I have been going back and forth between ordering a system or having one fabbed up custom. Well the exhaust shop I went to pissed me off so im going to be ordering a system now. Ive really only looked at the boosting performance system and the takeda by afe system. I really wish hks had single exit system for this car but seems dual is all that is available . Has anyone gone single exit on here yet? If so what system did you go with ? and any additional details would be appreciated. Also what downpipes do you guys recommend or have actually installed already. Thanks in advance !
