Need input, does this look like it will affect exhaust flow?

Hey guys. Basically what I asked in the title. I have a top speed pro 1 cat back exhaust true dual. I cut off the tips from my Nismo exhaust to have them put on my current set up. Looks awesome but It the Nismo tips had to be welded to the mufflers at at an ange and the mechanic Bent the pipe a bit awkwardly as you can see in the pics. also I beleiveed he used a smaller diamter pipe. About .25 Inch smaller. Will this affect my Performance. ?
