Soul Competition Exhaust Headers for Porsche 981 Boxster and Cayman (2013–2016)

Description

The Soul 981 Competition Headers replace the restrictive factory manifolds with a free‑flowing, performance‑optimized stainless header system — dramatically improving exhaust flow and engine breathing. By shedding roughly 11 lb of exhaust weight and unlocking a smoother, more aggressive flat‑six exhaust tone, they sharpen throttle response, increase mid-range punch, and add a serious edge to driving dynamics. Whether you’re tuned for street, weekend canyon runs, or track days, these headers deliver a rawer, more race‑inspired character with proven power gains.

Fitment Notes

• Designed to fit Porsche 981 Boxster / 981 Cayman, model years 2013–2016 (all trim levels).

• Direct bolt‑on installation — uses OEM exhaust ports and mounting geometry, no cutting or fabrication required. 

• Because these are “competition” headers (cat/bypass style), installation may trigger a check‑engine light unless ECU or O₂‑sensor handling is addressed.

Included

• Full set of stainless‑steel long‑tube headers with mandrel‑bent 2″ runners and optimized merge collector.

• All necessary hardware, gaskets, and flanges for a complete bolt‑on swap. 

• Detailed installation instructions to guide you or your shop through the swap.

Product Specs

• Material: T304L stainless steel, mandrel‑bent tubing with smooth bends and port‑matched flanges.

• Weight savings: Approximately 11 lb lighter than stock manifolds — reducing unsprung/rotating mass for snappier response. 

• Flow optimization: Runner and collector geometry designed for maximum exhaust scavenging and minimal back‑pressure, tuned for the 2.7 L and 3.4 L flat‑six engines. 

• Sound & Performance Gains: Dyno-tested gains of about +26 wheel‑horsepower (whp) and +24 ft‑lb torque on a 981 Cayman S (when combined with supporting mods).

Product Features

• Significantly improved exhaust flow & response — Mandrel‑bent, free‑flow runners and optimized collector geometry allow exhaust gases to evacuate faster, reducing back‑pressure and improving throttle response and mid-range power delivery.

• Weight reduction for sharper handling — Shedding 11 lb from the exhaust manifold system reduces mass and helps improve throttle response, rotational inertia, and engine responsiveness.

• Raw, race‑inspired exhaust tone and character — With freer flow and less restriction, the flat‑six exhaust gains a deeper, more aggressive voice — especially under throttle and on overrun — giving a much more thrilling driving experience.

• Direct bolt‑on fitment — Easily replaces stock manifolds using OEM mounting points and flanges, making installation straightforward without custom fabrication.

• Strong foundation for future mods — By improving exhaust flow and efficiency at the header, these headers support further performance upgrades (intake, exhaust, tune) and make downstream components more effective.

• Proven dyno gains — The tested increases in horsepower and torque make these headers a performance‑driven upgrade, not just an aesthetic or acoustic mod.
