So, I don't know if all of you are a member as well of the Facebook groups, specifically the 2.8 LWN Duramax Owners. But a new member on there posted a video of his truck, tuned and deleted. Special thing about his is that he went with a 4 inch exhaust. Don't know if was a total straight pipe or had a performance muffler on there or what but I feel it was w/o a muffler.
Wish I could share the video but I don't think there is a way to share just a facebook video, as it will then direct you to the page and if you're not a member, I don't think you will be able to see it. But the truck sounded great. Had a lot better tone than any other truck I've heard so far. Guy said there is no drone while driving at highway speeds either.
He said he went with a Diamond Eye 4 inch down-pipe back exhaust. If you look on Diamond Eye's website, you will find they have no such exhaust for our trucks. I asked him about this, and he said that he customized an exhaust off of a 2nd Gen. Cummins from Diamond Eye to fit his Colorado. Not sure why he chose a 2nd Gen. Cummins though, not sure if they match the length of our trucks frame/ current exhaust system better and have a similar sized down-pipe (Ours is 2.5 inches I believe. 2005 Duramax's have a 3 inch for comparison) opening or what.
This is the 2nd person I have heard who customized a 4 inch exhaust from a bigger truck to fit our trucks. And they both sound great. I think I would consider trying this, as it didn't sound like any extra pipe bending was involved, you just had to do some trimming. Anyone else heard of people doing this and thought about doing it themselves?
