Overview

Factory manifolds on the Porsche 991 GT3 / GT3 RS / 911 R are built around emissions and cost. The SOUL Competition Headers are built around flow: equal attention to runner shape, merge and flange fit, for sharper throttle response and a louder, cleaner 3.8L / 4.0L flat-6 / 4.0L flat-6 note.

SOUL Performance Products is a Pennsylvania exhaust specialist known for in-house engineering, careful fabrication and parts that are developed on real cars. Parts are covered by a lifetime warranty for street and track use.

Features

Optimized runner diameter and length for flow and response
Machined flanges for a leak-free seal at the heads
Smooth mandrel-bent tubing and a high-flow merge collector
Billet CNC-machined parts where strength and precision matter

What is included

Headers (left and right) with the hardware SOUL supplies for installation.
