So today, i just cleaned and washed my truck and took it out for a quick dry off and i was behind a dodge ram 1500 with duals. Note my truck has Flowmaster 40's with 3 1/2 inch tips. 4.6L engine. But i rode past a few of my buddies and they said the quality of the fords engine sounds so much better than any truck they know of with my exhaust. FORDS RULE! But what do you think of Fram O2 BOOST air intakes?
