SLS catless midpipe inner diameter

I had their catless midpipe. It lasted about 20K miles and it fell apart. Welds are terrible and it didn't fit very well. Was a 2.5" mid-pipe. As for the thickness, I don't not know. I would not buy from them again.
 
I have a catless 2.5" midpipe, I have no idea the brand but it's all stainless and it made a huge difference over the stock exhaust.
