What is a catback??
Alrigh, so me an a friend of mine are debating; what exactly a catback is. I tell him its mainly just bigger piping running straight from the engine headers to the muffler with no cats or other pieces in the way of airflow.
He claims its an actual manufactured upgrade of some sort.
Who's right???
