Anyone notice a MPG increase with replacing stock muffler?
Thinking about getting a flowmaster or magnaflow to replace the stock muffler. I am not doing this for an increase in gas mileage mainly for the sound. On the 4.6 has anyone noticed an increase? what muffler do you have?

I had the stock replaced by a Magnaflow. There is definitely a noticable power and torque increase which was nice. As for MPG I was averaging 15.3/15.4 rural city driving before the muffler and it seems to be very consistant at 15.5/15.6 so there was a slight better MPG. I suspect on freeway driving I'll show even a better MPG gain. In any case it's still good to go, nice to have a little extra punch and I made my engine happy:
