I cant decide what to do.... i bought the MBRP 5in turbo back straight pipe and tacked it together. My beds shot, just a matter of time before i get another. That being said, if i was to run stacks then now would need to be the time. I like to run two of the Cat stacks angled, figured i'd just move the tool box forward to accommodate the stacks. Any change expectations in performance? This is my first ford and first Diesel. Any tips are appreciated.
