I have a 2004 explorer eddie bourer 4.6 V8. i have removed the muffler, shortened the tailpipe. and i am getting the resonator takin' out in a couple of days. and putting a flowmaster tip on, what else could i do to get it louder? i dont want to spend alot of money on it. also, even after i removed the muffler my truck is quiet sorta while im at cruising speeds, will the resonator make it louder while im at cruising speeds?
