I want to lose my cats to make my exhaust louder and sound better. I have 2.5" true duals into magnaflow x-pipe into flowtech cutouts into 2 single chamber flowmaster mufflers with turndowns. It sound good but i just want it to be LOUD AND MEAN!! Can i get rid of my cats without throwing a check engine code or messing anything up? What would i need to do to make my truck run good without any codes or problems? let me know fellas! thanks!

 

you will either have to get 02 sims or a custom tune to turn off the ses trigger codes.

 

my tune shuts out the back O2's

 

quick fix, Bigger tips= louder exhaust
