i put a 4 in flowmaster muffler on my truck last night to keep it quiet because i leave the house for work at 3 or so in the morning :kick:
would the back presure make the truck run better it seems to be quicker(more low end) and i run like 25 to 27 psi where i normally run like 22 to 24 or is it just the cold air
thanks
