https://www.youtube.com/watch?v=zK643x41t4g&feature=youtu.be Sorry. I thought I uploaded a video via my phone, but apparently it did not work. I went ahead and uploaded the video to Youtube (I also put the link in the original message).

Let me start off by saying I am not very knowledgeable when it comes to vehicles. I purchased a 2014 Silverado z71 crew cab hoping for a reliable truck that would last me well beyond when I pay it off. I figured I would come to this site to ask people that are much more knowledgeable than I about an issue I am having. I own a 2014 Chevy Silverado 5.3 with after market exhaust. The exhaust was put on the truck by a previous owner. At idle, the truck seems loud (and not from the exhaust) standing on the side of the truck by the front doors. I am not sure "ticking" is the right word, but that's about all I can come up with. I have heard some people talk about the DI causing this, but my brother also has a 5.3 and mine is way louder than his. It is almost embarrassing how loud it is when people are standing around it at idle because they are constantly pointing it out. My question is: Is this the direct injection, or could I possibly have another issue (such as an exhaust leak)? I have attached a video for anyone that has the time to listen and provide feedback. A big thank you to anyone that takes the time to provide feedback. I am looking forward to checking out this website in the future and increasing my "truck smarts." Thanks again. Here is a link to the video of my truck: https://www.youtube.com/watch?v=zK643x41t4g&feature=youtu.be
