I don't know, I tried looking around for someone with this setup and apparently the ones that did do it are with cattless DPs

My experience with the Dinan FFE is that for a fact after adding highflow catted downpipes that exhaust got louder.

So for the PE more than likel it will get louder when adding even highflow catted downpipes

Here are some sample sound clips of the Dinan FFE with highflow catted downpipes





Next will have my mid catts deleted and will test that out for sounding before I jump to the Akrapovic SS to go with the highlfow catted downpipes

Since math is your example:
320bhp -15% = 272whp(335is)
398bhp -15% = 338whp(Dinan S3)

The net is 66whp more with a Dinan S3, wheel to wheel. 18WHP difference is incorrect.

You seem to make a lot of mistakes when Dinan is in the subject matter. What gives?
I wonder how the torque compares with what the stock offers (370 lb-ft @ 1500 rpm). What is the torque @1500 rpm on jb4, cobb and dinan?
