Overview

Porsche 981 GT4 / Boxster Spyder headers are one of the biggest single changes you can make to how the 3.8L flat-6 breathes. The SOUL Long Tube Street Headers replace the factory manifolds with smoother, larger runners and a better merge, so the engine pulls harder, responds faster and sounds more like a race motor.

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
Designed to avoid check engine lights

What is included

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

Specs

Material: T304L stainless steel
Measured gains: up to 30 hp (SOUL testing)
Manufacturer: SOUL Performance Products
Warranty: Lifetime, street and track use
