The long exhaust piece. It flattens out and is very restrictive. Header + exhaust is kinda dumb if you don't put in a straight pipe here. Just doesn't make sense.. when my Greddy exhaust comes it'll be:
Down pipe -> straight pipe with after market cat, 2 bungs for wideband and o2 sensor and then the cat back greddy exhaust.
