For those of you with 190d turbos only: does the flange between your front pipe and intermediate resonator have two or thee bolts? If it has two, is the front pipe straight thru, or does it have a Trapox? The flange was changed at some point, I'm trying to figure out why.

Three bolt flange(I have the one I took off my car available since I went with 2.5" v-band)

They had no need for cats as they burned much cleaner with inclined injector/prechamber arrangement
