The OE Match Rear Exhaust, 2 In 1 Out, Ø70mm Tail Pipe is a premium-quality replacement rear silencer designed to restore the original exhaust performance, sound and appearance of compatible classic Porsche models. Manufactured to OE specifications for fit, flow characteristics and durability, this exhaust features a 2-inlet, 1-outlet configuration with a 70mm polished tailpipe, delivering factory-style performance while maintaining the authentic Porsche exhaust note.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
Constructed from high-quality aluminised steel with precision-welded seams and internal baffles, the silencer is engineered to withstand high exhaust temperatures, vibration, condensation and corrosion. The OE-style internal design ensures optimum exhaust gas flow, effective noise reduction and correct back pressure for reliable engine performance. Precision-manufactured for direct OE-style installation, it offers a straightforward replacement for worn or damaged original rear silencers.
What This Product Does:
- Channels exhaust gases safely from the engine.
- Reduces exhaust noise through an OE-style silencer design.
- Maintains correct exhaust back pressure for efficient engine operation.
- Supports smooth and unrestricted exhaust gas flow.
- Features a 2-inlet, 1-outlet configuration with a Ø70mm tailpipe.
- Restores the factory appearance and exhaust note.
- Helps optimise engine performance and drivability.
- Forms an essential part of the vehicle's exhaust system.
Symptoms Of Wear Or Failure:
- Excessively loud exhaust noise.
- Blowing or leaking exhaust gases.
- Visible rust or corrosion on the silencer.
- Holes or cracks in the exhaust casing.
- Rattling caused by loose internal baffles.
- Reduced engine performance due to exhaust restriction.
- Exhaust fumes entering beneath the vehicle.
- Loose or damaged exhaust mounting points.
- Increased vibration from the exhaust system.
- MOT or vehicle inspection failure due to exhaust leaks or excessive emissions.
Why Replacement Matters:
- The rear exhaust silencer operates under extreme temperatures and is continually exposed to moisture, road salt, vibration and condensation. Over time, internal corrosion, external rust and metal fatigue can weaken the silencer, reducing its ability to control exhaust flow and noise effectively.
- A damaged rear exhaust can cause exhaust leaks, increased noise levels, reduced engine efficiency and unwanted vibration. In severe cases, leaking exhaust gases may pose a safety risk while placing additional strain on other exhaust system components.
- Replacing a worn or damaged rear exhaust restores correct exhaust flow, factory sound levels and reliable engine performance. The OE Match replacement provides factory-style fitment, durable construction and long-lasting corrosion resistance, ensuring dependable performance, improved refinement and the authentic driving experience expected from your Porsche.

Standard Silencers
OEMatch 2 IN / 1 OUT Standard Silencers — Flow, Response, Refinement
Many owners search for genuine or OEM silencers; OEMatch offers practical alternatives for Porsche exhaust systems. These 2 in / 1 out standard silencers are supplied as replacement items for compatible exhaust layouts and are selected to support application-specific needs for Porsche models.
Available Types
- Standard 2 in / 1 out replacement silencer for 2 in / 1 out exhaust layouts fitted to Porsche models
Understanding OEMatch 2 IN / 1 OUT Standard Silencers
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original 2 in / 1 out standard silencers. OE (Original Equipment) refers to parts matching original specifications for the 2 in / 1 out standard silencers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM 2 in / 1 out standard silencers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch provides a wide selection of Porsche components, including exhaust hardware and replacement silencers, catalogued to support repair and restoration across many model years.
Benefits Include
- Direct-fit replacements engineered to match original-spec dimensions and tolerances
- Help preserve exhaust routing and back-pressure characteristics where specifying a like-for-like silencer is required
- Retain original mounting points and connection types to align with existing hangers and sensor locations
Why 2 IN / 1 OUT Standard Silencers Wear and Fail
- Corrosion and perforation from moisture, road salts and exhaust condensate
- Internal packing or resonator material degradation causing noise or restriction changes
- Physical damage from impacts, failed mounts or exhaust system misalignment
The Importance of Replacing with OEMatch 2 IN / 1 OUT Standard Silencers
A correctly functioning silencer maintains exhaust integrity, helps control noise characteristics and reduces the risk of exhaust leaks that can affect emissions or introduce fumes to the cabin. Replacing a degraded silencer with a part selected for Porsche models supports continued operation and helps prevent secondary damage to adjacent components such as hangers, pipes and sensors.
Advantages
- Cost-effective alternative to hard-to-source items while matching original-spec dimensions for consistent fit
- Made to fit original mounting points and clearances to simplify installation
- Selected for Porsche models and documented to aid correct identification and replacement
