Ram Tube Option

[wild_70]

Hey all, im looking at trying Ram Tubes or velocity stacks as some people call them on my 2tg next race. But theres a few different styles... im just wanting your opinion on what you think the best option is. It's only bitumen work so i dont plan on running filters either. Cheers

the first pair is supposed to be the best as there is much less turbulence around the bell mouth, where are the last pair there is a lot of turbulence on the underside and around the lip of the bell mouth.

as above, those middle ones if they have the internal shape that I think they do are an abomination, not even a proper ram tube internally
