ummmmmm.... have you ever looked into one?
Tip has nothing to do with it... an import performance muffler is just a straight pipe, with insulators all the way around it - but you can see straight through it, since there are no little sound barriers blocking or slowing down the air comming out.
When I look into my muffler, I just see straight through it, all the way to the part where it's attached to the catback.
