The SOUL Competition Headers transform one of the most restrictive sections of the Porsche 981 Boxster and Cayman exhaust system. Replacing the heavy factory manifolds and catalytic converters with a free-flowing, catless header design reduces restriction, removes approximately 11 lbs from the vehicle, and allows substantially more of the naturally aspirated flat-six character to come through.
SOUL developed these headers specifically for the 981 platform, using 2-inch primary runners and properly sized collectors to improve exhaust flow and engine response. While the system was optimized around the 3.4L engine found in the Cayman S and Boxster S, SOUL designed the same architecture to provide meaningful improvements on the 2.7L engine as well.
Port-matched flanges, smooth-radius primary tubing, and performance-oriented collectors work together to improve exhaust flow through the complete header assembly. Removing the factory catalytic converters also produces a considerably more aggressive exhaust note and allows the engine to respond more freely throughout the rev range.
For owners looking to extract more sound and performance from a naturally aspirated 981 while significantly reducing exhaust restriction and weight, the Competition Headers are one of the most substantial exhaust upgrades available for the platform.
Fits 2013–2016 Porsche 981 Boxster and Cayman models
Compatible with both 2.7L and 3.4L naturally aspirated flat-six engines
Complete catless replacement for the factory exhaust manifolds and catalytic converters
Features 2-inch primary runners developed specifically for the Porsche 981 platform
Runner and collector geometry optimized to improve exhaust flow and engine response
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 improve the transition from the individual primary tubes into the remainder of the exhaust system
Saves approximately 11 lbs compared with the factory exhaust manifolds and catalytic converters
Produces a substantially more aggressive flat-six exhaust note
Constructed from 14–16 gauge T304L stainless steel tubing
Direct bolt-on installation
Each system is fixture-tested prior to shipment to help ensure accurate fitment
New high-grade installation hardware included
Installation instructions included
Backed by SOUL Performance Products' Lifetime Warranty for both street and track use
The SOUL Competition Headers remove the factory catalytic converters and may trigger a check engine light as a result.
SOUL recommends an appropriate ECU calibration for vehicles using these headers to address catalyst-related fault codes. ECU tuning may also allow the engine to better take advantage of the increased exhaust flow provided by the catless header configuration.
Optional O2 sensor spacers are available, but they should not be considered a guaranteed method of preventing catalyst-efficiency fault codes.
Optional O2 sensor spacers are available for customers who would like them included with the Competition Headers.
O2 spacers reposition the downstream oxygen sensors farther from the direct exhaust stream and may reduce the likelihood of catalyst-efficiency fault codes in some applications. Results can vary by vehicle and calibration, and DasMotoring does not guarantee that O2 spacers will prevent a check engine light.
The SOUL Competition Headers remove the factory catalytic converters and are not CARB certified. SOUL identifies this product as intended for off-road use due to removal of the factory catalytic converters.
Customers are responsible for ensuring compliance with all applicable local, state, and federal regulations before installation or use.
