By removing the catalytic converter that is restrictive, it significantly reduces the back pressure compared to stock downpipe, with the 200 cell race cat, this provides more power, improved exhaust note and faster spool. Our downpipe features a full 4.5″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes.
