DesignTek Complete Sports Exhaust Set for Porsche 997.1 Carrera 3.6L / 3.8L
Upgrade the complete exhaust system on your Porsche 911 Type 997.1 Carrera with this comprehensive DesignTek stainless-steel sports exhaust package, combining performance headers, high-flow 200-cell catalytic converters, sports rear silencers and polished quad tailpipes.
Fits:
Porsche 997.1 Carrera 2 3.6L 2005-08
Porsche 997.1 Carrera 4 3.6L 2005-08
Porsche 997.1 Carrera 2S 3.8L 2005-08
Porsche 997.1 Carrera 4S 3.8L 2005-08
Designed as a complete performance exhaust solution for the naturally aspirated 3.6L and 3.8L Porsche 997.1 Carrera, the package improves exhaust-gas flow from the cylinder heads through to the rear outlets while producing a deeper, more purposeful sports exhaust note.
Rather than upgrading only one section of the exhaust, this package replaces the major restrictive components throughout the system, making it particularly suitable for performance road builds, track cars and vehicles undergoing a complete exhaust-system overhaul.
Kit Includes
The complete DesignTek exhaust package contains:
1 × Pair DesignTek Exhaust Manifolds / Headers – 3606309601
- Left and right headers
- High-grade 304 stainless-steel construction
- Performance merger collector design

- Supplied with two triangular flange gaskets
- Nuts and bolts included
1 × DesignTek 200-Cell Sports Catalytic Converter Set – 3606109977
- High-flow 200-cell catalytic converters
- Approx. 2.5" / 63.5 mm main bore
- German-manufactured 200-cell catalyst cores
- 40G catalyst loading
- Mandrel-bent construction
- Designed to taper down to the original 54 mm exhaust connection
- Supplied with required joiners and clamps
1 × Pair DesignTek Sports Rear Mufflers / Silencers – 3606009702
- Left and right sports silencers
- T304 stainless-steel construction
- 14–16 gauge material
- Mirror-polished finish
- 2.25" / 58 mm outlet flange
- Designed for a deeper, more aggressive sports exhaust sound
1 × Pair DesignTek Polished Quad Tailpipes – 3606409703
- Polished stainless-steel construction
- Quad-outlet appearance
- Factory-inspired Carrera S-style design
- Supplied as left and right pair
- Adaptor rings included for 3.6L and 3.8L applications
Complete Exhaust Upgrade
This package upgrades the exhaust flow path from the cylinder heads through to the tailpipes.
The combination of freer-flowing headers, larger-bore sports catalysts and performance rear silencers is designed to reduce unnecessary exhaust restriction while enhancing the character of the naturally aspirated flat-six engine.
Potential benefits include:
- Improved exhaust-gas flow
- Sharper engine response
- More purposeful sports exhaust tone
- Reduced restriction compared with the standard exhaust system
- Stainless-steel durability
- Improved rear-end appearance
- Greater potential when combined with suitable
- ECU calibration
200-Cell High-Flow Sports Catalysts
The DesignTek 3606109977 sports catalytic converter set uses high-quality German-manufactured 200-cell, 40G-loaded catalyst cores.
The larger approximately 63.5 mm / 2.5-inch bore is designed to provide greater gas-flow capacity than the standard system while retaining catalytic converter construction.
The system tapers down to meet the original 54 mm pipework, helping simplify installation.
Mandrel-bent pipework is used to maintain smooth internal bends and promote efficient flow through the system.
Compared with the standard catalysts, the DesignTek 200-cell units are designed to provide:
- Increased exhaust-gas flow
- Reduced exhaust restriction
- Sportier exhaust tone
- Improved performance potential
- Faster-flowing performance catalyst construction

Porsche Sport Silencers & Mufflers - Performance Sound & Exhaust Upgrades
Sport Silencers / Mufflers are designed to enhance the sound, performance, and driving character of your Porsche by improving exhaust gas flow and delivering a more engaging exhaust note. Compared to standard exhaust silencers, sports mufflers reduce restriction, sharpen throttle response, and provide a sportier tone that better reflects Porsche’s performance heritage.
Available from Design911, this category includes both genuine Porsche sport exhaust components and high-quality aftermarket performance mufflers, giving owners the choice between factory-engineered authenticity and performance-focused customisation.
What Do Sport Silencers / Mufflers Do?
Sport silencers optimise exhaust flow while enhancing sound quality.
Core Functions:
- Reduce exhaust backpressure for improved engine breathing.
- Enhance throttle response and power delivery.
- Produce a deeper, sportier exhaust note.
- Improve exhaust efficiency and flow dynamics.
- Enhance the overall driving experience.
A well-designed sports muffler balances performance gains with refined sound control.
Why Do Standard Exhaust Silencers Fail or Fall Short?
Standard exhaust mufflers are designed primarily for noise
reduction, emissions compliance, and longevity. Over time, common issues
include:
- Internal corrosion from condensation and heat cycles.
- Restrictive baffling limiting exhaust flow.
- Dull or muted exhaust sound.
- Internal baffle breakdown causing rattles.
- Reduced efficiency when paired with performance upgrades.
As these components age, both performance and sound quality can deteriorate.
Why Upgrade to Sport Silencers / Mufflers?
Sport silencers are engineered to improve both performance and auditory feedback.
Upgrade Benefits:
- Improved exhaust flow and reduced restriction.
- Enhanced exhaust sound without excessive drone.
- Increased driving engagement and responsiveness.
- Available in OEM Porsche or performance aftermarket options.
- Ideal for road, touring, and spirited driving.
Upgrading delivers a more exciting exhaust character while supporting engine efficiency.
Highlights
- Porsche sport silencer and muffler upgrades
- OEM Porsche and premium aftermarket options
- Improved exhaust sound, flow, and performance
- Designed for performance-focused driving
- High-quality materials for durability and reliability
