I have a pair of Prospeed high flow cats with about 300 miles on it.
It is custom made by Brian for fitment of NA1 header to NA2/LEV exhaust. I put my car back to stock after having problem passing smog (or finding someone to pass smog for me) and have decided to leave it that way.
So if you have a NA2/LEV and intend on using an aftermarket NA1 header such as GT-One or Fujitsubo, this is the way to go.
$350 shipped.
