I think most people actually drive like that deleted. I myself had a truck that was missing some parts and I did enjoy the extra power. The youngin's out there that buy one and make youtube videos blowing smoke everywhere ruin it for everyone!
Just like politics and religion, we all have our beliefs. Let's not let delete vs non-deletes be a new addition to that category.. it's almost like my oil is better than yours... :D
