You'll be fine. Nothing to worry about.

you should be ok, thats as big as i would ever go though, the bigger the slower the gases escape and thats when you run into issues

i just took off my roush muffler and replaced it with a straight pipe. sounds much better but i went from 3in to 2.25.

I ran straight exhaust for a while. Didn't hurt anything,and was pretty loud.
