Jay - When I installed my HTA Green I used the old style Buschur ported and coated stock O2 housing. I have an old Megan O2 housing sitting on the shelf, should I use that instead (2.5")? I thought the inside of the ported (Buschur) stock O2 housing looked better than the stock Megan, and that is why I chose to install the Buschur 02 stock housing. FWIW I just measured the hole on the inside of my Megan O2 housing (from wg side) and it appears to only be ~1.25". I have no idea how much air comes off the wg side, but the hole looks small and I was concerned it might cause boost creep.

Should I port the Megan and swap it out (over a stock ported) ? Thoughts / advice ? Thanks in advance...
