Exhaust bolt repair kit for Boxster / 996 / 997 Carrera & Cayman Gen1 1997- 2009 (Not GT3, GT2 or TT engines)



With more and more broken exhaust bolts reported on the water-cooled engines, the headache of repairing a broken bolt is becoming epidemic. Tasks ranging from a simple exhaust system update through an engine removal, are consistently plagued by snapped, rusted, and broken exhaust manifold bolts. Rarely can an accurate removal of the broken bolt be performed with the engine in the car, and even after removal, the task is time consuming and if not done carefully can lead to a damaged head or faulty repair. STOMSKI RACING's answer to these problems is the SR067, a kit that easily, accurately, and flexibly allows you to drill out the broken bolts - with the engine still in the car- saving time and headaches. A CNC milled plate indexes precisely off the broken bolts and/or bolt holes. Using our uniquely designed Thumb Screws, the SR067 plate is locked in place (by threading a Thumb Screw over a broken bolt or by using a supplied bolt threaded through the SR067 Thumb Screw). With the included pilot drills and drill guides, the faulty bolt can be drilled out, producing a perfectly perpendicular and centered hole that if necessary can be chased with an included M8x1.25 tap.

Kit includes : anodized aluminum fixture, drill bits, tap with extension, drill jigs/guides, Thumb Screws, and hardware in a sturdy storage case.

Now also includes our SR065D drill guide.

These titanium components are resistant to rust and corrosion, which can be a common issue with traditional steel studs and nuts. This corrosion resistance ensures that the studs and nuts maintain their integrity, allowing for easy removal and installation when necessary. They are the perfect upgrade for Porsche enthusiasts who demand the ease of access to vehicle's exhaust system.

Titanium exhaust manifold bolt M8x27. 
Set of 12  (OE Ref: 99907358901) 



Titanium is a highly corrosion-resistant material, which is particularly important in exhaust systems due to the exposure to extreme heat and moisture. The corrosion resistance of titanium bolts ensures longevity and reduces the risk of premature failure, ultimately saving the owner from costly repairs.

Fabspeed Race Headers.
The Fabspeed Porsche 986 Boxster Race Headers are a competition-focused exhaust upgrade designed for maximum exhaust flow, improved scavenging, reduced restriction and sharper engine response on 2000–2004 Porsche 986.2 Boxster and Boxster S models.

Fits:

• Porsche Boxster 986 2.7L 2000-02
• Porsche Boxster S 986 3.2L 2000-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04  

Unlike Fabspeed's Sport Headers, these Race Headers do not contain catalytic converters. They replace the factory Porsche headers and their integrated primary catalysts with free-flowing equal-length headers, making them intended specifically for closed-course competition, race and off-road applications.

Constructed from equal-length T304 stainless-steel CNC mandrel-bent tubing, the headers use F1-style merge collectors to improve exhaust-gas velocity and scavenging. They can be used with the factory rear muffler or compatible aftermarket cat-back exhaust systems designed around the OEM mounting arrangement.

What This Product Does:
Headers collect exhaust gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.

The design, length and geometry of the individual primary tubes influence how efficiently these gases leave each cylinder.

The Fabspeed Race Headers replace the original catalyst-equipped manifolds with a freer-flowing, equal-length arrangement.

They are designed to provide:

• Maximum exhaust-gas flow
• Reduced exhaust restriction
• Reduced backpressure
• Improved exhaust scavenging
• Improved cylinder evacuation
• Increased performance potential
• Sharper throttle response
• Improved high-RPM breathing
• Reduced exhaust-system weight
• More aggressive flat-six exhaust sound

Removes The Factory Catalytic Converters:

• On 2000–2004 Porsche 986 Boxster models, the factory headers incorporate primary catalytic converters.
• The Fabspeed Race Headers remove these catalysts entirely.
• This creates a substantially less restrictive exhaust path but also means the product is fundamentally different from a street-oriented catalyst-equipped replacement header.
• The Race Headers are intended for vehicles where maximum exhaust flow is prioritised over emissions-system compatibility.

Why Upgrading Matters:
The factory headers do not need to have failed before installing this product.

These Race Headers are primarily a competition performance upgrade.

Reasons for upgrading include:

• Removes restrictive OEM catalytic converters
• Maximum exhaust-flow design
• Equal-length primary tubes
• T304 stainless-steel construction
• CNC mandrel-bent tubing
• F1-style merge collectors
• Improved exhaust scavenging
• Reduced exhaust backpressure
• Improved throttle response
• Increased performance potential
• Reduced exhaust-system weight
• More aggressive flat-six sound
• O2 sensor bungs incorporated
• Compatible with factory rear muffler
• Compatible with OEM-style aftermarket cat-back exhausts
• Direct replacement installation
• No cutting or welding required

Fabspeed Sport Headers.
The Fabspeed Porsche 986 Boxster Sport Headers are a performance exhaust upgrade designed to improve exhaust flow, scavenging, throttle response and flat-six sound on Porsche 986 Boxster and Boxster S models from 2000–2004.

Fits:

• Porsche Boxster 986 2.7L 2000-02
• Porsche Boxster S 986 3.2L 2000-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04  

The headers use equal-length CNC mandrel-bent primary tubes combined with F1-style high-velocity merge collectors. This configuration is designed to improve the way exhaust gases leave each cylinder and merge into the exhaust system, reducing unnecessary restriction and supporting more efficient engine breathing.

2000–2004 Porsche 986 Boxster / Boxster S: The original headers incorporate primary catalytic converters. Fabspeed therefore supplies these applications with 200-cell HJS Sport Catalytic Converters.

Fabspeed reports +8 wheel horsepower and +4 lb-ft of torque when the Sport Headers are installed with the Fabspeed Maxflo Performance Exhaust System. These are manufacturer-reported figures from a specific vehicle and are not guaranteed results for every application.

What This Product Does:
Exhaust headers collect combustion gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.

The design and length of the individual primary tubes influence how efficiently these exhaust pulses leave the cylinders.

The Fabspeed Sport Headers are designed to improve this process through equal-length primary tubing and high-velocity merge collectors.

Potential benefits include:

• Improved exhaust flow
• Improved exhaust scavenging
• Reduced exhaust restriction
• Improved cylinder evacuation
• Sharper throttle response
• Increased horsepower and torque potential
• Stronger high-RPM performance
• Enhanced naturally aspirated flat-six sound

2000-2004 Header With HJS Sport Catalysts: 

For 2000–2004 Porsche 986 Boxster and Boxster S models, the original Porsche headers incorporate primary catalytic converters.

Fabspeed's replacement headers for these vehicles therefore incorporate 200-cell HJS Sport Catalytic Converters.

The lower-density sport catalyst design is intended to provide greater exhaust flow than a more restrictive conventional catalyst while retaining catalytic converter functionality.

Potential benefits include:

• Reduced catalyst restriction
• Improved exhaust flow
• Reduced backpressure
• Improved performance potential
• Stronger exhaust sound

Why Upgrading Matters:
The original Porsche headers do not need to have failed before fitting the Fabspeed Sport Headers.

This product is primarily a performance and sound upgrade.

Reasons for upgrading include:

• Equal-length primary tubes
• CNC mandrel-bent construction
• F1-style high-velocity merge collectors
• Improved exhaust scavenging
• Improved exhaust flow
• Reduced exhaust restriction
• Increased performance potential
• Sharper throttle response
• Enhanced flat-six exhaust sound
• 200-cell HJS Sport Catalytic Converters on 2000–2004 versions  
• Bolt-on installation
• Designed specifically for Porsche 986 Boxster and Boxster S models
