This kit is comprised of the following items:
- Porsche 997 MK1 Carrera 2 3.6L 2005-08
- Porsche 997 MK1 Carrera 4 3.6L 2005-08
The Fabspeed Porsche 997 Carrera Performance Package is a comprehensive intake, exhaust developed for Porsche 997 Carrera models from 2005–2008.
Fits:
- Porsche 997 MK1 Carrera 2 3.6L 2005-08
- Porsche 997 MK1 Carrera 4 3.6L 2005-08
Rather than upgrading one component in isolation, the package improves the complete airflow path through the naturally aspirated flat-six engine. It replaces restrictive factory intake and exhaust components with freer-flowing Fabspeed hardware.
Package Includes:
- Fabspeed Sport Headers
- Sport Catalytic Converter X-Pipe
- High-flow sport catalysts
- Maxflo Performance Mufflers
- Deluxe Quad-Style Exhaust Tips
- Carbon Fiber Competition Air Intake System
What This Product Does:
The Performance Package is designed to improve how efficiently air enters the engine and how quickly exhaust gases leave it.
The upgraded intake reduces restriction before the engine, while the headers, X-pipe and mufflers provide a freer-flowing exhaust path.
The ECU calibration then adjusts engine-management parameters to take advantage of the increased airflow.
The package is designed to:
- Increase horsepower
- Increase torque
- Improve throttle response
- Improve engine breathing
- Increase cold-air intake flow
- Reduce exhaust restriction
- Improve performance throughout the RPM range
- Produce a deeper and more aggressive exhaust note
- Increase induction sound
- Reduce overall component weight
For a mechanically healthy standard car, this package is primarily a performance, sound and response upgrade, rather than a maintenance replacement.
Symptoms Of Wear Or Failure:
The original exhaust components on a 2005–2008 Porsche 997 may deteriorate through age, heat cycling, corrosion and mileage.
Possible symptoms include:
- Exhaust blowing or ticking
- Hissing from leaking joints
- Black soot around exhaust connections
- Cracked welds
- Corroded pipes
- Loose heat shields
- Internal muffler rattling
- Catalyst rattling
- Reduced high-RPM performance
- Excessive exhaust heat
- Damaged exhaust brackets
- Poor exhaust-tip alignment
- Check Engine Light from catalyst-efficiency faults
A rattling or restricted catalyst may significantly affect engine performance even if the outer catalyst housing appears intact.
Why Replacement / Upgrading Matters:
If the original intake or exhaust components are worn or damaged, replacement can help restore:
- Correct exhaust sealing
- Reliable intake airflow
- Proper engine breathing
- Correct exhaust routing
- Secure mounting
- Consistent throttle response
A leaking exhaust or damaged catalyst can reduce performance and create excessive heat around surrounding components.
A cracked intake component can allow unmetered air into the engine, potentially causing poor running or fault codes.
However, where the factory components remain serviceable, the Fabspeed Performance Package is primarily an upgrade intended to increase airflow, performance, sound and driver response.

Exhaust System Packages for Porsche | Performance, Precision & Sound
A well-designed exhaust system package is essential for maintaining your Porsche’s performance, efficiency, and distinctive exhaust tone. These complete systems replace worn or restrictive exhaust components with precision-engineered, high-flow assemblies that restore or enhance power delivery and sound quality.
At Design911, we offer a comprehensive selection of exhaust system packages for Porsche models — from classic 911s to modern GT-series vehicles. Each package includes key components such as silencers, manifolds, catalytic converters, and pipework, designed for optimal gas flow, reduced back pressure, and improved throttle response.
Manufactured from premium stainless steel, Inconel, or titanium, our exhaust kits are built for durability, corrosion resistance, and superior acoustic performance. Whether you’re restoring a vintage air-cooled model or tuning your track-ready GT3, these exhaust systems deliver a perfect balance of reliability, performance, and sound.
What Do Exhaust System Packages Do?
An exhaust system package channels exhaust gases away from the engine efficiently while controlling noise and emissions. A properly designed system ensures optimal engine breathing — improving power, torque, and overall efficiency.
Core Functions:
- Directs
exhaust gases safely from the engine.
- Reduces
back pressure to maximise power output.
- Controls
emissions via catalytic converters and mufflers.
- Enhances
exhaust tone for an authentic Porsche sound.
- Optimises gas flow for performance and reliability.
An upgraded exhaust system can also provide weight reduction, improved throttle response, and enhanced driving enjoyment.
Why Do Exhaust Systems Fail?
Over time, even the most durable exhaust systems deteriorate due to constant exposure to heat, vibration, and the elements.
Common Causes of Exhaust System Failure Include:
Corrosion
and rust, especially on mild steel systems.
When exhaust components fail, you may notice rattling sounds, loss of performance, strong fumes, or increased fuel consumption — all signs that replacement is needed.
Why Replace or Upgrade Your Exhaust System?
Replacing or upgrading your Porsche’s exhaust system ensures maximum performance, efficiency, and driving enjoyment.
Key Benefits:
- Restores optimal gas flow and back pressure.
