Product Information
Upgrade your Porsche with our Titanium Exhaust Bracket. A premium replacement for the OEM rear muffler support bracket used on 996 and 997 models. Crafted from high-grade titanium, this bracket offers the strength and precision fit you expect, with the bonus of lighter weight and superior corrosion resistance. Fit and forget.

Fits:
Porsche 996 C2 / C4 / C4S 1998-05
Porsche 997 Carrera 2009-08 (Sports exhaust system)

Diagram Ref no. 10

Choosing a titanium version of this bracket offers several key advantages. Titanium is far more resistant to rust, corrosion, and fatigue than mild steel or standard alloys, which means it will last longer even under the intense heat and stress of the exhaust system. It’s also much lighter, helping reduce unsprung weight and contributing to improved exhaust response and overall vehicle balance. Finally, the titanium bracket provides the same precise fit as the original, keeping the muffler securely aligned and supported to prevent rattles, misalignment, or damage.

Product Information
Manufactured in titanium for enhanced strength, reduced weight, and outstanding durability, even in high heat conditions. Originally designed to support the catalytic converter / exhaust assembly on Porsche 996 and 997 Gen 1 models, this titanium version delivers all the reliable fit and function of the original steel bracket, but with superior performance.

Fits:
Porsche 996 C2 / C4 08/2001 - 2004
Porsche 997 C2 / C4 2005 - 2008

Mounted behind the rear bumper under the exhaust, it securely supports the catalytic converter, helping to maintain proper exhaust alignment and absorb vibration without cracking or deforming. If you’re after longevity, performance, or reducing corrosion, this titanium bracket is an excellent upgrade.

You may need to replace the bracket if it shows signs of rust, cracks, bending, or deformation. Other warning signs include rattling or vibration from the exhaust or catalytic converter during acceleration or over bumps, visible misalignment of the exhaust system, or a catalytic converter that hangs too low. Worn hangers or mounts caused by added stress from a weak bracket are also clear indicators. If a damaged bracket is not replaced, the exhaust can sag, shift, or make contact with the underbody, creating damage and unwanted noise. The added strain on other mounts and components can accelerate wear, lead to fractures, or cause heat and vibration damage to nearby parts. Left unchecked, this can result in exhaust leaks, failed emissions tests, or costly repairs to the catalytic converter and exhaust system. You wouldn't do this to your Porsche, would you?

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.
