their were 4 slots cut around the inside of the inside pipe around the diameter were the exhaust pipe goes in. I already have mine back on or I would take a picture. You can see them, their not far inside.

So its just a small round piece of exhaust tubing that will essentially close off the passages to the "reflective sound cancellation" area of the muffler ? This would essentially create a straight thru muffler right ? Very interesting idea.... Might be something to play with this winter

I am thinking about doing this maybe on my magnaflow setup because it is a bit quite for my taste.I hope the interior muffler design is similar....

I'm almost positive I did not have those. I wonder if I have an older system or something. Without the slots, i am sure the inserts would do nothing but restrict flow. Thanks for the info

Guys:
I was just told by Corsa, that adding these "inserts" will reduce the exhaust flow a bit. With my car being modified as it is, and dyno tuned to a specific Air Flow Ratio (AFR), I am choosing not to do this mod. If your car is not modified much this might be an idea to make the Touring a bit louder though
