The SOUL Long Tube Street Headers are designed for Porsche 987.2 Boxster and Cayman owners looking to improve exhaust flow, throttle response, performance, and naturally aspirated flat-six sound while retaining catalytic converters. Replacing the restrictive factory header assemblies with properly sized long-tube runners, optimized collectors, and large-diameter free-flowing catalytic converters creates a more efficient exhaust path without moving to a fully catless configuration.
SOUL developed this application specifically for the 987.2 platform using 2-inch primary runners. Runner and collector sizing was optimized around the 3.4L engine while also providing performance improvements for the 2.9L flat-six. Port-matched flanges, smooth-radius primary tubing, and performance-oriented collectors work together to improve exhaust flow from the cylinder heads through the remainder of the exhaust system.
SOUL reports maximum gains of approximately 8 wheel horsepower and 11 lb-ft of torque at 4,100 RPM when the headers are paired with the SOUL Valved Exhaust System and tested on a Cayman S. Actual results will vary depending on vehicle condition, transmission, fuel, environmental conditions, ECU calibration, and supporting modifications.
The SOUL Street Headers also reduce weight compared with the factory assemblies. The factory headers weigh approximately 26.25 lbs, while the SOUL headers weigh approximately 24.45 lbs, saving approximately 1.8 lbs.
For owners who want improved response, performance, and flat-six sound while retaining catalytic converters and avoiding the compromises of a fully catless exhaust system, the SOUL Long Tube Street Headers provide a strong street-oriented solution.
Fits 2009–2012 Porsche 987.2 Boxster, Boxster S, Cayman, Cayman S, Boxster Spyder, and Cayman R
Compatible with 2.9L and 3.4L naturally aspirated flat-six engines
Includes fitment for the higher-performance Boxster Spyder and Cayman R models where equipped with the 3.4L engine
SOUL specifies fitment for all 2009–2012 987.2 Boxster and Cayman vehicles and states that the header design produces gains on both the 2.9L and 3.4L engines.
Long-tube header architecture developed specifically for the Porsche 987.2 platform
Features 2-inch primary runners
Runner and collector sizing optimized around the 3.4L engine while also providing performance improvements for the 2.9L
Large-diameter, free-flowing catalytic converters retain a catted exhaust configuration
Designed to improve exhaust flow, throttle response, power delivery, and naturally aspirated flat-six sound

Designed by SOUL to provide increased performance without triggering a check engine light
Weighs approximately 24.45 lbs compared with approximately 26.25 lbs for the factory header assemblies
Saves approximately 1.8 lbs / 0.8 kg compared with the factory headers
Port-matched flanges provide a smooth transition from the cylinder head into the primary runners
Smooth-radius primary tubing helps minimize unnecessary exhaust restriction
Performance-oriented collectors optimize exhaust flow through the header assembly
Constructed from T304L stainless steel
Each header set is rigorously quality-checked in-house
Direct bolt-on installation
Each set is fixture-tested prior to shipment to help ensure accurate fitment
New high-grade hardware for the header-to-exhaust flanges included
Detailed installation instructions included

Backed by SOUL Performance Products' Lifetime Warranty for both street and track use
SOUL developed the 987.2 Long Tube Street Headers around 2-inch primary runners and appropriately sized collectors to improve exhaust flow from both the 2.9L and 3.4L engines.
Testing on a Cayman S equipped with the SOUL Valved Exhaust System demonstrated maximum gains of approximately 8 wheel horsepower and 11 lb-ft of torque at 4,100 RPM.
An ECU tune is not required for installation. Additional performance may be possible when the freer-flowing headers are combined with an appropriate ECU calibration and supporting modifications.
The SOUL Long Tube Street Headers retain catalytic converters and are specifically designed to provide increased exhaust flow and performance without triggering a check engine light.
As with any emissions-related component, vehicle condition, oxygen-sensor health, ECU calibration, and additional modifications can influence catalyst monitoring. DasMotoring does not guarantee that a check engine light can never occur.
The SOUL Long Tube Street Headers retain large-diameter, free-flowing catalytic converters while improving runner geometry, collector design, exhaust flow, throttle response, and flat-six sound.
The SOUL Competition Headers eliminate the catalytic converters entirely for a less restrictive exhaust path, reduced weight, and a more aggressive exhaust configuration.
For owners who want improved performance and exhaust character while retaining catalytic converters, the Long Tube Street Headers provide the more street-oriented solution. For vehicles built around a fully catless exhaust configuration, the Competition Headers provide the more aggressive alternative.
A SOUL Copper Header Gasket Set can be added for customers replacing old or worn factory gaskets during installation.
The 987.2 gasket kit includes four approximately 1 mm-thick copper gaskets:
(2) Header-to-Head gaskets
(2) Header-to-Exhaust gaskets
SOUL specifies that these copper gaskets should not be reused after installation. The complete gasket set is available as a $65 option.
These headers retain catalytic converters; however, the product is not CARB certified and may not be legal for use on emissions-controlled vehicles. SOUL identifies the product as intended for off-road use only.
Customers are responsible for ensuring compliance with all applicable local, state, and federal regulations before installation or use.
