

How much power does it add?

Independent dyno testing, averaged over three runs, showed peak gains of 14 wheel horsepower and 12 pound-feet of torque, with more than 15 wheel horsepower available through the upper midrange. The true 2.5 inch flow path does the work, and owners can expect additional gains once the car is tuned.

Is an ECU tune required?

No. A tune is not required, and the OBD1 and OBD2 configurations are designed so the factory engine management reads balanced oxygen sensor data on your car. Many owners add a tune to unlock more of the X-pipe's flow, but it performs correctly on the stock calibration.

What is the Race X-Pipe for 993 Porsche made from?

The Race X-Pipe for 993 Porsche is built from 2.5 inch, .065 inch wall T304L stainless steel with smooth mandrel bends and thick flanges. SOUL fabricates, fixture test-fits, and quality-checks every part in-house in Willow Grove, Pennsylvania, and backs it with a lifetime warranty covering materials and workmanship for street and track use.

Is professional installation recommended?

Yes. SOUL recommends installation by a qualified technician experienced with air-cooled 911 exhaust work to ensure correct fitment and a leak-free seal at every flange. A professional can also confirm the right flange and sensor configuration for your car and help protect your lifetime warranty coverage.

Description

SOUL Performance Race X-Pipe for 993 Porsche 911 Carrera

SOUL Performance’s Race X-Pipe for 993 Porsche 911 Carrera is a lightweight, free-flowing mid-pipe section for owners taking the last air-cooled 911 to the track or building a dedicated weekend car. Fabricated in-house in Willow Grove, Pennsylvania from 2.5 inch, .065 inch wall T304L stainless steel with smooth mandrel bends and thick flanges, it opens the exhaust path with a true 2.5 inch flow the whole way through and is offered in dedicated Bischoff and Gillet flange and OBD1 and OBD2 sensor configurations so it fits your specific car correctly. Independent dyno testing, averaged across three runs, showed peak gains of 14 wheel horsepower and 12 pound-feet of torque, with more than 15 wheel horsepower on tap through the upper midrange and further gains available with an ECU tune. At 13.9 pounds it saves nearly 10 pounds over the factory section, and it is backed by SOUL’s lifetime warranty.

Development

SOUL built the X-pipe around a true 2.5 inch flow path to free up the midrange and top end on the 993’s flat-six. The OBD1 version uses a single, centrally located oxygen sensor bung that reads more evenly than shared OBD1 and OBD2 layouts, while the OBD2 version carries the full sensor arrangement, so the engine management sees correct data on either car. Dedicated Bischoff and Gillet flange versions match the two factory flange styles used across the 993 Carrera run.

Construction

Each exhaust is assembled by SOUL Performance from thick-wall 2.5-inch diameter, 0.065-inch T304L stainless steel and is rigorously quality-checked in-house. Smooth mandrel bends and thick flanges support long-term durability, and every component is fixture test-fit to confirm proper fitment before being foam packed to help ensure it arrives in perfect condition.

Features

Premium X-pipe with true 2.5-inch large-diameter piping
Increased power and sharper exhaust sound vs factory setup
Bischoff and Gillet flange-specific configurations

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.
