Frank, The idea was different

, before deciding on the v6 airbox, I found a viper evo having an airbox with 100 mm inlet and 100 mm outlet diameters. Pipercross evo is vastly different than the regular viper. After I see that I could not find that sort of reduction available in the market, I switched back to v6.
Yep I saw the one in Merlin but still does not work and I do not think we can fit a 76 mm to 70 mm without wrinkles occurring.
^^^^Thanks anyway for Merlin.
Alper why the 70 to 100mm ? V6 airbox is 70 to 70 ?
