Fabspeed 991.2 GT3 Sport Headers with HJS Cats

Fabspeed 991.2 GT3 Sport Headers with HJS Cats: sport headers with HJS 200-cell high-flow catalytic converters that replace the factory headers, for the 2018-2019 Porsche 991.2 GT3 / GT3 RS.

Why HJS

Fabspeed imports its HJS catalytic converters directly from HJS in Germany. The high cell-count design keeps enough catalyst to avoid a check engine light while opening up exhaust flow and sound.

What's Included

• Fabspeed 991.2 GT3 Sport Headers (HJS 200-cell cats fitted)

Features

• Sport headers with German-made HJS EMITEC 200-cell catalytic converters
• HJS converters flow up to 90-93% of a straight pipe in most applications, per Fabspeed
• Designed to run with no catalyst check engine light on a healthy engine
• Tri-metallic OBD2 catalyst construction
• Fabspeed Lifetime Warranty

Fitment note

Fits the 991.2 GT3 and GT3 Touring (2018-2019) and GT3 RS (2019) as sold in the US. The 991.2 GT3 was not sold in the US as a 2017 model.

Emissions and use

The HJS sport catalytic converters keep catalytic function, but Fabspeed lists them as not CARB or EPA certified, so this part is sold for closed-course and off-road use. Check your state and local emissions rules before you buy.

Not CARB or EPA certified; closed-course use.
