Titanium Exhaust Sleeve – Catalytic Converter to Rear Silencer Grade 5 Titanium (Ti-6Al-4V) Porsche 996 / 997 / 991 

Replaces Porsche Part Number: 99711152000 

This Grade 5 titanium exhaust sleeve connects the catalytic converter to the rear silencer and represents a significant upgrade over the original Porsche steel sleeve and conventional aftermarket alternatives. Manufactured from aerospace-grade Grade 5 titanium (Ti-6Al-4V), this Rohler exhaust sleeve delivers exceptional strength, corrosion resistance, and weight reduction, making it the ideal long-term solution for performance-focused and enthusiast-owned Porsches.

Precision-engineered for accurate fitment across multiple Porsche generations, this upgraded sleeve fits 996, 997, and select 991 Carrera models, offering broader compatibility than many aftermarket options while retaining true bolt-on installation.

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.
