Bomiz Porsche 991 GT3 GT3RS Headers

The 991 GT3's flat-six breathes through the headers. Open up the path and everything downstream changes.

Porsche's 991 GT3 was built around a naturally-aspirated 3.8 flat-six that rewards the full rev range with increasing character and precision response. The Bomiz headers open the exhaust path at the source — where restriction costs the most. Precision fit for the GT3 and GT3RS chassis, low restriction design, and built to work with any catback system you run downstream. If you're building a proper GT3 exhaust setup, this is where it starts.

T304 stainless steel, hand welded and polished. Direct fit for 2014–2019 GT3 and GT3RS.

WARNING: Please note that certain aftermarket exhaust systems may not comply with applicable US (including California) laws and regulations, and may therefore be prohibited for use on highways or roads, or on roads or vehicles otherwise subject to emissions control requirements. California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system.

BOMIZ parts or exhaust systems/components used or intended for use on "racing vehicles" (i.e. a competition vehicle used exclusively for competition on closed-course circuits) do not require an exemption or Executive Order from CARB to be sold in California. However, such parts are prohibited from use on California public highways or roads, even if occasionally used "off-road."
