For sale, I have a set of GrimmSpeed modified stock headers. They have been ported, polished, and ceramic coated (black). They have also been professionally drilled/tapped for a 1/8" NPT exhaust gas temperature bung on the driver's side exhaust manifold button. The cast exhaust manifold end sections should fit any year WRX or STi. They were installed on my 2007 WRX for about 16,600 miles or 14 months, so there is some light surface rust from normal wear, but they are structurally sound (no leaks).
I also have two different crosspipes:
1. I have a GrimmSpeed high flow crosspipe which has been ceramic coated (black). It will only fit 2006 and 2007 WRXs because of the unique oil pan design (the angle of the bend is slightly different than other year WRXs). The GS crosspipe has also been installed on my 2007 WRX for about 16,600 miles or 14 months.
2. I also have a ported, polished, and ceramic coated (black) 06/07 stock crosspipe. It has not been installed since being modified. When I originally placed my order for the modified stock headers, I didn't realize that I had to specify whether or not I wanted the high flow crosspipe, so I was originally sent the modified stock crosspipe and I kept it as a backup.
Ideally, I'd like to sell everything together, but if you're only interested in some of the parts, we can work out a deal. All you really need is a fresh set of gaskets, although I'd also recommend getting some type of thermal wrap for them since they emitted enough heat to slightly melt my plastic undertray because I got rid of my stock exhaust manifold heat shields... nothing a dremel tool can't fix.
For prices, I'm thinking:
$250 shipped = cast end sections 06/07 GS crosspipe (as shown in picture)
