Made and designed by legendary Japanese tuning shop Tomei
All-new, non-welding one-piece structure made by full lost-wax casting ensures incredibly higher durability compared to the old type which was a weld-assembled structure made from pieces individually cast.
Although lost-wax casting in a one-piece structure makes the process much more difficult and time-consuming, the biggest benefit is that eliminates the well-known 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.
