Fabspeed Cat By-Pass Pipes. Porsche 997.2 Turbo / Turbo S 2010-12 ❭ FSPOR9972TCB
- Porsche 997 MKII Turbo 2010-13
The Fabspeed Cat Bypass Pipes are high-performance straight-through exhaust pipes developed for the Porsche 997.2 Turbo and Turbo S from 2010–2012.
Fits:
- Porsche 997 MKII Turbo / Turbo S 2010-12
Designed specifically for track and off-road applications, these pipes replace the restrictive factory catalytic converters with a freer-flowing exhaust path. Removing the catalyst section reduces exhaust restriction after the turbochargers, allowing exhaust gases to exit more freely while producing a significantly louder and more aggressive exhaust note.
What This Product Does:
The factory exhaust system uses catalytic converters to treat exhaust gases before they leave the vehicle.
Although catalytic converters perform an important emissions-control function, they also create some resistance to exhaust flow.
The Fabspeed Cat Bypass Pipes remove this catalyst section entirely and replace it with straight-through stainless-steel tubing.
Their purpose is to provide:
- Increased exhaust flow
- Reduced exhaust restriction
- Improved throttle response
- Increased performance potential
- Reduced exhaust-system weight
- Increased exhaust volume
- More noticeable turbocharger spool
- More aggressive flat-six exhaust sound
These characteristics make the pipes primarily suited to track and competition vehicles where maximum exhaust flow is prioritised over road-going emissions compliance.
When Might Cat By-Pass Pipes Be Considered:
These pipes are not conventional replacement catalytic converters.
They are a track-focused performance modification intended to remove the catalytic-converter section completely.
They may be considered when:
- Building a closed-course track vehicle
- Maximum exhaust flow is desired
- A more aggressive exhaust note is wanted
- Increased turbo spool sound is desired
- Reduced exhaust-system weight is important
- The vehicle is being modified for competition use
- Other compatible performance upgrades are being installed
For a road-going vehicle, catalytic converters should not simply be removed as a replacement for failed components.
Why Replacement Matters:
A damaged or internally collapsed catalytic converter can restrict exhaust flow.
This can lead to:
- Reduced engine performance
- Poor throttle response
- Increased exhaust backpressure
- Excessive exhaust temperatures
- Engine-management faults
- Poor acceleration
On a road-going vehicle, the correct solution is normally to diagnose the cause and replace a failed catalytic converter with an appropriate emissions-compliant component.
For a dedicated track or off-road vehicle, Fabspeed Cat Bypass Pipes provide an alternative performance configuration that removes the catalysts and maximises exhaust flow.
