Will removing the cat on your exhaust system make it louder? Im looking at a turbo back 4" exhaust system. I was just curious if this would make the truck loader going down the highway or would it just whistle more?

I have been doing a lot of searching on the site and I can't find what I am looking for. :dunno: If there is a thread on this please help point me in the right direction. I currently have a bone stock 96 f250. For my first mod I plan to do a cat delete. I am planning on ordering this delete...
