Anyone know where to find this type of duct hose? Looked through home depot and rona and not the same type. Ones from hardware stores are quite large in diameter, plus the inside is quite "rough" instead of a smooth transition. Project is for an extra ram air into the airbox (here's a link of what i'm trying to achieve

Currently, am using the flexible hosing from rona but want one that is smooth internally. Max diameter that I'm looking for is 2". Any ideas?
