  1. I ordered this kit with wanting to kick the exhaust out the side and having a traditional tip. The PPE tip is 5" and oval'd - it looks great !!! Will be a black tip once they become available - Thanks to Hill Diesel ! Anyway, I had some snags, it was a huge pain getting the exhaust out but so worth it ! Hope this helps someone that is on the fence. It's a small increase in sound, mostly just deeper. I love it, though ! Looks great !
  2. I'm not sure if it will 100% work, but i'm not sure i could get the individual parts anyways. Long story short, I'm in california and most places wont sell the S&B cold air intake. even if i got it completely, it's not carb legal (i need the sticker on the airbox to pass smog check). My idea was to get just the S&B tube to the turbo and the PPE air box boot to flow better while keeping the stock air box. Things should still look stock but have better flow. I also don't know if it will pick up HP, but if i can get the slightest improvement on fuel economy, that would help (my truck is 2 years old and i have 75,000 miles on it). I know it would involve parting out a CAI set up and possible PPE set up, but it has come up before (i was just too slow to get to). Any help would be greatly appreciated on sourcing parts or even knowing if this set up would work).
  3. I just bought a used 2021 AT4 with the 3.0 with about 3,800 miles. This is my first diesel but I have read a ton of documentation, forums and Facebook groups specific to the 3.0 Duramax. When I got the truck I scrolled through all of the information in the DIC. I noticed that the DEF gauge is a about a third full. I figured the previous owner may have done a lot of towing with it because at 3,800 miles it should not be that low. Am I correct in that assumption? Should I go ahead and fill it up or wait until the truck tells me to? How much do I fill it? Until full? Thanks!
  4. I bought my 2020 GMC AT4 back in early December. I took delivery up in Montana so my first drive was a 750 mile trip home. I have driven it very little since and it currently has about 1500 miles on it. I noticed the CEL on the other day so I plugged my ODB scanner into to reveal a Code P2002 Diesel Particulate Filter Efficiency Below Threshold. It was running fine, no other apparent symptoms. Read more at: https://www.obd-codes.com/p2002 I took it into the dealer two days ago. They called me later that afternoon and said that it was a new situation and that they were working with GM Engineers to determine a proper course of action but they would like to keep it overnight. I wasn't surprised, in fact I expect that out of a new power plant and I have a daily driver. Yesterday they let me know they were Fed-Exing an "exhaust pressure differential sensor" from Lansing. They said the truck was OK to drive and that I could pick it up if I wanted. I elected to wait until the repair was completed and hope to have it back today. I didn't see this code posted on the forum so I thought I would drop this information here for others to search. I will provide another update when I get the truck back. I will also ask what this would cost if it wasn't under warranty because I think that is useful information for evaluating the total cost of owning the LM2 diesel plant. I did get an extended warranty but cost/risk and warranty coverage will be a inevitably be a huge factor in deciding how long to keep this particular rig. I really really like driving it, more than the 6.2 and ALOT more than the 5.3. I haven't towed with it yet but I hope to try that out this weekend. WALLY
  5. https://gmauthority.com/blog/2020/08/2021-chevy-silverado-gmc-sierra-tow-ratings-incoming/ Pretty interesting. I'm not sure it sways my buying decision too much as 9000 is about my limit on a 1/2 ton truck anyway, but I'm glad to see any increase even if I'll probably never use it.
  6. I just picked mine up 2 weeks ago, I did have the 2.8 duramax but wanted more.
