Also Carlos - the plenum is FULLY POLISHED - not just down slightly beyond the powder coat. I spoke to a lot of folks with chromed and/or fully polished plenums and I had a look at plenty and I have to tell you that those baby's get real dirty/cloudy/mucky real quick and they are really hard to clean/re-polish down in the centre section especially. So I painted it out.
I am not a fan of chromed plenums - I believe the chrome will eventually flake off or turn bluish.
