Aftermarket exhaust will always increase your mpg as long as you keep your foot out of it and drive like a maw-maw. Which won't happen, at least not until the new wears off. You will accelerate harder and stay in it longer just listenin' to the rumble.
As for "Slo"master, you will lose some low end torque due to the baffles they use for their sound. Magnaflow, Borla, Bassani, all have straight thru designs actually increasing low end torque. I recommend Magnaflow for a balance in sound, performance and price.
