Exhaust bolt repair kit for Boxster / 996 / 997 Carrera & Cayman Gen1 1997- 2009 (Not GT3, GT2 or TT engines)

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.

Exhaust Rear Muffler Retainer Plate. 

The OE MATCH Exhaust Rear Muffler Retainer Plate is an OE-style replacement exhaust mounting component designed for Porsche 986 Boxster models from 1998 to 2004. Designed to match the original equipment application, this retainer plate helps secure the rear exhaust muffler mounting assembly, providing stable support and helping maintain correct exhaust positioning.

Fits:

• Porsche 986 Boxster 1998-04

Diagram Ref No 21

The retainer plate forms part of the exhaust mounting system, working alongside the associated brackets and fixing hardware to help keep the rear muffler securely attached during normal driving conditions.

Exposed to high temperatures, road moisture, corrosion and continuous vibration, original exhaust mounting components can deteriorate over time. The OE MATCH replacement provides a practical solution for repairing worn, damaged or corroded mounting hardware.

Ideal for routine exhaust maintenance, rear muffler replacement and restoration projects, this component helps maintain the structural security and reliability of the Porsche Boxster exhaust system.

What This Product Does:
The exhaust rear muffler retainer plate forms part of the mounting arrangement that secures and supports the rear exhaust muffler. It helps retain the associated fixing components and maintain the correct position of the exhaust assembly.

Its key functions include:

• Secure Muffler Mounting: Helps secure the rear exhaust muffler within its designated mounting assembly.
• Exhaust Stability: Helps maintain correct rear muffler positioning and reduces unwanted movement.
• Vibration Control: Contributes to a secure mounting arrangement, helping minimise excessive exhaust movement and rattling.
• Mounting Support: Works with the associated brackets, nuts and fixings to maintain a reliable mechanical connection.
• Exhaust Alignment: Helps retain the intended position of the rear muffler in relation to surrounding components.
• Component Protection: Helps reduce excessive stress on adjacent exhaust mounting hardware caused by loose or insecure connections.
• OE-Style Fitment: Provides a replacement for the original retainer plate without requiring modification to the specified mounting arrangement.

Symptoms Of Wear Or Failure:
Over time, exposure to exhaust heat, road salt, moisture and vibration can cause the rear muffler retainer plate and associated mounting hardware to deteriorate.

Common signs include:

• Excessive Exhaust Rattling: A loose or damaged retainer plate may allow movement within the rear muffler mounting assembly, resulting in rattling or metallic noises.
• Visible Rust or Corrosion: Prolonged exposure to moisture and road salt can cause corrosion, potentially weakening the mounting component.
• Loose Rear Muffler: Worn or damaged mounting hardware may allow the exhaust muffler to move more than intended.
• Increased Vibration: A weakened mounting connection can contribute to vibration or knocking noises, particularly during acceleration or when driving over uneven surfaces.
• Damaged or Deformed Plate: Cracks, bending or distortion can affect the retainer plate's ability to maintain a secure mounting connection.
• Missing or Loose Fixings: Corroded, damaged or missing retaining nuts can reduce the effectiveness of the mounting assembly.
• Incorrect Exhaust Alignment: A compromised mounting arrangement may allow the rear muffler or exhaust tailpipe to sit out of its intended position.
• Metallic Knocking Sounds: Excessive movement may cause the exhaust assembly to contact nearby mounting hardware or surrounding components.
• Difficulty Securing the Muffler: During exhaust repairs, a heavily corroded or damaged retainer plate may prevent the mounting hardware from tightening correctly.

Why Replacement Matters:

• Replacing a worn or damaged exhaust rear muffler retainer plate is an important part of maintaining the security, stability and reliability of your Porsche Boxster's exhaust system.
• The rear muffler is subjected to continuous vibration, engine movement and temperature changes during normal operation. A damaged or weakened mounting component can allow excessive movement within the exhaust assembly, leading to rattling, poor alignment and additional stress on nearby brackets and fixings.
• A correctly fitted replacement retainer plate helps restore a secure mechanical connection, maintaining proper rear muffler positioning and reducing unwanted movement.
• Excessive exhaust movement can also place additional strain on connecting pipes, exhaust joints and mounting brackets. Replacing deteriorated mounting components can help prevent further damage and reduce the likelihood of more extensive exhaust system repairs.
• Corrosion is another common concern, particularly on vehicles regularly exposed to wet conditions and road salt. Inspecting and replacing heavily corroded retainers during exhaust maintenance helps maintain the integrity of the mounting system.
• For Porsche Boxster owners undertaking rear muffler repairs, exhaust upgrades or restoration work, replacing damaged mounting hardware is an effective way to ensure the exhaust assembly is correctly supported.
• The OE MATCH Exhaust Rear Muffler Retainer Plate provides a practical OE-style replacement solution, helping restore secure exhaust mounting, reduce unwanted vibration and maintain reliable exhaust system operation.

