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
This down pipe is great noticed a big difference with pull. Really good investment for the money skunk2 bolt up perfectly together. Nice sound. No problems
