Does this look right?

[Nima]

Hey guys agin;
I see lots of things under this truck which are new/strange to me. Well, maybe the reason is this is my first truck!. Anyways, while I was investigating under the truck I came cross right side exhaust tube which is rubbing agaist the frame, obviously that shouldn't be like that. Now I have two questions: 1- If I don't fix it right away, is this contact gona harm anything? 2- The area looks very tight, specially starter is very close to exhaust. I was debating when I change my exhaust, swithch my ram horn to headers but now, I am concern about space. Is this area suppose to be so tight?
