A 2D CLR bend is normally considered adequate to not hurt performance and the sharper the bends the longer the straights and I think long straights are good for pulling a vacuum behind the exhaust pulses. However I don't have any data or links to sources to prove that or say conclusively what's best so I'm not going to argue about it...
