i drive a 2008 f150 (5.4 liter). i want loud, smooth sounding exhaust tips. any suggestions

 

I had magnaflow exhaust tips on my si/do flowmaster exhaust. It was loud and had a very nice tone to it. I cut them off because they were uneven and one was starting to sag down a little bit and can't hardly even hear it in the cab now

 

how much is the tips and the flowmaster exhaust
