I just received my 20" exhaust from Dirty Deeds today. I was not completely happy with how loud the 16" was. I have to say my wife liked it, I was the one who wanted something a little quieter. The 16" sounded great, and if I didn't use the truck as the family vehicle I probably would have kept it.
After calling Keith, I was able to have a new 20" shipped to me and set up the return postage on my old 16". In all, cost me $260 to do the swap.
I just swapped it out and there is definitely difference with the 4"(that's what she said). It is quieter in all aspects, but better then stock. Under full throttle, has a great note. Just like the 16".
I mounted the tip just a little lower then the first time. The original mounting liked like it was almost facing upwards and I was afraid rain would run into the pipe while it was sitting.
