Heat Exchanger Mounting Kit 

Ensure a secure and reliable installation of your air-cooled Porsche exhaust system with this OE Match Heat Exchanger Mounting Kit. This complete hardware kit contains the essential mounting components required when installing or replacing heat exchangers.

Porsche 911 1965-1968 2.0L / 912 SWB (F)
Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
Porsche 911 1974-1976 2.7L / 1976 3.0 Carrera

Heat exchangers are exposed to constant heat cycles, moisture, road salt and vibration, making the original mounting hardware highly susceptible to corrosion, seized fasteners and fatigue. Reusing old hardware can make installation difficult and may compromise the security and alignment of the exhaust system.

This OE Match mounting kit provides the correct replacement hardware to ensure your heat exchangers are securely fitted, helping maintain proper exhaust sealing, reduce unwanted movement and support long-term reliability. Whether you're replacing heat exchangers, rebuilding an engine or carrying out a full restoration, installing new mounting hardware is always recommended.

Manufactured to OE Match standards, every component is designed for precise fitment and dependable performance.

What Does the Heat Exchanger Mounting Kit Do?

The mounting kit provides the hardware required to securely fasten the heat exchangers to the engine and exhaust system.

Its primary functions include:

  • Securing the heat exchangers in the correct position.
  • Maintaining proper exhaust alignment.
  • Supporting effective exhaust sealing.
  • Preventing movement caused by vibration.
  • Providing reliable long-term fastening.
  • Simplifying heat exchanger installation.

Using new mounting hardware helps ensure the exhaust system performs correctly while reducing the likelihood of future maintenance issues.

Why Replace Heat Exchanger Mounting Hardware?

Original exhaust hardware is subjected to extreme operating conditions and often deteriorates over time.

Common reasons for replacement include:

  • Corroded nuts and fasteners.
  • Seized or damaged hardware.
  • Fatigued mounting components.
  • Broken or rounded fasteners during removal.
  • Exhaust restoration projects.
  • Engine rebuilds.
  • Heat exchanger replacement.
  • Preventative maintenance.

Replacing the complete mounting hardware during installation helps ensure a secure fit and reduces the risk of future exhaust problems.

Features

  • Designed for Porsche 911 (1963-1976).
  • Complete installation hardware set.
  • Precision manufactured for accurate fitment.
  • High-quality, durable components.
  • Helps ensure secure heat exchanger installation.

Exhaust strap made out of titanium,  Length 510mm
Need 2 per car. Price shown is for each. 

Upgrade your classic Porsche 911 with the Titanium Exhaust Silencer Strap. This strap secures the rear silencer (muffler) to the chassis, helping keep the exhaust system solidly mounted. The titanium version retains the exact fit of the original while offering superior strength, corrosion resistance, and lighter weight — perfect for restoring your 911 or improving long-term reliability.

Fits:
Porsche 911 1965 - 1983

Diagram ref no 20

Made to handle heat, road vibration, and exposure to elements, the titanium strap prevents the muffler from sagging or vibrating excessively. If the original stainless or steel strap is rusted, loose, or damaged, this titanium upgrade will restore secure mounting, reduce noise, and protect other exhaust and chassis components from damage.

Why replacing it matters:
If you leave a worn strap in place: the muffler may drop or become misaligned, leading to vibrations, noise, or even exhaust contacting underbody parts. Over time, this can damage hangers, exhaust joints, or brackets, potentially causing exhaust leaks or more significant repairs.

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.
