I’m about to order a JDL 3” Over pipe / Front pipe combo and have no clue on what flange I need to connect to the EVOlution flange.
JDL’s rear flange choices are:
3.0 flat flange
2.5 flat flange
2.5 OEM donut style
Please help, I’m getting different answers.

If the Evo3 flange is flat, get a flat flange. If the Evo3 is a 2.5" exhaust, get the 2.5" option. If it's a 3" exhaust, get the 3" option. If it's not OEM catback, you do not get the 2.5" OEM flange.
