The catalyst pipe exhaust clamp’s role is to securely join the catalytic converter to the adjoining exhaust pipe, forming a strong, sealed mechanical connection. It compresses around the overlapping exhaust tubing to prevent exhaust gas leaks, help maintain correct exhaust flow, and keep the exhaust system components properly aligned under all driving conditions.
Sold each.

• Application: Exhaust clamp for catalytic converter pipe - secures the joint between the catalytic converter outlet and the downstream exhaust pipe. Designed to match OEM fit and function on the specified 996 Porsche models.
A high-quality exhaust clamp designed to replicate the original Porsche factory clamp used to secure the catalyst (catalytic converter) pipe on Porsche 996 Carrera and GT3 models. This clamp is manufactured to match the exact diameter, strength, and fit of the Porsche original, ensuring a reliable, leak-free connection in the exhaust system.
Installed at the catalyst pipe to exhaust pipe junction, this clamp:
• Provides a tight seal to prevent exhaust leaks
• Holds exhaust sections firmly together during vibration and thermal cycling
• Helps maintain correct exhaust back pressure and performance
• Resists corrosion and heat for long-term durability
Exhaust clamps operate in a harsh environment exposed to high heat, constant vibration, and corrosion, which over time can cause them to rust, weaken, lose clamping force, and allow exhaust leaks. A worn or loose clamp at the catalyst pipe joint may result in unwanted exhaust noise, reduced performance, or potential emissions issues. Replacing the clamp restores a secure, leak-free connection, ensures correct exhaust back-pressure, and helps extend the life of surrounding exhaust components.

The exhaust tailpipe clamp secure the tailpipe section to the rear silencer on Porsche 996 models. It reproduces the factory clamp’s diameter, shape and clamping force, ensuring a precise fit around the joint and a clean, original look at the rear of the car.
Sold each, 2 required per vehicle.
Fits:
Porsche 996 1998 - 2005 (not Turbo)
Diagram ref no 22
Fitment & Application Summary:
• Used on Porsche 996 models to clamp the tailpipe sections to the rear silencers (mufflers)
• Suitable for OE exhaust systems and OE-style aftermarket tailpipes that use the original clamp style and diameter.
• Typically one clamp is required per tailpipe joint.
This clamp secures the exhaust tailpipes firmly to the rear silencers and helps seal the joint to minimise exhaust gas leakage at the connection point. It also keeps the tailpipes correctly positioned within the rear bumper cut-outs, preserving both proper clearance and the factory appearance.
Old exhaust clamps can rust, seize, or lose clamping force. When that happens:
• Tailpipes may sit crooked or sag in the bumper cut-outs.
• Small exhaust leaks can develop at the clamp joint.
• The system may begin to rattle or move excessively over bumps.
Replacing a corroded or weakened clamp with a fresh clamp restores solid retention, proper visual alignment and a neat, factory-correct finish at the rear of the car.
You should consider replacing this clamp if:
• The existing clamp is rusted, cracked or deformed.
• Tailpipes feel loose or can be twisted by hand.
• You hear rattles or metallic noises from the rear exhaust area.
• You are fitting new silencers or tailpipes and want fresh hardware.
• A visual inspection shows heavy corrosion or loss of thread/clamping integrity.

OEMatch Brackets / Clamps / Straps — Fit, Function, Confidence
Small mounting parts that secure and support Porsche exhaust systems, engineered to control alignment, absorb vibration and reduce unwanted noise. Correct fixing points and appropriate materials help preserve joint seals, prevent sagging and limit transmission of engine and road vibration into the cabin or bodywork.
Available Types
- Exhaust mounting brackets and hangers for chassis attachment
- Stainless-steel straps and clamp assemblies for pipe and silencer joints
- Rubber-insulated hangers, mounting bolts and dedicated fasteners
Understanding OEMatch Brackets / Clamps / Straps
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original brackets, clamps and straps.
OE (Original Equipment) refers to parts matching original specifications for the brackets, clamps and straps and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM brackets, clamps and straps engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a broad range of Porsche-fitment mounting hardware and related fasteners, drawing on a catalogue that documents thousands of part numbers and cross-references. The selection covers common exhaust hangers, dedicated straps and clamp sizes used across classic and modern Porsche models, with ongoing development to extend coverage.
Benefits Include
- Restores correct exhaust alignment to protect joints and flanges
- Reduces rattles and vibration transmitted to the body
- Corrosion-resistant finishes extend service life in exposed locations
Why Brackets / Clamps / Straps Wear and Fail
- Corrosion from road salt and moisture leading to metal loss and weakening
- Metal fatigue and heat cycling causing cracks, deformation or stretched straps
- Deterioration of rubber mounts and isolators that lose damping properties
The Importance of Replacing with OEMatch Brackets / Clamps / Straps
Replacing worn or damaged mounting hardware keeps a Porsche exhaust correctly supported and aligned, preventing additional stress on pipes, joints and silencers. Correctly chosen brackets and clamps reduce the risk of leaks, limit noise and vibration, and make subsequent maintenance or repairs simpler and less intrusive. For restoration or routine maintenance, renewed mounting parts help preserve the overall refinement expected from Porsche models.
Advantages
- Direct-fit designs selected for Porsche applications to match original mounting points and clearances
- Materials and finishes chosen to resist heat and corrosion in exhaust environments
- Wide choice of shapes and fixings to suit restoration and repair needs
