Question for y'all with headers. How much louder if any are the long tubes with regards to interior? Can you still talk to your backseat passengers or your wives? I've got a bad cat that needs replacing and am considering those Amazon headers like @badandyturbo put on his Tahoe but since this is our family cruiser, a quiet cabin is more important at this point than horsepower. Otherwise, I'm leaning heavily on replacing my Y-pipe and cats with the Magnaflow 51578. I can do this repair myself, the former I'd to have done for me and that is a factor too.
