I've got a 92 with a 3.9 as well. I haven't done the air filter yet, but I
just replaced the factory exaust with a Walker perforance exaust (flow
through, bigger pipe etc.) BIG BIG improvement, and alot louder. Hills that
I regularly take I used to down shift on, now I don't have to. I noticed on
the old pipe that there was a spot that the pipe had been bent going around
the axle causing a constricted air flow spot. I couldn't tell if this was
bad design or just me smashing it into something and causing it to bend.
The angles looked intentional, but it was awfully rusty, so I couldn't
tell. And a bit louder... who cares, this is a truck, not a luxury car...
