Product Description

 

 

The Soul Performance Long Tube Street Headers for the Porsche 981 Boxster and Cayman (2013–2016) are a premium, performance-oriented header upgrade that dramatically improves exhaust flow, throttle response, and flat-six character. Built around large-diameter, free-flowing catalytic converters and long tube runners that are specifically sized for the 3.4L / 2.7L engines, this system is designed to yield noticeable gains in mid-range power while enhancing exhaust tone versus the restrictive factory manifolds — all without throwing a check engine light on most OBD2 vehicles. These headers offer a more aggressive exhaust note and freer rev-up experience, making them a compelling upgrade for enthusiasts seeking refined performance and sound.

Fitment Notes

  • Direct bolt-on fit for Porsche 981 Cayman and Boxster models from 2013–2016.

  • Designed to replace stock headers while retaining mid-section exhaust and downstream components.

  • Includes free-flowing HJS 200-cell catalytic converters sized for this platform, helping avoid a check engine light without custom tuning.

  • Intended for off-road use only in CARB states (not CARB certified). Confirm local emissions regulations before installation.

Included

  • Pair of long tube street headers with integrated high-flow cats.

  • Precision machined flanges and gasket set for direct OEM-style mating.

  • Mounting hardware and detailed installation instructions.

Product Specs

  • Catalytic Converters: HJS 200-cell high-flow cats to balance performance and emissions; designed to reduce chances of a CEL.

  • Warranty: Backed by Soul’s Lifetime Warranty for both street and track use.

Product Features

  • Free-flowing long tube design enhances exhaust scavenging for quicker engine response and improved mid-range torque.

  • Large diameter catalytic cores maintain emissions functionality and reduce the likelihood of a check engine light on most OBD2 vehicles.

  • Improved exhaust tone delivers a deeper, more engaging flat-six sound character without excessive drone.

  • Precision fitment and construction ensure a quality installation that integrates with stock or aftermarket exhaust components.
