OEM exhaust mod questions

So from what I understand there are 4 chambers in the exhaust each with a perforated pipe.

If you just want the exhaust to sound a little louder and a lot better, you replace the perforated pipe with a straight one in the INNER 2 chambers. If you want the exhaust to sound a lot louder, you replace the perforated pipe in all the chambers.

I just want to make sure everything is right.
