Need help! 335is guys or 335is muffler owners'

Hey guys,
I've been in the works of figuring out how to do a DIY BMW Performance exhaust under 300$! I think I have it down so far! But just curious on something with the iS muffler, has anyone looked/opened up one? Or can anyone do me a favor and look or put a bar inside the passenger side tail pipe to feel/see perforated holes in the piping!

How nice would it be for all of us to have a PE for under 300!
I should be all done with this project Saturday afternoon with pics and vid on how it is done! Ill be also offering a local service or more for people that want it done for a lowww price!
So basically im going to introduce the Ben exhaust mod lol
Thread will be up soonnmnn....

I remember reading the is muffler is the same as ours with different filling, so maybe just removing some packing materiel= is?
