You may ask 'what's the point if the 3.0 inch downpipe tapers down to 2.75 inches'? Here is the reason 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.

On any turbo, less backpressure equates to IMPROVED PERFORMANCE. 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).

  • 308 Stainless Steel
  • Made in the USA
  • Fits all US and non-US models
  • Fits OEM stock Exhaust

Available with our without the catalytic converter.
