GrimmSpeed Downpipe 3" Catted LIMITED w/ Black Ceramic Coating - 2002-2007 WRX, 2004-2007 STI, 2004-2008 FXT

Grimmspeed fabricated some of the highest sought after modifications due to their respectable build quality standards. This is their 3" Limited Downpipe that features a CNC machined turbo outlet flange which promotes better wastegate flow, along with better boost control. 

For those of you equipped with a wideband O2 sensor, there is a provision at the top of the downpipe for your sensor attachment, and it has a factory mounting provision welded on the side of the pipe so that it bolts on just like stock. Moving down, you will find a high-flow cat converter which is emissions friendly while still being able to produce lots of power which is the purpose of downpipes. Behind the catalytic converter is your factory O2 provision and finally the downpipe ends with a 3" flange.

This downpipe has been fabricated from top quality stainless steel, and is ceramic coated black for heat protection, as well as protection against corrosion. 

Brand new gaskets, as well as hardware, will be provided with the downpipe to make for a ready installation.
