Description:

Improve high-RPM breathing on the Porsche 992 GT3 and GT3 RS with Valvetronic Designs EPA-compliant catted downpipes. Developed for the 4.0L naturally aspirated flat-six, the high-flow design reduces restriction while supporting the car’s motorsport-derived character and emissions-conscious requirements. The freer-flowing downpipes deliver a sharper, clearer exhaust note with stronger presence as engine speed rises. The result is enhanced high-RPM character without turning the naturally aspirated flat-six into an uncontrolled or overly harsh system.
