Tomei Full Cast Exhaust Manifold - BNR32 BCNR33 BNR34

All new, non welding one-piece structure made by full lost-wax casting ensures incredibly higher durability comparing to the old type which was weld-assembled structure made from pieces individually casted. Although lost-wax casting in one-piece structure makes the process much more difficult and time-consuming, the biggest benefit is that eliminates the well-know major problem of welded products, cracks at welding beads, even under severe usage. Another benefit of the one-piece structure is the smooth finish both in the ports and the beautiful appearance. Get this and all your JDM at RHDJapan!!
