Catted vs. Catless Invidia Downpipe
The Invidia divorced wastegate downpipes for the 2008 Subaru WRX are designed to replace the restrictive, OEM two piece downpipe that contains not one but two standard catalytic converters. Invidia made the 08 WRX downpipe from mandrel bent 3" stainless steel and welded on a thick flange and a cast stainless steel housing 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 reduce turbulence. This is optimal for stock and smaller sized turbo upgrades.

Invidia's catless downpipe will cause a Check Engine Light (CEL) on your WRX in response to removing the stock cat. 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. The high-flow catted Invidia WRX downpipe is not emissions legal, and may still cause a CEL in some cases. The high-flow catted downpipe also helps to reduce boost spike by adding back pressure to the turbo system.
