HFC's will allow more flow too correct? how are HFC's different from test pipes? or are they the same pretty much?

HFC's are simply higher flowing catlytic converters. They won't flow quite as well as two plain hunks of pipe which is what test pipes are.

The difference is probably about 2 - 3% potnetial gain or about 4-6 whp between them. Possibly 1-2 whp more, but definitely not less.

The major difference is cost; HFC's tend to be quite a bit more expensive that TP's. Add more to the cost if you get resonated ones.

HFC's are more environment friendly, so that's plus (if that matters to you).

Both may result in CEL's (search for details why) and neither is a guarantee of passing an emissions test (not that this is an issue in FL).
