What This Product Does
The plate forms part of the protective arrangement within the GT3 rear bumper assembly. Its position helps control the transfer of heat from the nearby exhaust area to adjacent bumper materials and components.
Functions
- Provides a physical barrier between the exhaust area and bumper assembly
- Helps manage heat around neighbouring rear body components
- Supports the original protective layout of the GT3 rear bumper
- Replaces a missing, corroded or distorted guard plate
Technical Details
- Manufacturer: Porsche
- Part number: 99750581192
- Component type: Guard plate and exhaust heat shield
- Installation position: Rear bumper area
- Application: Porsche 997.1 911 GT3 and GT3 RS
- Model period: 2006–09
Symptoms of Fault
- Visible cracking, distortion or corrosion
- Guard plate missing following bumper or exhaust work
- Rattling or buzzing caused by loose mounting points
- Heat discolouration or marking on nearby bumper components
- Damaged fixings preventing the plate from sitting securely
Why Replacement Matters
A damaged or absent plate can leave nearby bumper materials more exposed to heat from the exhaust area. Replacing it restores the intended barrier and helps maintain the factory arrangement. The mounting hardware, adjoining shields and exhaust alignment should also be inspected during fitting, as loose fixings or incorrect exhaust clearance can cause vibration and unwanted heat exposure.
FAQs
- Where is this guard plate fitted?
It is positioned within the rear bumper assembly close to the exhaust system. - Is this an exhaust component?
It is a protective guard plate associated with the exhaust area rather than a gas-carrying section of the exhaust system. - Can a damaged plate cause a rattle?
Yes. Corrosion, distortion or damaged mounting points can allow the plate to vibrate, particularly at certain engine speeds. - Does it fit every Porsche 997?
The supplied application is for the 997.1 911 GT3 and GT3 RS. Confirm the part number against the vehicle details before installation.

Designed and constructed exclusively for the Porsche 911 GT3 (991) and GT3 RS (991), the Akrapovič dB reducer (Titanium) is aimed at driving enthusiasts who need to keep the noise of the exhaust within approved levels during track-day use. Made from high-grade lightweight titanium, the dB reducer works like an additional muffler to allow extra expansion of the exhaust gases. It is easily fitted by simply removing the Akrapovič tailpipe set and then mounting the dB reducer in place. After installation, the Akrapovič dB reducer (Titanium) reduces dynamic sound levels* by approximately two or three decibels** while still retaining the unique Akrapovič sound and character. It is designed to fit and reduce the measured dynamic sound levels of all Akrapovič systems for the Porsche 911 GT3 (991) and GT3 RS: the Slip-On Line (Titanium), Evolution Line (Titanium), Sports Cup Line (Titanium), and Evolution Race Line (Titanium). The Akrapovič dB reducer (Titanium) is also totally compatible with the optional Akrapovič carbon-fibre diffuser, which is available for the Porsche 911 GT3 (991).
The Akrapovič dB reducer (Titanium) fits also to the stock exhaust system of the 911 GT3 (992) and GT3 RS (992).
*Dynamic sound levels apply to a moving vehicle and not the volume from a static vehicle.
**Noise reduction value is relative (or may vary) due to various noise-measuring methods used and external conditions at different racetracks.
