Time for upgrades
i've now had my '05 Ranger 4.0 FX4 LII for 7 months now and i am wanting to do some upgrading. my plans include: a intake system, exhaust, possibly a chip, and pulleys for now. My question is; is there anything i can do to the exhaust to increase performance without making it any louder?
Am i on the right track as far as good upgrades for this engine and how much mpg and hp will these mods do for me?
