I have a s124 300tdt (om603), engine is original with adjusted diesel pump and turbo pressure. Is there more horse power to pick up if I build new exhaust in 3 "or are there other things I can do?

Aadjusted to max or with bigger elements? Either way, stock exhaust is kind of small, some bends get down to 2". You will gain some n/a torque as well as flow a bit better in high rpm but the more fuel you have the more you will notice it

Mine is 3" straight pipe from the second turbo all the way to the bumper. Works fine with my compounds, but I'll see if it needs upgraded when I upgrade my injection pump. Unfortunately due to the layout of my engine bay I can't fit larger than a 3" downpipe, and even that had to be oval pipe and requires a hammer to install

'77 300D, 617.912, HY35 15psi, 3" side pipe, maxed out stock MW pump (Sold, now converted into a ute)
'87 300TD, 603.960, questionable mods from the PO including a ghetto 3" straight pipe

Pump is orginal, no bigger elements..but i can probably adjust a little more on the pump, but not mutch.. i removed the catalyst and the last silencer, but i still feel the exhaust does not go out fast enough..
