I know there are like 3 or 4? converters on the exhaust system on the 99 4.6 f-150, my question is how many if any can you take off for a clearer, louder sounding exhaust note. Will it effect drivability or will it just spark off the MIL code like the mustangs? Are there any MIL eliminators you can install like the stangs? I just want the truck to sound louder and clearer just like when you put on a offroad pipe on a mustang. thanks for any input.

 

yeh mil eliminators off stangs will work on any fordvehicle. there are 4 cats total 2 pre's they just have a few screens on them their mostly for size transition to the smaller exhaust pipe and to make the bend. the only true cars are the two right below the front seats. u can remove them but u will have problems passing inspection. unless theirs sniffers used in ur area for inspection i'd suggerst piping through the cats or just gutting them out. so that they will pass the visual inspection
