So is it counter clockwise or clockwise??

Mine was clockwise, which was rotating it towards the front of the truck.

Exhaust Mod:Frio Edition.  dB levels were captured before and after mod in same place. Flapper open.

So then don’t do it and be on your merry way. Some people like it some don’t. It does change the tone for the better IMO. Carry on Sent from my iPhone using Tapatalk

Frio Light, LOL! Nicely done! 

 

Thanks for measuring the dB on this. I was curious about that myself. 4 dB improvement while idling is pretty good. 

 

Was that on the cold start? I really notice that it's louder on the cold starts. Sounds really good.

No cold start was definitely louder. I waited till it was a true idle before measuring

Just look to see which direction you turn it makes the spring load up more tightly. That's the way you want to turn it. Mine was clockwise to do that.

Add me to the list. Just finished doing this cheap mod. Had everything except a few clamps so it cost me under 10 bucks. Haven’t tried it out yet. I met resistance turning clockwise. Will report back

I'm wondering if there's a way we could buzz that little notch off on the flapper valve? The part that sticks out by the welded end, which gives compression to the spring? You cut that off and the spring will loose it's pressure, meaning you won't have to worry about those clamps loosening over time and the valve slowly shutting. 

 

It's probably unlikely that the clamps would lose bite and allow that, but it was something I thought to check after a few days of running mine wide open. 

 

Then again, I did tighten my clamps down with my cordless impact, ha.

Of note, I have noticed that my exhaust has been crackling and popping a bit when coasting into a traffic light to make a turn. Didn't do that with the flapper in it's regular position.

 

I tried removing the last mesh screen cover to see if that might make it stop.

Never knew about the res screens... I have a flowmaster 40 series muffler I installed a while back, but just covered the screens w AC tape...  much deeper tone...   

 

Thanks for the idea...

 

For you beer can users... Ghetto fab... Strong work.

Thanks for the feedback. I haven't noticed that yet. I'll report back if I do.

I thought about it but then the Texas in me wanted everyone to see the Frio label. Maybe Frio will sponsor me.

Redid the flapper this time clockwise, dB shot up to 66-67.

That makes a lot of sense. Opening that thing up really makes the biggest difference. ??

      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.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
