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.

The Ninemeister repair flange is a high-quality replacement solution designed specifically to restore your Porsche’s exhaust integrity.
Key Features
- Direct
Repair Solution – allows you to remove the corroded flange and re-weld
this precision-machined replacement in place.
- Durable
Construction – built to withstand the extreme heat and corrosive
conditions of Porsche exhaust systems.
- Restores
Exhaust Sealing – eliminates leaks, restores back pressure, and
ensures smooth engine performance.
- Cost-Effective
Repair – no need to replace the entire catalytic converter when only
the flange is damaged.
- Tailored Fitment – engineered to match Porsche specifications for proper alignment and fit.
Why Replace a Corroded Converter Flange?
- Eliminate
Exhaust Leaks – prevent harmful gases from escaping and affecting
cabin safety.
- Restore
Performance – exhaust leaks reduce back pressure, causing poor
throttle response and reduced efficiency.
- Prevent
Further Damage – corrosion at the flange can spread, leading to costly
catalytic converter or exhaust system replacements.

Fitting titanium nuts and bolts to a Porsche exhaust system instead of the standard steel ones (which are prone to rusting) offers several clear advantages, especially in a high-heat, corrosive environment like the exhaust area.

Advantages of Titanium over Steel for Exhaust Fasteners
• Corrosion Resistance, Titanium does not rust like steel, even when exposed to road salt, water, or exhaust gases.
• This makes it ideal for exhaust systems, where steel fixings often seize or corrode, making future removal difficult.
• Lightweight. Titanium is around 40–45% lighter than steel. On a Porsche, reducing unsprung or rear-end weight helps with performance, balance, and handling.
• High Strength-to-Weight Ratio, Titanium fasteners offer excellent tensile strength while being much lighter.
• This allows them to handle exhaust vibrations and thermal expansion without stretching or breaking.
• Heat Resistance, Titanium maintains its strength at much higher temperatures compared to standard steel.
• Exhaust areas can easily see 600–900°C, and titanium is much less likely to weaken under those conditions.
• No Seizing or Galling from Rust, Standard steel exhaust nuts often seize and require cutting or drilling during maintenance.

Front Suspension Wear and Replacement
On the Porsche 993, common failure points in the front suspension include the
control arms, ball joints, tie rods and bellows. As these components wear, you may notice clunking over bumps, loose or vague steering, uneven tire wear, or steering wheel vibration. Because the front suspension system is highly interconnected, wear in one part often accelerates the deterioration of other components.
To address this, we’ve developed a complete wishbone arms, ball joints & tie rods designed to restore handling, performance, and safety. This kit includes new front control arms, ball joints, tie rods and bellows ensuring a comprehensive solution rather than piecemeal repairs.

Why Control Arms Matter
Control arms serve as a critical link between the suspension and the subframe. Their hinged design allows the suspension to articulate as the vehicle absorbs bumps or navigates turns. On vehicles with independent suspension, like the 993, multiple arms and connection points contribute to better ride comfort and stability.
As bushings and joints within a control arm wear out, the suspension can begin to feel loose or unstable. While some designs allow individual components to be serviced, many control arms require complete replacement to restore proper function.
Symptoms of Control Arm Failure
Signs that your control arms may need replacement include:
- Excessive play where the arms connect to the subframe or knuckle
- Clunking or knocking noises from the suspension
- Uneven tire wear
- Difficulty achieving proper wheel alignment
- Steering wheel vibration at highway speeds
- Wandering or pulling sensation through the steering wheel
