Soul Performance HJS High-Flow Catalytic Converters – 996 Porsche 911 Carrera Compatible with 1999–2004 Porsche 911 Carrera (996 generation) — all models

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

The factory 996 Carrera catalytic converters are one of the most commonly upgraded components on the platform — and for good reason. They're restrictive, they limit exhaust character, and they're holding your flat-six back. Soul Performance's solution pairs their split-bank exhaust design with HJS 200-cell high-flow catalytic converters, delivering more power, a deeper and fuller flat-six sound, and no check engine light.

Soul Performance deliberately chose a split-bank design over an X-pipe after direct sound comparisons revealed that an X-pipe produces a hollower tone that cuts out desirable deeper frequencies on the 996. The split-bank approach adds more volume, more character, and a deeper, fuller flat-six sound with a hint of rasp — almost air-cooled inspired. The difference is immediately noticeable.

HJS 200-Cell Catalysts Soul Performance uses HJS high-flow catalytic converters — widely regarded as among the best available for performance applications. Efficient enough to meet strict Euro 3 emission standards while significantly increasing flow, the HJS HF design uses premium double-foil winding for exceptional strength and durability. Greatly reduces the likelihood of check engine lights while delivering meaningful performance gains.

Construction & Quality Soul Performance assembles each set in-house at their Willow Grove, PA facility from thick-wall .065" T304L stainless steel with smooth mandrel bends and thick flanges for long-term durability. Every set is fixture-tested for perfect fitment and foam-packed for safe delivery. New hardware is included for the cats-to-header flanges.

Warranty

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.
