The design on both systems makes it sound a little different. The N1 has the double canister mufflers versus the crossflow muffler Perrin has. I'd suggest listening to some youtube videos, and if possible, see if anyone local to you on these forums might have the exhaust for you to hear. Performance wise, catbacks don't matter too much.
