Soul Performance Header & Muffler Package – 992 Porsche 911 GT3 & GT3 RS (Valved) Compatible with 2022 and newer Porsche 911 GT3 & GT3 RS (992 generation) — select catted or catless at checkout

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

The perfect balance between the Race Exhaust System's all-out aggression and the Valved Exhaust System's refined daily usability — Soul Performance's Header & Muffler Package combines long tube headers with their bespoke valved rear exhaust for a complete system that delivers refined aggression on demand with volume controlled entirely by your right foot. Higher-pitched, smoother sound under all conditions, with a noticeable and satisfying delta between valves open and valves closed.

Soul Performance's bespoke billet CNC merge collectors and long tube runners optimize flow from the headers into a large-diameter X-pipe with valves open, and into a uniquely engineered X-chamber muffler with valves closed — the same muffler design found in their standalone Valved Exhaust System, now benefiting from the dramatically improved header flow path upstream.

Headers Removing the factory headers eliminates the restrictive cat assemblies, particulate filters, and the oversized 7⅝" factory connection point. Soul Performance's billet CNC head flanges deliver a more efficient transition from exhaust ports into the runners while adding extra strength in a high-stress area — preventing cracking from repeated hard use during track days. A bespoke billet merge collector designed from CAD to CNC maximizes runner length and eliminates several welds for improved durability. V-band connection points replace the factory 991-generation connection requiring costly OEM clamps and donut gaskets.

Rear Exhaust Section With valves open, exhaust flows freely through 3" piping and an X-pipe that merges the exhaust banks for a higher-pitched, smooth sound with maximum flow characteristics. With valves closed, exhaust is routed through the bespoke Soul Performance muffler — straight-through perforated piping allows exhaust gases to escape into surrounding packing material with virtually no restriction, while an internal X-pipe allows exhaust flow to merge smoothly. This reduces and smooths drone below 3,000 RPM while enhancing the higher-pitched note Soul Performance was targeting in both valve conditions.

A key engineering detail — even with valves open, some exhaust flow still passes through the secondary muffler path, utilizing it to smooth tone and drone in valves-open mode as well. This allowed Soul Performance to go aggressive on the primary valves-open flow path design without requiring additional resonators or mufflers. Catted and catless sections are interchangeable — a tip plate matching 991 GT3 style allows tip assemblies to be switched at any time.

Valve Control The 992 GT3's electronic valve actuators cannot be simply removed or disconnected — doing so causes check engine lights and performance issues. Soul Performance's included hardware ensures proper valve operation and prevents any chance of issues. Factory valve programming keeps valves closed until 4,000 RPM, gradually opening through 5,000 RPM. For full valve override at wide open throttle regardless of RPM, ECU tuning is available.

Sound A smooth, refined experience from low-RPM casual driving all the way to wide open throttle — higher-pitched and more refined in the low end than a muffler-less system, comfortable below 4,000 RPM with a reasonable level of cabin presence. With valves closed, volume is increased by a refined amount over the dull, hollow factory exhaust note — smoother and more exciting without being overbearing. Aggressive and authoritative when the valves open at 4,000 RPM — a streetable, reasonable level of volume on command compared to a muffler-less system that is loud at all times.

Optional Ceramic Coating Jet-Hot ceramic coating is available for specific configurations at additional cost. Extreme (1300) or Ultra Extreme Heat (2500) coatings can lower surrounding temperatures by up to 65% and protect against thermal oxidation and corrosion. Contact us for a quote.

HJS HD 200-Cell Catalysts Soul Performance uses HJS HD 200-cell catalytic converters — the finest performance catalysts available. The HD design features premium triple-foil winding for maximum strength and a brazing stripe that prevents the core from moving or sustaining damage under sustained high-horsepower use. Meets strict Euro 4 emission standards.

Construction & Quality Soul Performance assembles each system in-house at their Willow Grove, PA facility from mandrel-bent T304L .065" thick-wall stainless steel. Billet 304L stainless steel head flanges and merge collector are precision-cut on a 5-axis CNC machine. Back-purged TIG welding using ARCAL™ Prime argon gas ensures proper weld penetration and long-term durability. Thick-gauge aluminum fixtures are used during fabrication to prevent warping and guarantee perfect fitment. Every set is rigorously quality-checked and foam-packed for safe delivery.

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.

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.

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.
