SPA Turbo USA now offers a tight radius, 90 degree cast iron downpipe that helps a driver retain full use of accessories such as power steering and AC while removing the need for costly or sloppy fabrication. The downpipe inlet mates to any T3 turbine housings with a 4-bolt, 2.5” exducer outlet flange. The downpipe can be drilled and tapped for O2 or EGT sensors.
