Some cowls have exhaust bulges at the bottom (Style 1) and some have a smooth bottom (Style 2). Did these come with the cowl from Vans? Are these added or removed by different builders as an option? Did Vans remove these from the design at some certain year, if so when? Just curious because I see less RV4s with Style 1, which leads me to believe they are the older kits.
Thanks!
P.S. These are random pictures I borrowed from google, so thank you if one of these RV4s are yours.
