Soul Performance Modular Competition Exhaust Package – 991 Porsche 911 GT3 & GT3 RS Compatible with 2014–2019 Porsche 911 GT3, GT3 RS & 911R (991.1 & 991.2) — select valved or non-valved and tip finish at checkout

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

The ultimate exhaust solution for the 991 GT3 platform — and the most flexible. Soul Performance's Modular Competition Exhaust Package is a complete 3-in-1 system combining Side Muffler Bypass Pipes, Center Muffler Bypass Exhaust, and bespoke support brackets into one cohesive package that can be mixed and matched as track conditions or your mood demands. The weight savings are staggering — 46 lbs in the valved configuration, 49 lbs non-valved — and the heat management benefits are just as significant, reducing engine bay heat soak and keeping the rear tires cooler under hard driving.

Soul Performance designed this system to be modular from the ground up, meaning you can run it as a complete package or experiment with different combinations of factory and aftermarket components to dial in exactly the sound level you want. Bespoke support brackets are included because removing both the factory center and side mufflers simultaneously eliminates the factory bracket system — Soul Performance thought of everything.

Configuration Options Two configurations are available — select at checkout:

Non-valved — maximum weight savings (49 lbs), raw and unrestricted GT3 sound throughout the rev range
Valved — retains factory PSE button control for sound management. Valves closed channels exhaust through smaller diameter piping into the center muffler bypass expansion chamber, delivering a notable reduction in exterior sound level with surprisingly civilized cabin presence. Soul Performance considers this the most reasonable cabin presence of any straight-pipe header-back configuration they have experienced on the GT3 platform

Sound The expansion chamber design of Soul Performance's center muffler bypass does an exceptional job reducing drone and vibration in the cabin — making this one of the most liveable full-delete configurations available for the 991 GT3. Mix and match with the factory center muffler or side mufflers at any time to experiment with different sound characteristics and overall volume levels.

Tip Options Soul Performance offers a variety of exhaust tip finishes including double wall tips and single wall stainless steel tips. Logo customization — or no logo at all — is available. Contact us for something special. Note — 991.2 tips are longer than 991.1 tips due to the difference in rear bumper depth, ensuring perfect fitment across all years.

Construction & Quality Soul Performance fabricates each component from mandrel-bent T304L stainless steel tubing. Mikalor Supra Heavy-Duty W4 clamps are included for mounting, along with AccuSeal clamps to connect to the side mufflers. Every component is fixture-tested for perfect fitment and foam-packed for safe delivery. Vacuum line plugs are included for non-valved installations. Installation is straightforward and suitable for most DIY enthusiasts.

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.

Additional Warranty Terms & Legal Disclaimers

This warranty provides you with specific legal rights. You may also have additional rights that vary by state.

Porsche does not authorize any individual or organization to create additional obligations or liabilities beyond those stated in this warranty. Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty. The exclusive remedy under this warranty is the repair or replacement of the defective part.

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.

Some states do not permit limitations on implied warranty duration or the exclusion of incidental or consequential damages — the above limitations may not apply in your state. Additionally, installation of certain parts or accessories may affect your Porsche New Vehicle Warranty. Please consult your authorized Porsche dealer for full terms, or contact us with any questions.
