Downside of aftermarket exhaust.

Good morning y'all!

So I'm thinking about swapping out stock exhaust for an aftermarket one. I'm curious what the cons of them as if It will damage the engine or If I need to switch out anything such as high flow air filter to accommodate the set up. Please advise if y'all have ideas or experiences with these mods. Thanks!!

 

Welcome from the center of the bourbon universe. Can't help with the exhaust. Mine's stock.
