Default will changing catbacks throw the tune off?

if so, by how much? specifically from a B & B to a hooker catback.

I wouldnt worry about it. The difference would be so little, it wouldnt matter.

Almost all cat backs flow the same, they just sound different. I wouldnt worry about your tune.

what about adding highflow cats? Not trying to hijack, I think it's relevant!

not unless you're going from straight pipes to a muffler.. even then.. that'd only cost a couple hp.
