Product Description

The SOUL Street Headers for the 997 GT3 replace the restrictive factory exhaust manifolds with large-diameter, free-flowing runners and optimized catalytic-converter integration — unlocking stronger throttle response, more mid-range punch, and a richer exhaust tone. Built from mandrel-bent T304L stainless, these headers sharpen exhaust flow and reinforce the GT3’s hallmark high-revving flat-six character. The upgrade delivers noticeable performance and sound improvements while retaining usability for street driving or spirited weekend runs.

Fitment Notes

  • Designed for Porsche 997 GT3 / GT3 RS (all 997-generation GT3s, 2006-2012) according to the manufacturer’s listing. 

  • Intended as a direct bolt-on replacement of OEM exhaust manifolds — no custom fabrication required. 

  • Compatible with stock exhaust layout; ensure downstream exhaust and catalytic-converter configuration match expected manifold outputs.

Included

  • Complete pair of stainless-steel performance headers (left and right banks), including runners, merge collector, and head flanges.

  • High-flow, free-flowing catalytic converter integration to balance flow improvements and emissions compliance. 

  • Necessary exhaust gaskets and hardware for bolt-on installation — ready to replace the OEM manifolds.

Product Specs

  • Material: Mandrel-bent T304L stainless steel, thick-wall construction for strength and heat resistance. 

  • Header Design: Optimized runner geometry and merge collector for improved exhaust flow and scavenging efficiency.

  • Sound / Tone Character: More aggressive flat-six exhaust note — deeper, freer-flowing tone with improved presence under throttle and on overrun.

  • Fitment Range: Porsche 997 GT3 / GT3 RS (2006–2012)

  • Warranty: Covered under SOUL’s Lifetime Warranty for street or track use, for long-term confidence in use.

Product Features

  • Improved Throttle Response & Flow Efficiency — Free-flowing runners reduce exhaust back-pressure, letting the engine rev more freely and deliver crisper response, especially in the mid-range.

  • Race-Inspired Exhaust Tone with Street Usability — The upgraded headers unlock a richer, more aggressive exhaust voice, while keeping emissions-compliant catalytic converter integration for legality and practicality.

  • Durable, Track-Capable Construction — Stainless steel, billet CNC head flanges, and robust TIG welding ensure the system withstands high heat and repeated stress from aggressive driving or track sessions.

  • Bolt-On Installation — Designed to drop in place of OEM manifolds, using factory mounting points and exhaust routing — no cutting or fabrication required.

  • Balanced Build for Daily Use or Track Days — Because flow is optimized without removing catalytic converters, this header upgrade provides both performance benefits and everyday usability.

  • Solid Foundation for Future Performance Mods — By improving exhaust flow early in the system, these headers set the stage for further upgrades (e.g. mid-pipe, valved exhaust, tuning) — maximizing gains down the road.
