Why Replace Your Exhaust Clamp

• Restore a perfect, leak-free seal
• Over time, exhaust clamps can deform, corrode, or lose their clamping strength. Replacing the clamp ensures a secure joint between muffler sections, preventing exhaust leaks, restoring proper back pressure, and maintaining optimal engine performance.
• Eliminate rattles and vibration noise
• Worn or loose clamps are a common cause of rattles, buzzing, or vibration noises from the rear underside of 997 and 991 models. Installing a new clamp is often one of the quickest and most cost-effective ways to eliminate these irritating sounds.
• Factory specifications fitment for performance models

Common Issues and Failure Modes

• Corrosion and rust
• Exhaust clamps and fasteners are exposed to heat, moisture, and road salt. Over time, this can lead to corrosion or seizure, reducing clamping force and risking exhaust leaks.
• Clamp fatigue or deformation
• Repeated heat cycles and vibration can cause the clamp sleeve or bolt to distort, leading to a loose connection and exhaust blow-by.
• Incorrect fitment or short sleeves
• Noise from over-tightening
• Applying excessive clamping force can alter vibration characteristics and introduce new noises. Always follow correct installation torque and alignment procedures.

Mounting kit for rear exhaust.
The OE Match Rear Exhaust Mounting Kit is a complete hardware set designed to replace worn or missing mounting components for the rear exhaust system on the Porsche 997. It includes the essential rubber hangers, brackets, bolts, and insulators needed to restore proper exhaust support and alignment.

Fits:
Porsche 997 3.6L-3.8L 2005-08 (not Turbo/GT2)

Kit included:
2x Pipe Connector, 55x58.5x75mm, stainless steel
2x Bolt, M8x1.25x140mm
2x Bolt, M8x1.25x70mm
4x Lock nut, M8x1.25

This product is a comprehensive OE Match rear exhaust mounting kit for the Porsche 997 family. Over time, exhaust mounting rubbers, brackets, and associated fixings can deteriorate due to heat cycling, vibration, and exposure to corrosive elements. This kit brings together all the normal wear components in one package, allowing a complete refresh of the rear exhaust support hardware.

Each piece in the kit has been selected or engineered to match the dimensions, materials, and load-bearing characteristics of the factory parts, ensuring correct exhaust position and reduced risk of sagging, rattling, or detachment.

Over time, rear exhaust mounting components can:
• Harden, crack, or split due to age and heat
•  Corrode and weaken under road salt and moisture exposure
•  Stretch or deform, allowing excessive exhaust movement
•  Loosen, causing rattle, vibration, or exhaust contact with bodywork

Failing mounts can lead to:
•  Exhaust system sagging
•  Unwanted noises
•  Metal fatigue or cracking
•  Reduced ground clearance

Installing a complete OE Match rear exhaust mounting kit restores proper support, improves NVH (noise, vibration, harshness), and helps prolong the life of the exhaust system.

When to replace.  Install this kit when:
•  You notice exhaust sagging at the rear
•  There’s excessive vibration or noise from the exhaust area
•  Exhaust hangers show visible wear, cracking, or separation
•  You are replacing or removing the rear exhaust system
•  You’re performing a comprehensive underbody service
