Soul Performance Complete High-Flow Exhaust System – 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's air-cooled flat-six is one of the most characterful engines ever fitted to a road car — and it deserves an exhaust system worthy of that legacy. Soul Performance's complete high-flow exhaust solution combines HJS 200-cell catalytic converters built into a high-quality X-pipe section with a large-diameter, non-restrictive muffler bypass rear exhaust — delivering an incredible air-cooled chorus that honors everything that makes the 993 special. At 25 lbs lighter than the factory system, this is a meaningful performance and weight reduction upgrade in addition to the dramatic sound improvement.

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.

Sound Crackles and pops on downshifts, a wonderful burble at idle, and a roar under hard acceleration that lets everyone around you know your Porsche is something special — without ever becoming overbearing in the cabin during longer drives. The HJS catalytic converters and X-pipe keep the engine note clean and free of rasp despite the dramatically increased flow. Civilized at low throttle and low RPM, absolutely alive when you want it to be. Soul Performance describes it perfectly — it's air-cooled, of course it sounds great.

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

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.

Worst Fitting Exhaust Ever ( Verified Buyer )

5 out of 5 stars.

Aaron Lujan (Arizona) | June 14th, 2025

This is the worst fitting exhaust I’ve ever purchased. There were missing parts that Soul forgot to send then I had to get on the phone with them because they weren’t understanding my issue. I ended up sending the exhaust back to Soul for some adjustments. The mounting bracket on the driver side bypass pipe is too long and the pipe doesn’t line up properly. The cats barely line up with the hanger bracket. Ended up putting the stock exhaust back on the car. Waste of money and time.

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.
