I am looking at changing my exhaust before I get my car back from forging but what exhaust will be best suited for my setup. Fully forged 4e Billet wheel td04 hybrid (WEPR) + supporting mods Once finished I am hoping for around 300hp but want to get a decent exhaust system. What diameter? What brand does everyone recommend? I don't want to spend through the roof so bare that in mind when replying. Thanks in advance.
