The Fabspeed Porsche 911 Turbo 930 Wastegate Dump Pipe is a lightweight, motorsport-inspired performance exhaust component designed for classic Porsche 911 Turbo (930) models.
Fits:
Developed by Fabspeed Motorsport, this wastegate discharge pipe replaces the original, heavier factory wastegate muffler with a freer-flowing stainless steel outlet.
Manufactured from premium T304L stainless steel, the Fabspeed Wastegate Dump Pipe is engineered to withstand the high exhaust temperatures, vibration and demanding operating conditions associated with turbocharged engines.
The design takes inspiration from the wastegate exhaust arrangements used on Porsche factory racing cars, providing a more direct route for gases released through the turbocharger's external wastegate.
During turbocharger operation, the wastegate regulates boost pressure by diverting a controlled amount of exhaust gas away from the turbine. The factory wastegate muffler helps reduce the noise produced by this discharge.
The Fabspeed Wastegate Dump Pipe replaces that silenced arrangement with a short, open exhaust outlet, producing a more noticeable and aggressive wastegate sound when the valve opens.
Its direct bolt-on construction is designed to simplify installation on compatible Porsche 930 wastegate assemblies without requiring cutting or welding.
The stainless steel construction also offers improved resistance to corrosion compared with ageing exhaust components that may have suffered from repeated heat cycles and environmental exposure.
This product is particularly suited to Porsche 930 enthusiasts seeking a more authentic motorsport exhaust character and a lightweight alternative to the factory wastegate muffler.
Important: The Wastegate Dump Pipe is a performance sound and exhaust-flow upgrade. It does not replace the wastegate valve, actuator or boost-control mechanism and does not itself increase the engine's specified boost pressure.
The open-discharge design can produce extremely loud exhaust noise when the wastegate operates. It is best suited to competition applications where the resulting noise and emissions configuration are permitted.
What This Product Does:
The Fabspeed Wastegate Dump Pipe provides an exhaust outlet for gases diverted through the turbocharger's external wastegate.
The wastegate is a key part of the Porsche 930 turbocharging system. Its role is to help control turbine speed and boost pressure by regulating the amount of exhaust gas passing through the turbocharger.
When the wastegate opens, some exhaust gas is diverted away from the turbine. The dump pipe carries these gases away from the wastegate outlet.
Its key functions and benefits include:
- Wastegate Exhaust Discharge: Provides an outlet for gases released through the external wastegate.
- Reduced Discharge Restriction: Replaces the factory wastegate muffler with a more direct exhaust path.
- Enhanced Wastegate Sound: Produces a louder, more aggressive exhaust note when the wastegate opens.
- Motorsport-Inspired Character: Recreates the distinctive wastegate discharge sound associated with classic turbocharged competition cars.
- Lightweight Construction: Removes the bulk of the original wastegate muffler arrangement.
- Durable Stainless Steel Design: T304L stainless steel provides resistance to corrosion and high exhaust temperatures.
- Direct Bolt-On Installation: Designed to replace the factory wastegate muffler on compatible vehicles.
- Improved Exhaust Simplicity: Provides a straightforward outlet arrangement without the original silencing chamber.
- Turbocharger System Compatibility: Works with the existing wastegate discharge system without replacing the wastegate itself.
- Distinctive Turbocharged Driving Experience: Makes wastegate operation more audible during high-load and boost conditions.
- Competition Exhaust Styling: Provides a race-inspired exhaust configuration for classic Porsche 930 builds.
Symptoms Of Wear Or Failure:
The Fabspeed Wastegate Dump Pipe is primarily a motorsport performance upgrade rather than a routine maintenance replacement.
However, deterioration of the original wastegate muffler or discharge pipe may make replacement necessary.
Common signs of wear or damage include:
1. Corrosion on the Factory Wastegate Muffler
The original muffler is exposed to high exhaust temperatures, moisture and repeated heating and cooling cycles.
Over time, corrosion can weaken the outer housing, joints or mounting connections.
Advanced rust may eventually cause exhaust leaks or structural failure.
2. Exhaust Leaks Around the Wastegate Outlet
Damaged gaskets, cracked pipework or loose connections may allow exhaust gases to escape before reaching the intended outlet.
Possible symptoms include blowing noises, visible soot deposits and unusual exhaust smells.
3. Rattling from the Wastegate Muffler
Internal corrosion or damage may cause components inside the original muffler to loosen.
This can produce metallic rattling or vibration when the wastegate opens.
4. Cracked or Damaged Discharge Pipe
Repeated thermal expansion, vibration and mechanical stress can cause cracks to develop around exhaust connections.
Visible cracking or exhaust leakage may indicate that repair or replacement is required.
5. Damaged Mounting Flange
Warped, corroded or cracked mounting flanges may prevent the muffler or discharge pipe from sealing correctly.
6. Loose or Corroded Fasteners
Heat exposure and ageing can cause exhaust fasteners to seize, corrode or loosen.
A poor connection may allow unwanted movement or exhaust leakage.
7. Excessive Exhaust Vibration
Loose mounting components or damaged connections can cause the factory wastegate muffler to vibrate against surrounding parts.
8. Visible Impact Damage
Damage caused by road debris, improper lifting or previous repairs may deform the wastegate discharge assembly.
9. Blocked or Restricted Discharge Path
A damaged or obstructed wastegate outlet may interfere with normal exhaust discharge.
Any suspected restriction should be investigated promptly because wastegate flow is important to proper boost-pressure regulation.
10. Unusual Turbocharger or Boost Behaviour
Inconsistent boost pressure, boost spikes or overboost conditions can indicate a problem within the wider wastegate or boost-control system.
However, these symptoms should not automatically be attributed to the wastegate muffler or dump pipe.
They may result from a sticking wastegate valve, damaged diaphragm, incorrect boost spring, faulty pressure hoses or other turbocharging faults.
Why Replacement / Upgrading Matters:
- Maintaining the condition of the wastegate discharge system is important for correct turbocharger operation, exhaust integrity and overall vehicle safety.
- The Porsche 911 Turbo 930 uses a turbocharger to increase engine performance by using exhaust gas energy to compress intake air.
- The external wastegate helps regulate turbocharger boost by diverting some exhaust gas away from the turbine when the required operating conditions are reached.
- The wastegate's discharge system must allow these gases to escape through the intended exhaust route.

