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. ?

The previous one was the passenger side tip, this is the drivers side. Slight better but still smaller diamater. Also I notice a tiny tiny tiny whole in one of the welds. About a hair thin

No, it won't affect performance; too far down stream.

Do you know what type of material the smaller pipe is made of. If it's regular steel you can potentially have rusting issues down the road.

Also, looks as if he just tack welded the tips on.

ok! good to know lol. Tone does soud a bit more refined now. And he used regular steel pipes but he coated them with enamel anti rust spray. Tack welded?

Just realized you're in Miami so rust may not be much of an issue where you're at.

Tack weld means the pipe is not welded all the way around rather in spots just to hold the piece in place.

Haha well it is very humid over here during the summer. Im guessing tack welds are ok?

the nismo tips seem to be resonated. The exhaust sounds deeper now.
