Were there any issues installing the exhaust hanger on the drivers side with the ATAK system?  Seems like the class III hitch might interfere.  This pic is from my 2018 Sierra.

Not at all, they have a hanger that is provided in the kit that bolts up using the hitch receiver hardware. Just make sure you torque it back down to the hitch receiver specs. I would post a picture but unfortunately my truck is in the body shop. During the most recent snow storm a plow took out the passenger side bed side and rear bumper.

So the hanger will fit in between those two metal parts of the hitch?  Every time I see an install on you tube, it’s for a truck without an OEM hitch from the factory.

Yes, I took the nut and washer off the bolt that is closer to the wheel well and slid the bracket on. I did not have to remove the hitch receiver, it slid right on then torqued it back down.

Quoting myself but...

 

I love the sound of this exhaust except at 1800-2000 RPMs, for some reason in that spot I get a drone, not horrible but certainly noticeable ?

that means that if I am getting up to speed at a slower pace to conserve fuel it hits that RPM range in a couple different gears.

 

Stock exhaust has resonator after muffler, would installing one after the muffler tone down the drone at all?

If so, any recommendations?

Following up, 

 

I added a Vibrant 1794 in the stock resonator location and it made a huge difference in the drone at 2k while smoothing out the entire range of sound.

For me it seems about perfect, I have a highway trip this weekend so we will see how it sounds @ 75mph for and extended period.

 

Now, if I could just keep my foot out of it so get my mpg's up ?

Good evening. Looking for some

help as I thought I ordered the correct sizing but reading more looks like I ordered too small. I bought a 2.5” I/O Flowmaster FlowFx to do a muffler only replacement. It looks like many people are doing 3” but I see also a lot are doing 2.5” out for duals. My question is if my 2.5” I/O will work or not?

Stock 5.3 = 3” and stock 6.2 = 3.5” so nope, 2.5” is no good. You have to change exhaust from manifold back or y-pipe back for it to work.

 5.3 is actually 2.75” from Y-pipe connection to tail pipe. You’ll need 3”-2.75” reducers, have the factory pipe expanded, or have the muffler welded on if your just doing a 3” muffler swap. Walker also makes a 3” stainless intermediate pipe (pn 55608) that will work on these trucks.

recently purchased a 2016 5.3 with a 12" glass pack and turn down. NOT keeping that setup!

 

from looking under the truck, it appears they welded the glass pack on where the stock muffler was removed.

 

looking for suggestions on which exhaust system, cat back i'm thinking, would be nice and quiet in the cab.

TSP headers and y pipe with stock resonator (as a muffler) and the boom tube tip. Absolutely love this setup and hopefully soon can learn to weld a stainless 3.5" or 4" setup.

Just bought some TSP long tube headers with catless ypipe (so they said but look more like speed engineering) to go with my Corsa Performance Exhaust hope it sounds good, exhaust is for a 6.2 kinda like this setup because the ypipe has a swapable end for 5.3 or 6.2 bought this used so let’s hope this was worth it!!!

Are you sure those are TSPs? Mine have ball flanges and didn’t turn that color. May just be an earlier version. Corsa will sound badass but it’s going to be loud AF.

They look more like Speed Engineering to me. I’ve heard good things about them but hopefully he didn’t try to sell you something for more then he paid new.

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.
