For sale i have a complete header coming off a 2006 STI. The ends are ported with a Grimmspeed coated crosspipe. Grimmspeed gaskets are used for the crosspipe too. Only 7k miles on the GS pipe, with the flex joint having zero leaks or defects. No defects such as cracks, dents, leaks, etc on the mNifold ends either. I guess we can start the bidding at $200 shipped.
