718 GT4 Modular Headers
 

In this video, Fabspeed's Owner Joe Fabiani goes over how our RENNKRAFT headers for the 4.0l 718 cars allow you to swap between a catted setup for the street and a cat bypass setup for the track, all with one header.

In this video, we compare the sound of a stock 2020 718 Cayman GT4 to the same car with our RENNKRAFT™ Modular Street and Racing Headers in the street configuration with our HJS 200 Cell high flow catalytic converters. The car still has the stock GPF filters and PSE cat-back muffler in place. These headers are a bolt-on modification for the 2020+ 718 Boxster/Cayman GT4, Spyder, and GTS. Basically any Cayman or Boxster that gets the 4.0l motor. You will NOT get a Check Engine Light with these catted headers. Hear the car rev, drive-by under hard acceleration, and also hear what it sounds like outside and inside the car under normal driving and hard acceleration. We also compare with PSE on and off.
