Brand new exhaust and tail pipe. The muffler I was told is a "turbo tube" not sure the brand but it sounds great. It's mostly quiet with a great exhaust note and it sounds the way it should stock so. Also checked the trans and transfer fluid and was about 2 3/4 quarts low in the transmission and a 1/4 in the tcase. I have already resealed them both and they still leak. Also changed the engine oil for some new 15w40 Rotella
