Exhaust Question

[1996MustangKid]

Hey two questions, 1 will the exhaust get louder as i get a new midpipe and headers? And 2 can i use the factory cat-back after getting BBK LT Headers and a Dr Gas X-Pipe? Or will i have to get a new cat-back? Also I know someone has a soundclip with the BBK Dr Gas Flowmaster combo can i possibly get a link to it?
Any help is appreciated, thanks

yeah it will be louder, especially when you get on the gas with the LTs and offroad pipe. And personally, Dr. Gas X with Flows is my favorite combo for GTs
