I noticed the street pipe does not say full bolt on like the race and sport x pipes, instead it says it has a "flanged design for easy installation."

Does this mean there is some fabrication/welding required?
You cut your OEM xpipe behind the primary cats and slip the Street pipe on behind it. So, not a simple bolt on, but doesn’t require fabrication or welding either. Just cutting. In the first picture of the first post, you can see it next to the OEM pipe to get an idea of where its cut and slipped on.
