Kline Innovation Performance Exhaust Headers for Porsche 991.2 Carrera (2017–2020)

Description

The Kline Innovation Manifold for the Porsche 991.2 Carrera and Carrera GTS (3.0 L twin-turbo) is a high-end upgrade designed to dramatically enhance both engine breathing and exhaust tone over the restrictive factory turbo manifolds. Engineered by Kline Innovation—an exhaust specialist known for boutique systems and exotic car applications—this manifold improves flow efficiency and weight savings through precision design and premium materials. It gives your 991.2 a more aggressive exhaust note, better spool characteristics, and a performance-oriented feel that matches the car’s spirited turbo potential.

Fitment Notes

• Designed specifically for Porsche 911 991.2 Carrera, T, S & Carrera GTS models with 3.0L twin-turbo engines (2017–2019 model years)

• Replaces OEM turbo manifold section and installs into factory locations

• Works with factory or aftermarket exhaust systems (requires proper flange alignment)

• Intended for performance upgrades—pair with high-flow cats, mid-pipes, and ECU tuning for best results

• Available in 304 Stainless Steel or premium Inconel 625 material options

Included

• Kline Innovation manifold assembly (single piece or bank set depending on configuration)

• Precision flanges and high-temperature welds

• Mounting hardware where applicable

• Installation guidance for direct fitment

Product Specs

• Materials: 304 Stainless Steel or Inconel 625 (Inconel is lighter, more heat-resistant aerospace-grade alloy)

• Designed for improved exhaust flow over factory manifold design

• Heat management and thin-wall construction for reduced weight and faster thermal response

• Fitment: Direct OEM locations for Porsche 991.2 Carrera

• Sold as manifold section (additional exhaust upgrades and cats sold separately)

Product Features

• Enhanced exhaust flow: Precision design helps reduce back-pressure and improve turbo spool response.

• Aggressive sound character: Frees up the turbo-charged 3.0 L flat-six to produce a deeper, richer exhaust tone.

• Premium material options: Inconel 625 delivers aerospace-type heat resistance, strength, and light weight, while 304 stainless offers strong durability and value.

• Weight reduction: Thin-wall construction reduces manifold and exhaust mass compared with stock components.

• Performance-ready design: Ideal base for pairing with high-flow cats, X-pipes, and performance ECU tuning to unlock full potential.

• Boutique fabrication: CNC precision and mandrel bending ensure consistent fitment and flow optimization over stock parts.
