HKS FRONT PIPE FOR RX-7 FD

HKS Down Pipes are located in front of the catalyst and connect the catalyst with the manifold or turbo charger. Improving the diameter of the down pipes increases the amount of exhaust gasses that are able to pass through the system, and thus increases the performance of the vehicle. 

HKS downpipes are designed to increase exhaust gas flow and efficiency allowing quicker turbo spool up. All HKS downpipes are manufactured using the same mandrel bending process that is used in the manufacture of all HKS exhaust systems. Mandrel bending is used to ensure that the pipe diameter remains uniform throughout the entire length of the downpipe. HKS downpipes are designed to mount to factory turbo/extensions or to HKS turbo upgrade kits or extension kits.
