Imprezer... did you notice any power increase after you got the manifold extrude honed?? A friend of mine has a Mustang Cobra and those guys have been basically dremeling and sanding down the inside of their manifolds to make them completely smooth (the inexpensive way, although $250 isn't bad)... they've been gaining like 5-8whp.

I wonder if doing this to the WRX manifold would give the same results. I've never actually looked inside one so I don't know if this would even be possible. I'm sure they're similar in the fact that they're both cast (?) and have some very rough edges internally. THANKS!

The TGV plates and shats were completely removed, welded shut and then the TGV's were gasget matched. That was before I knew I could just get the STi ones. Oh well.

Gains from all that? Not sure. I have lots more done so cannot say what that alone did. I am sure it helped. The car IS a bit harder to start in the morhing then before though.
