Fabspeed Sport Exhaust Headers for Porsche 991 Carrera (2012–2016)

Description

The Fabspeed 991 Carrera Sport Headers replace the restrictive OEM exhaust manifolds and catalytic converters with a high‑flow, performance‑tuned header system — drastically improving exhaust flow, boosting torque especially at lower RPMs, and giving your 991 a deeper, more aggressive sports‑car voice. With smooth mandrel‑bent stainless runners and integrated high‑flow cats, this upgrade sharpens throttle response and brings a stronger surge through the powerband without sacrificing street usability. It’s an ideal first step for Carrera owners seeking real power gains and a more visceral exhaust note while retaining catalytic compliance.

Fitment Notes

• Compatible with Porsche 991 Carrera models built between 2012 – 2016. 

• 2012 is a split model year — verify that your 2012 Carrera is indeed 991 chassis (not 997.2) before ordering.

• Intended for cars originally equipped with standard exhaust (non‑center‑lock wheels) and OEM exhaust layout.

Included

• Full set of performance headers (left and right bank), constructed from T304L stainless steel mandrel‑bent tubing. 

• High‑flow catalytic converters (200‑cell HJS sport cats) — integrated to preserve emissions compliance and avoid check‑engine lights when properly installed. 

• Multi‑layer exhaust manifold gaskets for a leak‑free installation.

• All necessary hardware and flanges for bolt‑on installation, using existing exhaust mounting points.

Product Specs

• Material: T304L stainless steel, 14–16 gauge, mandrel‑bent for smooth exhaust flow and durability. Header Design: 3‑into‑1 merge collector with investment‑cast high‑velocity 3‑1 collector for optimal scavenging and flow. 

• Flow / Catalysis: Includes German‑imported 200‑cell HJS high‑flow sport catalytic converters — flow rated at ~93‑95% of straight‑pipe equivalent (typical for HJS cats) per manufacturer specification. 

• Performance Gains (rear‑wheel measured): +15 whp and +27 ft‑lb torque at ~3000 RPM across the mid‑range; mild peak gains (≈ +5 whp, +9 ft‑lb) at higher RPMs. 

• Fitment Range: Porsche 991 Carrera (2012–2016) (verify chassis for 2012).

Product Features

• Noticeable Mid‑Range Torque & Throttle Response Gain — The smooth 3‑1 merge design and improved exhaust flow dramatically improve torque and throttle response, especially off the line and under part‑throttle conditions.

• Aggressive yet Refined Exhaust Tone — The sport‑headers unshackle the flat‑six’s exhaust note, giving a deeper, throaty growl and more prominent exhaust character while keeping emissions‑compliance thanks to the integrated sport cats.

• Bolt‑On Direct Fitment — Designed to bolt directly in place of factory headers using existing mounts and flanges, minimizing installation complexity and avoiding modifications.

• Durable, High‑Quality Construction — Built from premium stainless steel with thick mandrel‑bent runners and robust merge‑collector casting for durability under heat and repeated stress (street or track).

• Balanced for Street & Performance Use — Because of the included high‑flow cats and thoughtful engineering, the system avoids aggressive “race‑only” harshness — making it suitable for daily driving or spirited weekend runs.

• Lifetime Warranty from Manufacturer — Backed by the manufacturer’s warranty, giving buyers confidence in longevity and build quality
