Hi guys can you help talk me into removing my cat and Installing a MBRP cat delete pipe for my truck !! I want to hear all the benefits EGTs MPGs all the good info . I would just buy a complete system but here In Cali I have to smog my truck every 2 years so I have to be able to put the cat back in for smog inspections . I will also be having the muffler removed and a straight pipe put in its place . Im hoping with out the pipe being as big as the 5'' straight system I got rid of it wont be too obnoxious when I creep out of the hood at 4 am . lol
