So finally I'm about to start my exhaust project. Finally got my tig welder. So it's going to start out stainless and then be finished into ti later this year. Just waiting on some metal to show up. But what I want to discuss is manifold length. These motors obviously respond to the longer manifold. 330mm I think is the termi wsbk system? Correct me if I'm wrong. Now would 360, 370, 380mm be better? Why?? Obviously the more recent akra wsbk system changed things. I already have a couple different lengths and designs drawn up. Please comment if you actually have knowledge on this. Thanks for the input!
