These turbo's are manufactured from ALL new 2010 specification exhaust & compressor designs. They also include new competition actuator capsuels. They are a direct replacement for the original unit. That means the exhaust manifold flange is original and therefore no bespoke manifold required. The original exhaust front pipe connection is the same so your own exhaust system will fit. Induction can be original or upto 76mm as requested.
