The A'PEXi Down Pipe is the pipe on turbo vehicles that connects the
turbine exhaust housing to the catalytic converter. Although short in
length, the A'PEXi downpipes provide incredible amounts of power because
the piping diameter is enlarged so early on the exhaust system. This
enlargement in diameter results in a dramatic increase in exhaust flow
capacity as well as a significant reduction of back pressure. The GT
spec Down Pipes are constructed of fully polished SUS 304 stainless
steel.
