Product Information
Exhaust strap made out of titanium,  Length 510mm
SET OF 2 straps, with bolts

Upgrade your classic Porsche 911 with the Titanium Exhaust Silencer Straps. These straps secure the rear silencers (mufflers) to the chassis, keeping the exhaust system firmly mounted in place. Designed with the same precise fit as the original parts, the titanium straps deliver superior strength, excellent corrosion resistance, and reduced weight. Perfect for restoration projects or enhancing long-term reliability of your 911, this set ensures both silencers are supported with lasting durability.

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.
