The Fabspeed Spec Boxster Competition Race Exhaust System is a lightweight, high-flow exhaust package developed specifically for 1997–1999 Porsche 986 Boxster and Boxster S track and competition applications.
Fits:
- Porsche Boxster 986 2.5L 1997-99
- Porsche Boxster 986 2.7L 1999
- Porsche Boxster S 986 3.2L 1999
Designed with maximum exhaust flow, weight reduction and performance in mind, the system replaces the restrictive factory exhaust and catalytic-converter arrangement with a much freer-flowing race configuration.
Fabspeed manufactures the system from 14–16 gauge CNC mandrel-bent T304 stainless steel, providing excellent resistance to exhaust heat, corrosion and repeated track-day thermal cycling.
The system also includes turn-down exhaust tips, designed to help direct sound toward the ground and assist with track noise-limit compliance.
Fabspeed currently publishes performance figures of approximately:
- +15 hp
- +14 lb-ft of torque
- 36 lb / 16.4 kg weight reduction
Actual performance will vary according to vehicle condition, engine specification, fuel and testing conditions.
What This Product Does:
The factory exhaust system must balance noise, emissions, refinement and performance.
For a dedicated competition car, these compromises can create unnecessary weight and exhaust restriction.
The Fabspeed Spec Boxster Competition system is designed to:
- Maximise exhaust gas flow
- Reduce backpressure
- Improve throttle response
- Increase horsepower and torque
- Reduce rear vehicle weight
- Produce a much more aggressive race exhaust note
- Remove the restrictive factory catalytic converters
- Provide a lightweight track-focused exhaust layout
- Direct exhaust sound downward through turn-down tips
- Replace the full OEM exhaust with a competition-oriented system
This system is specifically intended for race and track use, rather than normal road driving.
Symptoms Of Wear Or Failure:
The factory 986 exhaust system is now several decades old on early cars and can deteriorate through heat, condensation, corrosion and vibration.
Common symptoms include:
- Rust or corrosion on exhaust pipes and silencers
- Cracked welds
- Blowing or hissing noises
- Black soot around leaking joints
- Internal muffler rattles
- Loose internal baffles
- Catalyst rattling
- Reduced engine performance
- Restricted high-RPM response
- Excessive exhaust heat
- Loose clamps or brackets
- Damaged exhaust hangers
- Dented or distorted pipework
- Exhaust fumes around the rear of the vehicle
- Poor exhaust-tip alignment
- Check Engine Light caused by catalyst-related faults
Rattling or reduced performance may also be caused by heat shields, oxygen sensors or other engine-management issues, so proper diagnosis is recommended.
Why Replacement Matters:
A deteriorated exhaust system can affect both performance and reliability.
Cracked or leaking exhaust components can allow extremely hot gases to escape near surrounding parts.
Restricted or internally damaged catalytic converters can also increase exhaust backpressure.
Continued operation with a failing exhaust can contribute to:
- Reduced engine performance
- Poor throttle response
- Excessive exhaust heat
- Unwanted noise and rattling
- Exhaust fumes escaping before the intended outlet
- Heat exposure to nearby components
- Additional stress on exhaust mounts and joints
Replacing damaged components restores secure exhaust routing and correct exhaust flow.
For a healthy standard car, the Fabspeed Competition system is primarily a race-performance and weight-reduction upgrade.
