These turbo dump pipes (also known as a downpipe) are made from sus304 stainless steel throughout and feature a single chamber design with increased bore for greater flow and more power. The flanges are 12mm thick so they will not bend or warp. Supplied with an EGO sensor port and plug as well as all gaskets and bolts. This will fit T25 and T28 turbos from CA18 and SR20 Nissans, however if you want to mate it up to the factory exhaust this is only possible on the CA18.
