These bark boxes ?

I think the bottleneck would be more so the outlet on the plate itself. Having those flat square edges wouldn’t flow exhaust very naturally. But you have to consider, along with the stock outlet opened up that’s a fair sized additional port?
The deflector with the ramp is a pretty large, smooth flowing path if you ask me.
I don’t know and I’m just making assumptions here.
I do know that there is a bark box at a dyno right now along with a self modified front cover.

Alright, this may be a stupid question, but what the heck is a "bark box"?
