RBC is the intake manifold off the JDM CL7R and the USDM Civic Si. It replaces the RBB's long thing runner with short fat ones to get as much air in the cylinder as possible, which makes it more suited to high rpm and VTEC when air flow is at it's highest JDMyard sell them if you pre-order for I think $550.

The headers and cat went on today, tonight I'll post up the pictures and write up my thoughts etc. Thanks for all the comments etc. I hope to write a lot more in this thread that might help people
