you have the evidence for your theory but why do our pcm give read outs for backpressure if nothing uses it.
egr still needs the back pressure
I also know that you dont want too big of exhaust bc it gives exhaust gases time to cool which cause them to flow slower because the gas becomes more dense. The deal is you need a compromise between sizes
