I have just installed the tailpipes on my O-320. I was hoping that I could get some advise on what kind of clearance I should have between the tailpipes and the bottom of the fuselage. I have included a link that shows the clearance - about 3/8".
3/8" seems like it is close but in reality it works. Like everything else on the plane check it frequently during the first hours of operation bu I think you will find it is plenty. Well maybe not plenty but enough.
Looks about right. In your early flight hours, you'll likely have to tinker with it 'till it settles in. Early on, keep an eye on potential exhaust rub(contact) points, check the tightness of all of the clamps, flex joints, etc.

ditto. these have been hanging untouched for 500+ hrs. you can see a slight paint chip on the RHS above the exhaust. not sure how I got that. I put a small flare on the ends of the hanger rods that fit in to the hose and then clamped.
In looking at your picture, you need to rotate your pipes for more turndown, minimum of 25 degrees to bottom skin. Steve Melrons picture should give you a good reference as they are correct. Also the distance at the top is too close about 3/4 inch as they will tend to ride up at cruise.
