Supercharged 5.4, true duals Questions
I have an 04 F150 5.4 3v with a whipple pushing stock 8 PSI. I want to run true dual exhaust with an X pipe and no mufflers ( like the sound), However can I keep the pipe size 2.5" for both pipes? Or is that to much pipe? Im keeping stock cats until I can get long tube headers.
