Invidia Catless Divorced Waste Gate Downpipe 2008-09 Subaru WRX/STi
The Invidia catless, divorced wastegate downpipe for the 2008-09 Subaru WRX/STi is designed to replace the restrictive, OEM two piece, two cat, downpipe. Invidia made the 08-09 WRX/STi downpipe from mandrel bent 3" stainless steel and welded on a thick flange and a cast stainless steel housnig to provide maximum airflow and improved performance. A divorced wastegate downpipe has a plate the protrudes into the turbo to separate exhaust flow coming out of the turbo to give reduce turbulence. This is good for stock and smaller turbochargers.
NOTE:Invidia's catless downpipe will cause a Check Engine Light (CEL) on your WRX. While this isn't harmful, it can be annoying and disables the cruise control -- you can use a software solution such as the Cobb AccessPORT to eliminate these codes or try a mechanical fix (O2 sensor spacer). Boost spiking may also be a factor, which can be controlled with devices like the Cobb AccessPORT.
