Performance gain from swapping o2 housings

[DSMSpyder99]

I have a ported 2g o2 housing and i just saw that Punishment Racing is selling a 2.5" tubular o2 housing for $130 w/ a lifetime warranty. So i want to know would i notice a performance gain from going from a ported o2 housing to a tubular o2 housing? Anyone with first hand experience would be greatly appreciated.

This probably wont help you a lot but my brother went from a factory O2 on his 92 trapping 109mph consistantly to a tubular O2 with dump and trapped high 112's consistantly.
