hey guys i have a 87 f150 4.6 liter v8. i took off my muffler and replaced it with normal pipe. ive heard alot of different things about what it can do to your valves and motor in general. i still have my 4 cats and i love the sound of it but i would like to know if its gonna hurt the truck or the mileage i get. thanks for the help!!

As long as you have your cats you should be fine.

Won't hurt a thing! You
May even see a increase in mpg if you can keep your foot out of it with your new found sound! Lol
