you should check to find out if the 2.75 inch system is better than the 3 inch.
several guys have claimed the 2.75 is better plus have a free flow muffler fitted not a muffler delete.

They are wrong.
There is little to NO difference
Accept the price.
A D40 loves a 3" WITH a muffler each and every day of the week.

when you say freeflow muffler. are we talking a hotdog like this?

^ Yep. Anything with a perforated tube and packing vs a baffled/chambered muffler offers zero restriction. Just a matter of taste how loud you want to go - no muffler - hotdog - or something bigger.

yes the Hotdog type muffler / resonators are a little louder than the larger volume free flow mufflers [ round or oval ] if you can see through from one end to the other its a free flow , as Rabbid said no baffles etc.
tho having a baffle or chamber to make some tone makes for a much nicer sounding exhaust.

It doesnt take much to keep a turbo diesel quiet. I'v got a large offset 3" straight through, and its very civilised but authoritative. No droning, only really has a note when giving it a tickle before the turbo fully spools at low rpm.
FWIW, the mufflers on any exhaust onthe market will be a straight through.
Cant comment on how it will affect performance or anything else on a DFP vehicle though, sorry.
