Maybe it's just because I don't care much for sticking out, but I prefer to keep most things on a vehicle's appearance stock, the location of the exhaust being one of them. Would I put on a bigger exhaust? Yes. In a different location? No. I really don't care at all for stacks. It's not a big rig. But that's just my opinion.
It's also why I keep my truck at stock height. Don't care too much for the lifted truck with 37's look. Still running stock height with 235/85/16's on steelies with the factory hubcaps.
I do have a question though. Those of you who tow boats, what do you do to keep the soot off of the boat?
