Heres a technical one that i need solving....

Ive got a bpipe that im gonna put on, but the thing is, where it joins onto the axle back, it doesnt bottle neck down, But the axle back does, whats the reason as to it?

I was considering chopping the axle back and welding a straight 60mm pipe on so its a clean evenly flowing system, 60mm all the way

PS the axle back is Autotechinca Vision R n1 and the b pipe in question is 5 zigen
