Best "bang for buck" headers and remainder of exhaust system for 95 4x4 auto 3.0?

Thanks, Dave

Pacetter headers will be fine and cheap. as for the rest of the exhaust, thats personal preference. go to a exhaust shop and get what sounds the best to you.

Here's a link for the headers.

I have installed headers before on other vehicles and realize they are a pain.

How rough is installation on V-6, 1995 Pathfinder with auto trns?

The only hard parts is there's almost no roam to work. Usually with the 3.0 you'll have a few broken studs which can be a pain to remove and replace.

easier with a body lift.

broken studs are prolly the worst of it.
I run a 2.25" magnaflow cat & mufler I ran 2" pipe after the mufler to reduce backfire from lack of preassure. I liked it better after reducing it.

IMO larger than 2" pipe on vg30 w/ headders robbs you of low end tq

as far as efficiancy, I now get 20mpg on the higway and it used to never do better than 17
