Dual exhaust?

    Is going to a true dual a good option, or is it better to keep it in the 2 into 1 (possibly back into 2) configuration? And what would be a good pipe diameter to go with? Keep in mind, I do not have aftermarket headers, YET, but plan on upgrading those later. I just have to replace the cat now and figured I may as well do the rest of the exhaust while I'm at it.

    I'm looking for a nice sound, better MPG for long trips and still have enough clearance to do some off roading.

    This is on a '94 1500 5.7L.

    If you're going with headers later, I'd scrap the cat and go with true duals, 2" ought to be right.

    just go with straight pipes do 2 1/2 in piping from headers back and do 3" tips at 90 degrees behind the tires and you will love it dont waste your money on mufflers its a waste
