Product Details

This is the loudest exhaust system available for the 991/991.2 GT3 / RS. This system weighs in at just 8.5 pounds, removing approximately 54-pounds from the rear when compared to a factory 991/991.2 GT3 or 44 from an original GT3RS exhaust system. 

This system replaces the OEM side mufflers and center muffler, as well as the original exhaust tips with aggressive 100mm units. It is compatible with the OEM factory emissions equipment (cats/headers).
* Not Shown - This system also includes original exhaust manifold gaskets (2) for 991/991.2 GT3/RS models, which can be replaced during installation.

The sound is race car LOUD and ultra aggressive. Of course the GT3 engine already sounds magical so this exhaust will showcase its high points. Here is a short video we shot in 2007 (the 991 sounds similar):
Features:
- Three piece, mandrel-bent Stainless Steel construction
- Manufactured in California 
- Uses 3-inch diameter mandrel bent tubing to maximize performance
- Removes heat from side mufflers away from rear tires
- Will not cause check engine lights (when using factory catalytic converters/headers) or effect emissions
- Removes 60 pounds from rear of 997 GT3 or GT3RS, removes 44 pounds compared to Shark Werks Bypass Exhaust
- Removes 54 pounds off of a 991 GT3 & 44 pounds of a 991 GT3RS
- 100% Reversible, no welds or cutting required for installation
- Works with factory ECU tuning (no remapping required)

With software only, the 2010 GT3 went from 392 RWHP to 404 RWHP at the peak. The car gained about this much horsepower for most of its RPM range.
The car gained over 10 ft-lb of torque at its peak around 6600 RPM and more torque throughout the RPM range.
With the exhaust and software, the gains were higher, bringing it up to 414 RWHP at the peak (22 RWHP net gain), more torque at the peak, and a large gain in torque between 3700 and 5400 RPMs.

* This system is not designed for street use, and is only recommended for race tracks where sound restrictions are not in place. It is very loud and will set off nearby car alarms, annoy pedestrians/police/neighbors/wives and possibly make children cry. It may shoot flames at night. Please use responsibly.
** This system will cause a small loss in torque below 3500 RPMs and a gain of approximately 10 HP in higher RPMs.

Application:

  • 911 R - 991
  • 911 GT3 RS - 991
  • 911 GT3 - 991.2
  • 911 GT3 - 991
  • 911 GT3 RS - 991.2

Note: If choosing Black Ceramic Coating option, allow 1-2 weeks additional time for processing. We generally see this as an aesthetic change and not a performance upgrade.

** PLEASE NOTE - We are continuously making changes to some products and it may appear slightly different than shown if ordered due to revisions for strength and fitment.

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.
