This OE Match exhaust strap bolt is a direct replacement for the original Porsche fastener used to mount the muffler retaining strap. Designed to factory specifications, it features a pan-head M8 x 50mm configuration, ensuring proper fitment and secure fastening
This component is specifically used in conjunction with the exhaust muffler strap (e.g. 99311111907) to hold the silencer firmly in place, maintaining correct exhaust alignment and structural integrity.
This bolt secures the muffler strap to the mounting point, ensuring the exhaust silencer remains properly positioned. It helps prevent movement, vibration, and misalignment of the exhaust system during operation.
Function
• Secures exhaust muffler strap to chassis mounting point
• Maintains correct positioning of exhaust silencer
• Prevents loosening under vibration and heat cycles
• Supports stable and secure exhaust system mounting
• Ensures long-term fastening reliability in high-temperature conditions
Exhaust fasteners are exposed to extreme heat, moisture, and road debris, which can cause corrosion, seizure, or thread damage. A worn or incorrect bolt may lead to loose exhaust components, increased vibration, or misalignment. Replacing it ensures secure fastening and proper exhaust system stability.
When to replace
• During exhaust or muffler strap replacement
• Bolt is corroded, seized, or damaged
• Loose or rattling exhaust components
• Signs of thread wear or stripped head
• Preventative replacement during exhaust maintenance

Titanium is a highly corrosion-resistant material, which is particularly important in exhaust systems due to the exposure to extreme heat and moisture. The corrosion resistance of titanium bolts ensures longevity and reduces the risk of premature failure, ultimately saving the owner from costly repairs.
