I am so sorry but after getting a new job I have been very busy. I'm glad you like the 14" as I too am impressed with the sound.

I have a 2011 super cab with a 3.7 with a FlowMaster 40 series and the resonator removed. every thing else is stock on the truck. It does get a little high pitched over 3500 rpm but when it is from take off to 2500 sounds really good for a v6. I did notice a little performance improvement. I know a v6 will never sound like a v8 but it does sound good to me and I am happy with it. At highway speed I do not get any drone from it. 70-75 mph and around 2000 to 2200 rpm. The drone goes away around 55 mph.
