4.0 v6 Increase Performance?

I have a 98 Ranger with 4.0 v6 and an automatic


It has 108K right now


I would like to increase its performance as it seems to struggle going up long hills at over 70 mph


This truck is 4wd extended cab and bone stock.


What are my options?

I've heard a good cat back exhaust (the factory pipe between the cat and muffler is a whole 2" diameter) and a better flowing air filter make a nice difference.


Beyond that I don't know, I'm new to these trucks myself.

I have a 94 SC 2wd man trans. Installed a free flow air kit and a 2 inch Y back exhaust with free flow magna flow muffler and new cat. Truck sounds better and is a little more responsive. The air flter was from a AM site cant remember name but was for a 97. The shop for the exhaust was an independent and he made the new Y connector and made the system as straight and bend free as he could. No it was not a fancy system made with a standard bender. Currently has 320000 on it and runs great, passes annual emissions no problems. As far as I know there are not any real AM performance kits available. Just keep tuned makes a big difference.

Did you keep your cats with the new Y pipe?

I had hi flo cats installed. We have emissions testing here. But it is a free flow muffler and the minimized bends that are what required. He used a standard bender but did not over bend to cause the creases and kept everything as straight as possible.
