good job, i wanted to let you know i tried 3 downpipes. the best was Bosal! i went from holding 1.2 bar in first gear to 1.3-1.4 bar in first gear
i had to turn my mbc down a 1/4 turn. the down side is that it uses the stock third cat, which results in a cel. code 4020. a scoobysport cel fix took care of that. it's stainless and mirror polished(looks chrome). has a seperate dump for the wastegate.
