stainless or chrome stack?

That was one of my biggest concerns was the scratching, just put a set on a buddy of mines truck, he went with stainless. I told him he's got some polishing up to do to get em looking real good. They look good, but I told him to watch hitting trees or anything I was thinking they would scratch up alot more than the chrome would. I know Lincoln an dynaflex are more expensive but that's kinda where I'm leaning towards, thanks for that info largecar359. That pretty much summed up exactly what I was thinking about those stainless stacks.
