03 wrx downpipe question
i have an 03 wrx with an espelir cat back system. Ive looked at some diagrams of the exhaust system, mot of the show turbo back being made up of the downpipe, a midpipe, then the catback section. I want a full TBE system so i can move to stage 2. will an aftermarket downpipe also cover the section labeled as "midpipe" or do i need to purchase a midpipe as well? most of what im reading shows i should only need a downpipe to complete the TBE but i want to be sure its right before i order the stage 2 AP. i know this is a newbie question and im pretty sure i already know the answer (downpipe is all ill need),so im just looking for clarification on this. thanks!
