[navara05]

Hey guys..

I know these topics are kind of repetitive but I surfed all 16 pages of threads and didnt get an answer.

I have an 05 Navara DX dual cab... Im definitely gettin 2.5" Mandrel Bent.

egr and all that other stuff is done and next is what chip to get for the zd30 its got 230000 kms just about what needs to happen

my question is.. what sort of dump pipe do i go for 2.5" or 3"

Cheers for your help

does anyone make a 2.5" dump pipe?
mine was a 3" but the outlet is more like a 2.75" and its fitted to 2.5" exhaust.

no real problems with it. but i have nothing to compare it against. it picked up power low down, boost comes on earlier. top end didn't change much at all (edit: thats for dump pipe only. 2.5" exhaust was already fitted.)
mind you my 2.5" exhaust has a full sized muffler as well as a resonator in stock position. its fairly quiet.
