Soul Performance High-Flow Catalytic Converter X-Pipe – 993 Porsche 911 Carrera Compatible with 1994–1998 Porsche 911 Carrera (993 generation) — all models — select your configuration at checkout

⚠️ Made to order — please allow 4–6 weeks for production. In some cases, select systems may be available sooner.

The 993 Carrera deserves an exhaust upgrade as thoughtful as the car itself — and Soul Performance's high-flow catalytic converter X-pipe is exactly that. Built around large-diameter 2.5" piping for maximum power gains, this system integrates high-flow catalytic converters directly into a high-quality X-pipe section, delivering meaningful performance and sound improvements without a check engine light. Independent dyno testing revealed peak gains of 8 whp and 8 ft-lbs of torque, with max gains of over 15 whp available in the upper midrange — gains that increase further with an ECU tune.

Soul Performance engineered unique solutions for the several flange combinations found on 993 models — Bischoff and Gillet — as well as OBD1 and OBD2 variants, ensuring the ECU receives accurate, balanced O2 sensor readings from all cylinders regardless of your specific configuration.

Power & Performance Independent dyno testing across three averaged runs confirmed peak gains of 8 whp and 8 ft-lbs of torque over the factory system, with maximum gains exceeding 15 whp in the upper midrange — making everyday street driving noticeably more engaging. Pair with an ECU tune for even greater results. The 2.5" diameter piping is also ideal for engine builds increasing displacement.

O2 Sensor Engineering Soul Performance's OBD1 variants use a centrally located single O2 bung for the most accurate readings from all cylinders — a deliberately superior design compared to systems built around both OBD1 and OBD2 simultaneously, where one bung would be plugged and an offset sensor would monitor primarily from one bank. Consistent, accurate readings across all cylinders means consistent, reliable performance.

Construction & Quality Soul Performance assembles each system in-house at their Willow Grove, PA facility from thick-wall 2.5" diameter .065" T304L stainless steel with smooth mandrel bends and thick flanges for long-term durability. Every component is fixture-tested for perfect fitment and foam-packed for safe delivery. New hardware for the X-pipe to header flange connection is included. Thorough installation instructions are included for a straightforward DIY install.

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

  • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
  • Warranty claims must be processed in person at an authorized Porsche Service Center
  • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
  • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
  • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

  • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
  • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
  • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
  • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

  • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
  • A completed warranty certificate
  • Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.
