Ricers install fart cans for the sound or performance whatever. It just so happens they are at the back of the car, end of the exhaust system. Tips are to slide over part of the actual end of the piping on mustang exhaust for a better look. Slash cut, rolled, whatever. A tip and a fart can are 2 totally different things. 3 inch piping on a 150hp motor is where your going to loose back pressure not with having larger tips on smaller diameter piping. That makes no difference in backpressure at all. Its at the end so the exhaust is leaving the pipes anyway.
