Introducing the RV6® cast stainless precat deletes and high flow precats for the 08+ J-series V6 engines. These castings will be used to make precat deletes and high flow precats (HFPCs®) They were designed completely using 3D CAD and CMM. The transition from flange to pipe or high flow cat is made from precision casted 304 stainless steel. This allows for optimum turbulence free flow with no sacrifice in strength. The castings are no thinner then 5mm at their thinnest point, roughly 3 times thicker then the prototype and previous PCDs®. We are confident that these castings can handle any abuse without cracking.
