I went with Flo-Pro they semm pretty good on price and it was a dual application for my truck. Easily went on and sounds pretty decent.

I love my Silverline... Picked it up from Wickeddiesels.com It's a 4" with flow-thru muffler.

I have owened 4 diffrent systems and to be honest FarmboysDiesel has a fantastic kit. Very affordable and the fit is perfect. I choose the 5" as it is not as loud as the 4". It is loud but is allot deaper in sound. I also opted for the 6" tip which adds that tone to it..

Love my MBRP, fit is great. Maganflow is a great kit, but pretty pricey. You'll probably want to go with the 5" if your modding the truck.
