I may want that buddy club spec IV catback. can you verify that it is full 3" piping with NO restriction at the flange? also since it is JDM do I need a JDM downpipe? I'm looking to buy a downpipe as well and I need it to have an extra bung for a wideband O2 (like a titek DP has).
let me know, I sold my turboback last sunday and my sti want a new exhaust.
