Bomiz Porsche 718 GT4RS/Spyder RS Titanium Valved Exhaust

The GT4RS carries the 4.0 flat-six from the GT3. The titanium exhaust builds on what Porsche started.

Porsche normally reserves the naturally-aspirated 4.0 flat-six for their track weapons. In the 718 GT4RS and Spyder RS, they put it in the 718 chassis — a smaller, lighter car built around the kind of driving the GT3 was made for. The Bomiz Full Titanium Valved Exhaust is built around that intent: titanium construction for weight reduction that matters at this level, Bomiz electronic valve control so you choose when the flat-six is at full voice, and a system tuned for the engine Porsche meant for this job.

Full titanium construction, hand welded and polished. Bomiz electronic valve controller and full wiring included.

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."
