I'm about to put a new exhaust on my truck but am not sure what to get. First off, I want it to exit the back at 45 degrees on each side. The exhaust is mostly for looks and I do not want to be able to hear it inside the cab if possible and would like to gain some hp or mpg if possible. Whats your thoughts what should I get and around how much will it cost? Any pics of exhaust exiting at 45 degree angles?

Edit: Wow I'm really sorry i posted that three times, I don't know what happened or why it did that.
