- Porsche 997 MKII GT2 RS 2011-13
The Fabspeed Sport Headers are a high-performance replacement for the factory exhaust manifolds on the 2011 Porsche 997.2 GT2 RS.
Fits:
- Porsche 997 MKII GT2 RS 2011-13
Designed to improve the flow of exhaust gases from the cylinder heads to the turbochargers, these headers provide a less restrictive exhaust path intended to improve engine response and turbocharger performance.
The system is manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel and incorporates high-velocity 3-into-1 merge collectors. These CAD-designed collectors bring the exhaust gases from each bank together efficiently before they reach the turbochargers, helping improve exhaust scavenging and minimise unnecessary turbulence.
Fabspeed designed the headers as a direct bolt-on replacement for the factory manifolds, making them suitable both as a performance upgrade and as a replacement for damaged or deteriorated original headers.
What This Product Does:
The exhaust headers collect combustion gases leaving the engine's cylinders and direct them towards the turbochargers.
On the twin-turbocharged GT2 RS, exhaust gas energy drives the turbine wheels that generate boost. Efficient exhaust flow before the turbochargers is therefore important for both engine breathing and turbo response.
The Fabspeed Sport Headers are designed to:
- Improve exhaust gas flow
- Reduce restriction before the turbochargers
- Improve exhaust scavenging
- Deliver exhaust gases more efficiently to the turbochargers
- Support faster turbo boost response
- Improve throttle response
- Support increased engine performance
- Replace ageing factory exhaust manifolds
- Provide durable stainless-steel construction
- Maintain smooth internal flow through mandrel-bent tubing
The high-velocity 3-into-1 merge collectors are designed to combine exhaust pulses smoothly and efficiently before the gases enter the turbochargers.
Symptoms Of Wear Or Failure:
Exhaust headers operate in an extremely demanding environment and are continually subjected to high temperatures, vibration and repeated thermal cycling.
Common signs of damaged or deteriorating headers include:
- Ticking or tapping noises, particularly during a cold start
- Blowing or hissing noises from the manifold area
- Black soot deposits around header joints
- Visible cracks in the manifold or welds
- Exhaust leaks around the cylinder-head flanges
- Warped or distorted mounting flanges
- Broken or heavily corroded studs and nuts
- Increased exhaust noise
- Exhaust fumes around the engine compartment
- Reduced throttle response
- Slower or inconsistent turbo response
- Loss of engine performance
- Increased heat around nearby engine components
Similar symptoms can also be caused by failed exhaust gaskets, loose fasteners or leaks elsewhere in the exhaust system, so the complete assembly should be inspected before replacement.
Why Replacement Matters:
A secure and leak-free exhaust route between the cylinder heads and turbochargers is particularly important on a high-performance turbocharged engine.
If a header cracks or develops a leaking flange, exhaust gases can escape before they reach the turbocharger. This reduces the amount of exhaust energy available to drive the turbine and may contribute to slower boost response and reduced performance.
Escaping gases can also expose surrounding components to excessive heat and produce unwanted exhaust noise.
Replacing damaged headers helps restore:
- A sealed exhaust path
- Efficient exhaust delivery to the turbochargers
- Consistent turbocharger response
- Correct exhaust gas flow
- Reduced exhaust leakage
- Improved reliability around the manifold area
For vehicles with serviceable factory headers, upgrading to the Fabspeed system provides a freer-flowing design intended to improve exhaust scavenging, throttle response and turbo boost response.