Exhaust sleeve catalytic converter to U-Bend
Genuine Porsche exhaust clamp - also called a clamping sleeve - It is used where the catalytic converter connects to the next section of exhaust (U-bend/silencer pipe) on Porsche 986 Boxster models.
Sold as: Single clamp (two may be required per complete joint).

Fits:
Porsche 986 Boxster 1997 - 2004

Diagram ref no 15

The exhaust clamp helps secure and seal the exhaust connection between the catalytic converter and adjoining exhaust pipe sections. Under normal operation, exhaust components heat up, cool down, and experience vibration; this clamp maintains a tight mechanical joint, preventing exhaust leaks, excessive movement, and noise. Genuine Porsche clamps are engineered with durable materials that withstand heat, corrosion, and vibration as intended by the factory design.

Function:
•  Secures exhaust junctions: Holds exhaust piping tightly together
•  Prevents exhaust leaks: Maintains a sealed joint at critical interfaces
•  Resists corrosive conditions: Designed for high-temperature exposure
•  Ensures proper exhaust alignment: Reduces noise, rattles, and stress on mounts

As part of the exhaust system hardware, proper clamp integrity helps the entire exhaust assembly function smoothly and reliably across varying conditions.

Exhaust clamps are exposed to extreme temperatures, road salts, and moisture - conditions that accelerate corrosion and fatigue. Over time, original clamps can weaken, rust, or lose clamping force, leading to:
•  Exhaust leaks Increased noise or vibration
•  Poor exhaust alignment
•  Potential damage to adjacent components

Using a Genuine Porsche clamp ensures the joint is restored to factory-spec tightness, maintaining proper exhaust pressure sealing and alignment as originally designed.

When to replace. Replace the exhaust clamp when:
•  You are servicing or refitting the exhaust system
•  The original clamp shows rust, deformation, or breaks
•  You hear exhaust leaks or unusual noise at the catalytic converter junction
•  The clamp no longer holds the pipes firmly in place

Exhaust sleeve catalytic converter to u-bend.
OE Match exhaust clamping sleeve / exhaust clamp designed to secure and join exhaust components in the Porsche Boxster 986 (1997–2004) exhaust system. It functions as a durable connector between the catalytic converter and U-bend / silencer pipes, helping maintain a tight exhaust joint.
Sold as: Single clamp (two may be required per complete joint).

Fits:
Porsche 986 Boxster 1997 - 2004

Diagram ref no 15

The exhaust clamping sleeve secures two sections of the exhaust - typically where the catalytic converter outlet meets the U-bend or silencer pipe. It ensures a firm, vibration-resistant connection that prevents exhaust leakage, reduces noise, and supports proper exhaust routing. A good clamp helps the exhaust stay aligned under heat expansion and road vibration, reducing stress on nearby hangers and components.

Function:
•  Joins exhaust sections securely (catalytic converter to U-bend/silencer)
•  Prevents exhaust leaks by maintaining a tight pipe connection
•  Absorbs movement and heat expansion without loosening
•  Supports proper alignment of the exhaust system under operating loads.

Without a sound clamp, exhaust joints can leak hot gases, which leads to reduced performance, unwanted noise, and possible component wear.

Exhaust clamps live in a high-heat, corrosive environment, and over time the original sleeve can:
•  Corrode or rust, reducing clamp effectiveness
•  Lose clamping force from heat cycling
•  Allow exhaust leaks at pipe connections
•   Cause excess exhaust noise or vibration.

Replacing worn or damaged clamps with OE Match units helps ensure a tight seal, prevents exhaust gas escape, and protects other exhaust components from undue movement or stress.

When to replace.  Replace this exhaust clamp when:
•  You remove or refit the exhaust system (e.g., catalytic converter or silencer)
•  The existing clamp is corroded, bent, or stretched

•  You notice exhaust leaks, noise, or vibration at the joint
•  Replacement or servicing of exhaust components causes fitment issues

Diagram ref no 13

It locks the exhaust joint together at the connecting pipe/U-bend interface, maintaining alignment and helping prevent exhaust leaks, vibration, and movement under heat expansion. A fresh clamp is especially important after exhaust removal, where old clamps often seize or deform and can’t be reused reliably.

Function:
• Provides secure clamping force at the U-tube/connecting pipe joint
•  Helps maintain a tight, leak-resistant seal under heat cycling
•  Supports proper exhaust alignment to reduce rattles and stress on joints

Exhaust clamps live in a harsh environment and commonly rust, seize, and become impossible to loosen without damage. Replacing the clamp during exhaust work helps ensure the joint reseals properly, avoids leaks and rattles, and prevents wasted time fighting corroded hardware.

When to replace:
•  When removing/refitting the U-bend or connecting pipe
•  If the clamp is corroded, seized, stretched, or deformed
•  If you have exhaust blowing/leak noise at the joint
•  If bolts/threads are damaged or won’t torque correctly
