just received my 60mm invidia test pipe for my ap1 this week. i haven't open the plastic bag it comes in, when notice i can see that pipe inside the pipe is not welded at the end.. that the best way i can describe it. I don't know if that how its supposed to look. the inside look kinda rusted ... here are some picture.
can any one verify that their is or is not like this..

 

So no one has any input.. Huh..

Pictures ???

 

If that's a picture of the inside of it, then that's fine.

 

sorry about picture.. they should be visible now

 

i thought the inside would be smooth for exhaust flow . and not have the lip

 

that's how 99% of pipes are welded, it doesn't take away from the flow

 

Perfectly normal. Exactly how my Invidia test pipe looks.
