5 inch on an '03
JTeague,
We had one in here last week with a 5 inch, the customer was wanting to trade us for our 4 inch 304 stainless system. He didn't like the sound or the voulme it produced. We aren't into trading etc but he got one of ours anyway and we helped him put it on and he left with a more of the familiar 24 vavle sound and reduced overall noise levels. The 5 inch sounded kind of hollow and scratchy, probably not the best description but I'm no Hemingway either.
