Information
Exhaust muffler strap
This OE Match exhaust muffler strap is a direct replacement for the original Porsche component used in the 993 exhaust system. It is designed to wrap around and support the rear silencer, securing it firmly to the vehicle’s mounting brackets. It fits either left or right side silencers and is commonly used in pairs, with one strap per muffler. Additional hardware (bolt) may be required: 90006736201
Sold individually
Fits:
Porsche 993 C2 / C4 1994 - 1998
* not turbo models
Diagram Ref No 1
The muffler strap holds the exhaust silencer securely in place, preventing movement or sagging. It helps maintain proper exhaust alignment while reducing vibration and stress on exhaust joints and mounting points.
Function
• Secures the exhaust muffler to the vehicle chassis
• Maintains correct exhaust alignment and positioning
• Absorbs and reduces vibration from exhaust system
• Prevents excessive movement or sagging of the silencer
• Supports long-term durability of exhaust components
Exhaust straps are exposed to constant heat cycles, moisture, and road debris, which can lead to corrosion or fatigue over time. A worn or broken strap can cause the muffler to loosen or misalign, leading to noise, vibration, or damage to the exhaust system. Replacing it ensures secure mounting and preserves exhaust system integrity.
When to replace
• Visible corrosion, cracking, or fatigue
• Loose or sagging exhaust muffler
• Increased vibration or rattling noise
• During exhaust repair or replacement
• Missing or damaged mounting strap

Information
Clamp for mounting exhaust to heat exchanger.
It is manufactured to replicate the original Porsche specification, offering correct diameter, mounting geometry, material durability and secure fastenings.
Sold each, 2 required per vehicle.
Fits:
Porsche 356 A/B/C 1.6L 01/1955 - 12/1965
Porsche 912 1.6L 01/1965 - 02/1970
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.
