Why do you want to delete them? Make it louder? Installing the PE is easy enough to do in your garage or driveway I would just put it on, let it break in then decide if you want it louder. Plus trying to find a shop that will delete them is a challenge.
Unfortunately, I don't have the tools to install it in my garage. The reason of thinking about 2nd cats delete is that I read on here about the cats being too restrictive and hold up couple ponies. I am still not aware of how loud the PE is, since I can only hear it on youtube.
