If your going to run it with oem cats you're going to be running around with the exhaust muzzled.

The pops and stuff on deceleration will be quieter IF kept on oem cats, But your defeating the whole purpose of the FI exhaust.

I tried changing the cats to test pipes once once, lets say that the bolts won and I buttoned her back up. It's not something I'm opposed too, just would have someone do it for me. Would I have to go with the FI HFC or really any? Lastly, how bad is the smell when the cats are not stock?

The stock Nissan catalytic converters are a bottle neck in the exhaust system and not going catless or installing high flow catalytic converters as our friend Trips stated you will be leaving whp/wtq on the table and restricting your exhaust flow and defeating the purpose of upgrading your exhaust system on your Z. The unburnt fuel smell/odor will be more noticeable going catless. After you install high flow catalytic converters you will notice only very slightly more at start up and driving your exhaust smell may seem a bit richer smelling. The Fast Intentions exhaust is definitely worth it if it is feasible for you to afford. There exhaust makes whp/wtq and they make excellent quality exhaust products and have great fitment also. The sound factor is really nice if you like the sound of their exhaust on your Z?

You may have to just settle for getting help and the right tools IF you want them installed.

From what I know a reputable shop may not want to legally touch them

As to the brand? FI and Berks are pretty much the most common and there's not a difference between the two.

The exhaust smell will not be noticeable on HFC's thats only an issue when running none resonated test pipes.

You'll notice a heck of a difference from oem cat's to HFC's

This is what I ran into. From what I was told they can get fines around $25K per instance. I had to end up installing them myself.
