The HSP S400 Single Kit Downpipe is constructed from 3.5'' aluminized steel and built to last. Each downpipe is built in quality fixtures to ensure proper fitment. This downpipe allows great fire wall clearance and can be made to work with the factory transmission dipstick tube, but our HSP dipstick tube will provide the necessary room for a simple install. This product is specified for HSP's S300 install kit, however, it may work with other aftermarket applications depending on pedestal height. HSP cannot guarantee proper fitment with other manufacturers components.
