Kit Includes:
2x Restraing strap
4x Clamp, M19202-02, stainless steel
2x Bolt, M8x1.25x50mm
4x Bolt, M8x1.25x65mm
4x Lock Nut, M8x1.25mm
8x Washer, 16.8x8.5x3mm
Supplied without sealing rings, this mounting kit is ideal when existing sealing rings are serviceable or are being purchased separately. Manufactured from high-strength, corrosion-resistant materials, the included hardware is engineered to withstand extreme exhaust temperatures, vibration, moisture and road salt, ensuring long-lasting reliability and dependable clamping performance.
What This Product Does:
- Provides the essential hardware required to install the rear exhaust assembly.
- Secures the rear silencer safely and correctly.
- Maintains proper exhaust alignment.
- Helps create stable, leak-free exhaust connections when used with the appropriate sealing rings.
- Replaces worn, corroded or seized original mounting hardware.
- Reduces exhaust movement and vibration.
- Supports professional-quality exhaust installation.
- Forms an essential part of rear exhaust servicing and replacement.
Symptoms Of Wear Or Failure:
- Loose rear exhaust components.
- Rattling or knocking noises from the exhaust system.
- Corroded or seized nuts, bolts or clamps.
- Broken or missing mounting hardware.
- Exhaust movement during driving.
- Poor exhaust alignment.
- Difficulty securing replacement exhaust components.
- Premature wear of exhaust mounts or joints.
- Increased exhaust vibration.
- Visible corrosion or deterioration of fastening components.
Why Replacement Matters:
- Rear exhaust mounting hardware is constantly exposed to extreme temperatures, moisture, road debris and continuous vibration. Over time, these harsh conditions can cause fasteners to corrode, seize or lose their clamping force, reducing the security of the exhaust installation.
- Reusing old hardware during exhaust replacement can result in loose connections, excessive vibration and poor alignment, potentially shortening the life of new exhaust components. Worn fixings may also make future servicing more difficult and increase the risk of broken studs or seized fasteners.
- Replacing the mounting hardware whenever the rear exhaust is removed or replaced helps ensure secure installation and dependable long-term performance. The OE Match Mounting Kit provides factory-style fitment, corrosion-resistant construction and durable fastening performance, making it the ideal solution for Porsche exhaust repairs and maintenance.
- Please note: This kit is supplied without sealing rings. Any required exhaust sealing rings should be purchased separately if replacement is necessary.

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

With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.
Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.
Now also includes our SR065D drill guide.
