Brackets / Clamps / Straps
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.

Position on Vehicle: Connects the muffler (rear silencer) to the heater/exchanger unit of the exhaust system.
Applications: Ideal when the original clamp is corroded, broken, allowing exhaust leak at the joint, or if restoration demands correct specification hardware.
A sound exhaust system clamp ensures the crucial connection between muffler and heater-exchanger remains sealed and tethered. If this joint fails or the clamp is weakened, you may experience: noisy exhaust leaks, lower back-pressure, potential heater/exchanger corrosion or stress, increased exhaust heat intrusion under the car. Installing a correct clamp restores system integrity and protects the exhaust components.
When and why to replace:
• Visible rust, cracking or breaking of the original clamp.
• Audible exhaust leak or heat-exchange joint sound.
• During full exhaust removal or restoration when the heater/exchanger is exposed.
• When restoring a classic Porsche to correct specification with original-style parts.

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.

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.
