Is this MAC off road pipe that replaces the cat a slip fit?

If not, do I need to have it welded in or something, I hope not because I want to be able to put the cat in for inspection and I do not want to buy headers. Also what would I need to do with the O2 sensors? thanks!

 

anyone know?

 

Stock manifolds, cat and Y pipe? I picked up a RK Sport offroad pipe back in the day and had to weld a different flange onto mine.

 

Yeah it bolts right in where your cat would go. I guess you would have to plug in a O2 SIM when your not running the cat.

 

Yea I have the stock manifold, cat and y pipe. It looks as if the cat is welded onto the y pipe, can anyone clarify this?????
