Hello! I am an Italian boy, happy owner of a ford f150 lariat of 2004. engine 5.4 triton I have a rise of about 2.5 inches and tires 35 x 15.50 r20

 

Welcome to the F-150 forum! Glad to have you join us.

Have any fun performance modifications planned for the truck?

 

compared to European cars the performance of a 5.4 stock is fantastic. I want to modify the exhaust, but I do not know how to do it. if you take it from someone who removes the cat and writes a new map or remove them and mount a magnaflow or other, but I'm afraid of losing performance
