I finally broke down and bought a new muffler. I've wanted to do something with the exhaust system since the day I bought it. But living in an apartment complex I decided to hold off (felt bad enough coming home at midnight with a turbo back straight piped 5.9 cummins for a couple of months) until I could finally get a new place. My fiance and I bought a place in the country, although we do have neighbors I'm not concerned about them.
On my 2015 6.4L hemi I installed the mufflex dd250035 kit. It had a great sound barely any drone. I did remove the resonator also. But wanted to try something different this time. It's not exactly easy to find a 3.5" inlet/outlet muffler, didn't want to step down to a 3", though about going up to a 4" and getting a dpf back kit but didn't want to drop $400+ right now on a exhaust system.
So after some YouTube video searching I decided to give the borla xr-1 40086 a shot. Since no one around here can bend 3.5" pipe that left me with a little problem. Since there is a offset from the inlet side to outlet side on the system I had to find someway of making this. After some pic comparing and photoshops I found some 42 degree bent sections. With a little cutting and welding I should be able to get them to work. 45's looked to be a little to much of a bend. With the muffler, 2- 42* bend pipes and a couple of band clamps to make all this removable It came to just under $250.
Everything should be here Tuesday and hopefully installed by Thursday at the latest, depending on how much of a fight the stock exhaust puts up. With about 3500 miles on my 2015 the exhaust put up a decent fight coming off. Can only imagine what 14300 is going to be like.
