Exhaust Muffler Mounting Kit. Porsche 993 C2 / C4 1994-98

Exhaust Muffler Mounting Kit.
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. Whether your existing hangers are fatigued, rusted or stretched, installing this kit ensures precise alignment, quiet operation and long-term durability.

Fits:

• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97 

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.
  
  

Why Replacement Matters:

• 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.
