PPE headers for 350 RWD (V6 2GR-FKS engines) for model years 2018 and newer (2016+ for GS models). These headers have a much larger cast inlet and 2.25” tubing with a 60mm outlet. These headers have SPORT high flow cats. Please call us if you have any questions about cats and emissions. Please note that RR Racing has not tested these headers. We are in the process of developing a tune for these headers. We expect that these headers would make 5-10whp over stock based on prior experience.
