Tomei Full Cast Exhaust Manifold - Nissan RB26

Incredibly durable and reliable! Withstands extreme conditions.

All new, one-piece structure made by full lost-wax casting ensures incredibly high durability compared 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 extreme conditions. Another benefit of the one-piece structure is the smooth finish both in the ports and the appearence.

• Made of SUS304, full lost-wax casted structure
• Superior performance and exhaust note at all range
