Product Description

 

 

The Soul Competition Headers for the 718 GT4 RS / Spyder RS replace the restrictive factory header assembly with a true free‑flowing, full‑flow long‑tube stainless setup, unlocking the flat‑six’s potential for more power, sharper throttle response, and a raw, aggressive exhaust character. Weighing in several pounds lighter than stock, they drastically improve exhaust flow and help the engine breathe easier — ideal for track days, spirited driving, or a full performance build. Install is direct‑bolt, and they’re engineered to pair seamlessly with factory or aftermarket Over‑Axle Pipes to complete a full 3‑inch exhaust flow path from headers to tips.

Fitment Notes

  • Built specifically for Porsche 718 GT4 RS / Spyder RS (from 2022 onward). 

  • Direct‑bolt replacement for the OEM header assembly — uses factory exhaust ports and attaches to stock or upgraded Over‑Axle Pipes.

  • Because these are high-flow “competition” headers (no cats on the header section), expect exhaust to be aggressive and engine management may require tuning, especially if running full exhaust/downpipe upgrades.

Included

  • Full set of mandrel‑bent stainless‑steel headers with precision cast‑flanges and a large merge collector, all built in‑house in the USA. 

  • All required hardware and OEM-style gaskets for a bolt‑on install — no fabrication or custom modification needed.

Product Specs

  • Material & Construction: Thick‑wall (.065″) T304L stainless steel; back‑purged TIG‑welded for strength and longevity.

  • Weight Savings: ~ 4.5 lb (approx. 2 kg) lighter than factory headers (17.75 lb vs ~22.2 lb OEM) — reducing rotational and unsprung mass. 

  • Flow Design: Long‑tube runners, smooth radius bends, large merge collector — engineered to maximize exhaust velocity and match a full 3″ flow path when paired with Over‑Axle Pipes. 

  • Build Tolerance: Exhaust flanges water‑jet‑cut to ISO 9001:2015 standards, with ±0.003" tolerance for precise fitment.

Product Features

  • Improved Exhaust Flow & Engine Breathing — Large-diameter, long‑tube header design reduces back-pressure and improves scavenging, letting the 4.0 L flat-six rev more freely and deliver more power under load. 

  • Sharper Throttle Response & Mid‑Range Punch — Reduced exhaust restriction helps the engine respond more quickly to throttle inputs, improving driveability and acceleration feel even without additional mods. 

  • Weight Reduction & Crisper Handling Feel — Lighter than OEM headers, lowering the rotational mass and aiding drivetrain response, which helps with throttle modulation and overall dynamic feel. 

  • Aggressive, Race‑Inspired Exhaust Tone — Combined with free-flow rear piping, these headers help unlock a raw, high‑revving exhaust note that matches the RS’s motorsport DNA. 

  • Bolt‑On, OEM‑Style Fitment — Designed for direct fitment to stock exhaust ports and compatible with factory or aftermarket over‑axle pipes — straightforward install for experienced shops or confident DIYers.

  • Built for Street and Track — Manufactured from track‑grade stainless steel with quality‑controlled construction and backed by Soul’s Lifetime Warranty — suitable for daily driving or high‑stress track use.
