I went with an Aero Turbine in place of the stocker and kept the resonator. I picked up some performance and mpg and it has a really low rumble that sounds great but is not overly loud.

 

I JUST, like yesterday, put a FM 40 on my truck, single 3" in and a single 3" out. I just cut out the muffler and put in a 24" piece of new pipe before the muffler. Then I cut another peice of 14 or 16" new pipe and connected it to the old tail pipe. Welded on my tip. I did it in about 2 hours and cost me $150.00. It is louder then what i was going for, and just a little noisy in the cab with a slight excelleration. When i really hit it, its not as loud and sounds good from the cab. But overall, i am happy. Biggest thing will be adjusting to the change of sound.

thanks for everyones help, i have pretty much decided to go with a FM 40, dual with 3" out. all welded with 4 in tips welded on, 500. sounds decent to me