Oxygen sensor ports are threaded openings in the exhaust system that normally accommodate a lambda sensor. When the port is not being used, it must be properly sealed. Leaving the opening exposed can allow hot exhaust gases to escape and may permit moisture and contamination to enter the exhaust system.
What This Product Does:
- Seals an unused oxygen or lambda sensor mounting hole.
- Prevents exhaust gases escaping through an unused sensor port.
- Helps maintain the integrity of the exhaust system.
- Protects the threaded sensor opening from dirt and contamination.
- Helps reduce moisture entering through an unused port.
- Allows an exhaust component with an oxygen sensor boss to be used where a sensor is not required.
- Provides a removable solution if an oxygen sensor is required later.
- Replaces a missing, damaged or corroded blanking plug.
- Provides an OE-style solution for compatible exhaust applications.
Symptoms Of Wear Or Failure:
- Exhaust gases leaking around the plug.
- A ticking or blowing noise from the oxygen sensor port.
- Black soot deposits around the plug or threaded opening.
- A strong exhaust smell near the affected area.
- The plug has become loose.
- Visible corrosion or deterioration.
- Damaged or stripped plug threads.
- A plug that can no longer be securely tightened.
- The original blanking plug is missing.
- An oxygen sensor has been removed and the port remains open.
- Heat or exhaust staining around the sensor boss.
Why Replacement Matters:
- An unused oxygen sensor hole should never be left open during normal engine operation. Exhaust gases are extremely hot and can escape through the opening at high velocity, potentially damaging nearby components and creating excessive noise.
- An exhaust leak can also affect the correct operation of the exhaust system. Depending on the location of the unused port and the vehicle's configuration, unwanted air entering the exhaust may also interfere with exhaust-gas measurements or diagnostic testing.
- The threaded sensor boss itself can deteriorate if left exposed. Dirt, moisture and corrosion may damage the threads, making installation of a future oxygen sensor more difficult or requiring repair of the sensor mounting point.
- A loose or damaged plug can produce similar problems. Soot deposits around the port are often an indication that combustion gases are escaping past the sealing surface or threads.

The Fabspeed Porsche 911 Carrera European Pre-Muffler Pipe is a performance exhaust upgrade designed for classic Porsche 911 SC and Carrera models from 1976–1989.
Fits:
- Porsche 911 1976-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC

Based on the European pre-muffler concept, this component replaces the original catalytic converter with a freer-flowing, resonated exhaust section. The result is reduced exhaust restriction, improved throttle response, reduced weight and a stronger air-cooled flat-six exhaust note.
Unlike a simple straight catalyst bypass pipe, the Fabspeed European Pre-Muffler incorporates a straight-through resonator with stainless-steel wool packing. This helps produce a deeper, more refined performance exhaust tone while reducing the harsh rasp often associated with completely straight-piped exhaust systems.
What This Product Does:
The pre-muffler replaces the factory catalytic converter section of the exhaust system.
Instead of forcing exhaust gases through the restrictive catalyst substrate, the Fabspeed pipe provides a freer-flowing route towards the rear muffler.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Reduce backpressure
- Improve throttle response
- Increase horsepower and torque potential
- Reduce exhaust-system weight
- Increase exhaust volume
- Enhance the classic air-cooled flat-six sound
Because the original catalytic converter is removed, the component no longer provides the emissions-treatment function of the factory catalyst.
Resonated European Design:
- Rather than using a completely empty straight pipe, Fabspeed incorporates a straight-through resonator.
- The resonator allows exhaust gases to travel through the system with minimal restriction while controlling some of the undesirable frequencies produced by an unrestricted exhaust.
- Its stainless-steel wool packing helps create a deeper, more purposeful exhaust character without the excessive rasp commonly associated with a basic straight catalyst-delete pipe.
Performance Benefits:
Fabspeed states that the European Pre-Muffler provides 16+ wheel horsepower and 15+ ft-lb of torque, together with significantly improved throttle response.
During Fabspeed DynoJet testing, peak curve gains of up to 21 WHP and 17 ft-lb at approximately 4,500 rpm were recorded, with maximum power increases of approximately 16 WHP and 16 ft-lb.
These are manufacturer-reported figures from a specific test vehicle and should not be considered guaranteed results for every Porsche 911.
Actual performance can vary depending on:
- Engine condition
- Engine specification
- Existing exhaust system
- Intake modifications
- Fuel system condition
- Ignition condition
- Engine tuning
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
This product is primarily a performance exhaust modification, rather than a routine service replacement.
The original catalyst does not need to have failed before the Fabspeed pre-muffler can be installed on a vehicle intended for appropriate competition or off-road use.
Reasons for upgrading include:
- Reduced exhaust restriction
- Improved exhaust flow
- Increased horsepower potential
- Increased torque potential
- Sharper throttle response
- Approx. 8 lb weight reduction
- Stronger air-cooled flat-six sound
- Resonated design to control rasp
- T304L stainless-steel construction
- Straightforward bolt-on installation
