Got my pipes installed earlier this morning and
the sound is definitely noticeable. Especially around 3k. The smell isn't too bad, you can smell
gas but it is tolerable. As for the "cow crap" smell when I first got my pipes, I cleaned them very well inside and out so I don't think I'm going to experience anything like that. Hopefully I can stay under the radar with them and not suffocate the people behind me but at the end of the day I'm glad I did it.
And I made the right decision by having a shop do it. I got to watch Netflix while my car was given some sound. Gonna be a good day
