6boost - Holden RB30ET SOHC Non Turbo Forward Position Pro Mod Exhaust Manifold
All 6Boost manifolds are individually hand made in Australia. They are specifically designed for your application and built around unique "merge collector" design. This means no pipes cross each other and the merge collector directs all exhaust gases at the turbine entry.
We have these to suit many combinations, if you don't see the combination you require in our selection please email and we can have one custom made for you.
Additional Extra's Available:
EGT (Exhaust Gas Temperature) Sensor Weldon's
