Went ahead and installed the Banks 5" exhaust last night. Wow, what a difference in size from stock. Getting ready to pull the camper this weekend and really didn't want to melt anything. I swear, just driving around the block last night, I must have gained 50HP and 20 miles per gallon on fuel.
No, not really. Just seems like it has more power, but really cannot tell. I don't drive full throttle most days.
I did have a little issue with the tube in the stock. Had to work it with PB Blaster, loosen it, tighten it, spray, until it came out. May end up ordering that tube to replace it.
2017 CC SRW Midnight Edition - Love the new truck.
