Exhaust clamp for catalyst pipe.
The catalyst pipe exhaust clamp’s role is to securely join the catalytic converter to the adjoining exhaust pipe, forming a strong, sealed mechanical connection. It compresses around the overlapping exhaust tubing to prevent exhaust gas leaks, help maintain correct exhaust flow, and keep the exhaust system components properly aligned under all driving conditions.

•  Application: Exhaust clamp for catalytic converter pipe - secures the joint between the catalytic converter outlet and the downstream exhaust pipe. Designed to match OEM fit and function on the specified 996 Porsche models.

A high-quality exhaust clamp designed to replicate the original Porsche factory clamp used to secure the catalyst (catalytic converter) pipe on Porsche 996 Carrera and GT3 models. This clamp is manufactured to match the exact diameter, strength, and fit of the Porsche original, ensuring a reliable, leak-free connection in the exhaust system.

Installed at the catalyst pipe to exhaust pipe junction, this clamp:
• Provides a tight seal to prevent exhaust leaks
• Holds exhaust sections firmly together during vibration and thermal cycling
• Helps maintain correct exhaust back pressure and performance
• Resists corrosion and heat for long-term durability

Exhaust clamps operate in a harsh environment exposed to high heat, constant vibration, and corrosion, which over time can cause them to rust, weaken, lose clamping force, and allow exhaust leaks. A worn or loose clamp at the catalyst pipe joint may result in unwanted exhaust noise, reduced performance, or potential emissions issues. Replacing the clamp restores a secure, leak-free connection, ensures correct exhaust back-pressure, and helps extend the life of surrounding exhaust components.

Exhaust clamp for tail pipe.
The exhaust tailpipe clamp secure the tailpipe section to the rear silencer on Porsche 996 models. It reproduces the factory clamp’s diameter, shape and clamping force, ensuring a precise fit around the joint and a clean, original look at the rear of the car.
Sold each, 2 required per vehicle.

Fits:
Porsche 996 1998 - 2005 (not Turbo)

Diagram ref no 22

Fitment & Application Summary:
• Used on Porsche 996 models to clamp the tailpipe sections to the rear silencers (mufflers)
• Suitable for OE exhaust systems and OE-style aftermarket tailpipes that use the original clamp style and diameter.
• Typically one clamp is required per tailpipe joint.

This clamp secures the exhaust tailpipes firmly to the rear silencers and helps seal the joint to minimise exhaust gas leakage at the connection point. It also keeps the tailpipes correctly positioned within the rear bumper cut-outs, preserving both proper clearance and the factory appearance.

Old exhaust clamps can rust, seize, or lose clamping force. When that happens:
•  Tailpipes may sit crooked or sag in the bumper cut-outs.
•  Small exhaust leaks can develop at the clamp joint.
•  The system may begin to rattle or move excessively over bumps.
Replacing a corroded or weakened clamp with a fresh clamp restores solid retention, proper visual alignment and a neat, factory-correct finish at the rear of the car.

You should consider replacing this clamp if:
• The existing clamp is rusted, cracked or deformed.
• Tailpipes feel loose or can be twisted by hand.
• You hear rattles or metallic noises from the rear exhaust area.
• You are fitting new silencers or tailpipes and want fresh hardware.
•  A visual inspection shows heavy corrosion or loss of thread/clamping integrity.

stomski

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.

About Brackets / Clamps / Straps

Exhaust Mounting Brackets, Straps & Clamps – Secure, Silent & Strong

A Porsche exhaust system relies on more than just pipes and silencers — it’s held together by a network of mounting brackets, straps, and clamps that keep everything securely in place. These essential components absorb vibration, maintain correct alignment, and prevent stress or damage to exhaust pipes and mufflers.

At Design911, we stock a full range of exhaust mounting hardware, including brackets, hangers, straps, clamps, gaskets, and fasteners, all designed for long-lasting durability and a perfect fit. Built from high-strength stainless steel and corrosion-resistant materials, these components ensure your exhaust system remains properly supported and free from unwanted noise or movement.

Whether you’re performing a full exhaust replacement or a minor repair, replacing worn or rusted mounting hardware restores proper fitment and protects your Porsche’s exhaust from damage caused by vibration or misalignment.

What Do Exhaust Mounting Brackets, Straps & Clamps Do?

These small but vital parts provide the backbone for your exhaust system’s stability and integrity.

Core Functions:

  • Secure the exhaust system to the vehicle chassis.
  • Maintain correct alignment to prevent strain on joints and flanges.
  • Absorb engine vibration to reduce stress and cracking.
  • Ensure leak-free connections between pipes and silencers.
  • Prevent rattling and unwanted noise during acceleration and cornering.

Without properly functioning brackets and clamps, your exhaust can sag, vibrate, or even detach — risking costly damage and performance loss.

Why Do Exhaust Mounts and Clamps Fail?

Constant heat, vibration, and exposure to the elements make exhaust mounting components prone to wear over time.

Common Causes of Failure Include:

  • Corrosion or rust from road salt and moisture.
  • Metal fatigue caused by heat cycling and vibration.
  • Cracked or stretched straps from repeated stress.
  • Loose or broken clamps leading to exhaust leaks.
  • Rubber mount deterioration resulting in noise or exhaust movement.

Failure of these components can lead to exhaust misalignment, rattling, leaks, or premature pipe damage — issues that worsen quickly if ignored.

Why Replace Components?

Replacing worn or damaged exhaust mounting hardware ensures your Porsche’s exhaust system remains stable, quiet, and free-flowing.

Key Benefits:

  • Restores exhaust alignment and fitment.
  • Prevents damage to mufflers, pipes, and joints.
  • Eliminates rattling, vibration, and leaks.
  • Durable stainless steel and heat-resistant construction.
  • Direct-fit compatibility for all Porsche models, classic and modern.
  • Ideal for maintenance, restoration, or performance upgrades.

A secure exhaust system not only improves comfort and performance but also extends the life of other components — ensuring your Porsche remains refined and reliable.

Highlights:

  • High-quality exhaust brackets, clamps, and mounting straps.
  • Precision-engineered for Porsche fitment and durability.
  • Prevents vibration, movement, and exhaust leaks.
  • Made from corrosion-resistant stainless steel.
  • Perfect for restorations or exhaust maintenance.
  • Ensures long-term stability and quiet operation.
