Good luck with your exhaust. I took all the DPF and cat and muffler off. I made an exhaust flange and put in a piece of 4" where i removed everything else. The exhaust temps are much lower and the sound is just a tiny bit louder. I really can't tell you if going 5" will help you or not. I know that my exhaust feels like it has a lot more air coming out of it now.
