Exhaust upgrade 120 1KDFTV

Gday everyone,
im getting quotes on a 3” exhaust upgrade to my 120. It’s a bit difficult to decide when every shop tells you their exhaust is the best choice! I’ve had quotes on a Manta / Reback / Legendex systems so far. Does anyone have any input on these brands, or some advice on alternatives they have used. I’m chasing a bit more power and torque when towing our camper, otherwise the cars still perfect!
cheers

I have a Roo Systems 3” which was made by Genie before they dreamed up Legendex. Works well but to be honest any 3” exhaust will do much the same job performance wise so look more at mounts etc as this is where they will fail off road. Also check out Scott’s Rods exhaust as an option. Had them do my street car . Mandrel bent & very well made at a good price. Hope this helps. Cheers Womble.

i tried a 3" on my 120 D4D manual
to be honest , i put it on , took it off, put it back on, took it back off, put it on again, and took it off again and sold it

it was droning ( at the rpm i drive at)
i didn't notice that much of a gain

i brought the misses a 150 D4D auto and i had some work don't and asked my dyno guy what differences he seen
he said don't bother he said it's a pity nobody just made the dump pipe , as the rest of the exhaust is great
if you NEED to do something , just change out the rear muffler to let it flow a bit more

i have had both of mine tweeked and they made a difference, but it's not just as easy as a flash tune , too many just tune 1 engine and use it in all others
that is not good enough
