My downpipe has broken at the flex section (The top part of the flex section that leads to the top flange that mounts to the elbow). My question is, is the diameter of the flex section the inlet and outlet 2.5" on both sides or 2.5" to 3"? I want to make sure i can find the right flex pipe so i can have a friend weld it in. I cant remove it off my car at the moment. So help would be much appreciated.

Won't matter as the flange and elbows are 2.5" Hell, might be worth is to go with a DP that replaces the elbow as well...

Removing the elbow is out of the question I don't have a ct26 and no one makes elbow/downpipe combo for a 20G. My question still stands though because the elbow outlet is only 2.5" or something like that.
