I have them...I'm installing them this week finally (had them since december..lol).

What to expect? A little better midrange and a lot better up top. Make sure you get a decent header and exhaust setup. I'm using the JDM ITR 4-1, 2.5" carsound, 2.3" B-pipe and a spoon N1 rear section. Depends how you tune it and what you want out of it. Where do you want the power to be? Do you want midrange at sacrifice of high end or visa versa? ....etc.

I'm tuning with a VAFC and a chipped P28. All going in my b16a2 equipped 96 EX.
