Before I do something stupid here....

Don't be that guy.

What's down stream from there? Any filters or muffler?

This should be one of those moments in your life where you realize your being ridiculously lazy and you should take a moment and do what we all do. Take a deep breath say "ya, I'm not a lazy POS. I'm gonna do every job I do, right. This is the kind of shi#t I bitched about when I paid some lazy shitbag $130/hrs and he skipped doing it. Its time to pull the pipe apart. I won't regret it after the jobs done."

It's ridiculous because you worked so hard and diligently to do your project. Just so at the end you can half ass it by not taking 15 minutes more to swipe out the pipe.
