Hey guys, I have an 06 scab with a 4.6l and one of my cats is shattered and rattling. I want to delete the cats and use the simulators in a straight pipe istead of paying for expesive high flow ones.
I test drove an 11 Raptor 6.2l and it said I was using 17.9l per 100 kms of fuel with my foot in it. (Talk about fun). My 06 4.6l is using 18.9l per 100km on the highway. Would the shattered cat do this, and what else should I try? It has a K&N filter, throttle body spacer, Flowmaster 2 chamber muffler, Zmax and Mobile1 fully synthetic oil. I did put 35x12.5 Nitto Trail grapplers, which I know will hurt mileage, but c'mon 18.9l per 100km's
