Possible to swap out magnapack for magnaflow?

I have the magnapack catback on my 01 gt. I also have an o/r x pipe. NA the car was loud, but it wasn't upbearable. I actually liked it. I recently installed a P1SC...and for some reason my exhaust is a lot louder. I never thought I would say that my car was too loud for me.

Is it possible to just change out the magnapack mufflers for the regular magnaflows?

If not, anyone with a magnaflow catback wanna trade?
