You may ask 'what's the point if the 3.0 inch downpipe tapers down to 2.75 inches'? Here are a couple reasons why the 3" downpipe improves performance:

  • The larger downpipe provide a greater area for the exhaust gases to expand - ie a greater pressure differential. The Turbo focuses the exhaust energy into the turbine to carry as much energy as possible. As the exhaust exits the turbo and expands, the energy dissipates so the goal is to have the largest area possible for the gas to expand - or a larger downpipe.
  • For the Downpipe with Catalytic Converter - the inlet and outlet for the cat on the stock unit is 2.75", the inlet and outlet on this unit is 3". The oversized inlet and outlet greatly improves flow with significant reduction in back pressure.

On any turbo, less backpressure equates to IMPROVED PERFORMANCE, less backpressure equates to MORE HORSEPOWER. The larger the turbo, the more critical this becomes. It may not sound like much, but when you run a larger turbo - it makes a BIG difference! For maximum performance, run the De-Cat Downpipe (or Cat-less dowmpipe).
