A'PEX Down Pipes replace the factory downpipe and catalytic converter and significantly improve exhaust flow. Stainless steel flex joints are used to dampen the cat-back exhaust system from engine vibrations. A'PEX Down Pipes are available in two different grades. N-1 are manufactured using aluminized steel and treated with high-temperature titanium particle coating. GT are constructed entirely of SUS 304 stainless steel. |

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.
