T4 exhaust ports

[njv]

hi
i have not one bit of proof to back up the fact that sqr ports flow more im only going on what ive read on the net wally even jake says its true these days and well remmele uses the sqrs and so do most other german tuners dont they all that initially set me off that they must flow more is just the x-section compared to oval ports they have more!

sorry if im a disapointment in my lack of proof but its obvious or?
