Which upgrades are most effective on explorers?

IMO 95+ stock MAS' are large enough unless you have substantial power mods. Some people report gains with aftermarket ones, but many people also report no change except a lightening of the wallet.

91-94s however, will benefit from a larger MAS if they have other intake and exhaust mods.

Dual exhaust system

I would like to install a dual exhaust pipe system to my 95 X? I am planning to install a flowmaster as well. I would like to gain some extra horsepower hopefully better mileage and of course the nice rumble sound of a V8. I have the V6 as you might have guessed. I also have 120k miles on the motor which is in ver good condition. Any suggestions on this upgrade guys. thanks for you help
