STM Downpipe / O2 Recirculated for OEM-Style Housing - Evo 7/8/9
Very great product, nicely weld, fit well under the hood.Good angle for O2 sensor. The car idle quieter now, engine run smoothly compare to my old leaking downpipe. But when it got boost OH MY... I wasn't prepared for that tone / sound, fantastic. Keep going STMTUNED

STM O2/Downpipe Recirculated for OEM-Style Housing
This is a no question buy. Why have a o2/downpipe when STM make this amazing combo less bolts and gasket's!! Cant wait till i pair it with a FP cast Mani and a Blouch Evo IV-IX Dominator 1.0XT Turbo (Journal Bearing) going for a 500whp sunday monster. Anyway this a top quality system with Amazing and Perfect welds! Proud to support a American company!
