Not to stray from the topic too much today but I saw an early 90's 190 (single overhead cam engine) with a straight pipe from the end of the down pipes past the rear bumper. The new pipe was actually a section of a backyard swingset leg. Car had been owned by a local redneck
. Unfortunately, the car needed a fuel pump and I was unable to hear it run. The guy said it sounded very rice
. He did have the prerequsite fart can at the end. It was actually a pretty neat looking installation - I wish I had had my camera.
