It looks great! Good job. As far as the smell, there are stickers and oil on several of the components to identify part numbers and prevent rust. That smell should go away.
Now for the clamp, I'm not sure how you got a 2" one on in place of a 2.25". Usually, they won't fit around the pipe. As far as tightening, just make sure nothing can move. Torque is done using a special tool called a torque wrench. Most people don't own one.
Let me know if there is anything I can do to help. Otherwise, great job.
Take care of yourself.
