Restore the secure mounting of your rear exhaust muffler system with this mounting kit. Designed for Porsche 911 (993) Carrera 2 and Carrera 4 models, this kit contains all the necessary brackets, clamps, straps and fasteners to correctly mount your muffler to factory specifications.

What This Product Does:
- The muffler mounting kit secures the muffler(s) (rear silencer section of the exhaust system) to the vehicle’s chassis/body under the car.
- It ensures correct alignment of the muffler, holds it in place under vibration, heat cycles and road loads, prevents excessive movement, rattling or contact with the body or suspension.
- Proper mounting safeguards the exhaust system’s integrity: keeps the muffler in the correct position, ensures the hangers/straps are not stretched or damaged, avoids stress on the exhaust pipes, avoids under-body contact and prevents exhaust noise or failure of hangers.
Symptoms & Signs You May Need Replacement:
- Excessive rattling, knocking or vibration under the car at the rear, especially from the muffler area when accelerating, decelerating or going over bumps — a worn/missing mount may allow movement.
- Visible movement or sag of the muffler away from its factory position; misalignment or sagging often means the mountings/hangers are fatigued, corroded or broken.
- Broken, corroded, or missing brackets, straps, clamps or bushings around the muffler mounting area — common on older 993 cars where road salt, heat and age have degraded components.
- Exhaust contact with body or suspension parts — if the muffler shifts due to failed mounting, you may see abrasion marks, burnt body panels or damage to surrounding components.
- Exhaust system repairs or muffler replacement: If you are already replacing the muffler and find mounting hardware is worn, replacing the full kit ensures the new muffler is mounted correctly and reduces future issues.
- Preserves the exhaust system’s function and durability: Proper mounting reduces stress on pipes, joints and the muffler body — which helps avoid cracks, leaks or joint failures.
- Reduces noise and vibration: A secure muffler reduces unwanted movement, prevents rattles and ensures the exhaust system behaves as intended.
- Maintains fit & alignment: On premium cars like the 911 993, correct alignment and mounting of the muffler is part of the overall build quality.
- Prevents damage to other components: A loose muffler may lead to additional damage — for example heat damage to body panels, interference with suspension elements or damage to hanger tabs.
- Cost-effective preventative maintenance: While the muffler may be fine, the mounting hardware often degrades—replacing it when you have access prevents future issues and may save on labour.
