Did you just replace the muffler, or did you do the cat back/

So I had an rst with a 5.3 and I did a full s type cat back

 

i now have an ltz 6.2 and I did the s type catback on this truck as well. 
 

They both sound great. The 5.3 has less drone and sounds a little quieter

Don't discount the Gibson. Just put on my 2020 6.2L. Not too loud, but lower growl and to me sounds great. A little of the "helicopter" sound people talk about going 40-45 MPH other then that no complaints. Just saying and for the $478 I paid with shipping cant beat it..

Any particular name, model or part number for the Gibson system you used?

I can tell you, for the money I spent, the sound in the cabin is not too overwhelming, it does take a little getting used to the DFM switching back and fourth, but you will have that with any system. There is a "beefiness" to the exhaust tone now but not so loud you cant think. Its got a loud cold start up, but that almost completely goes away by the time I pull out of the garage. So again don't discount it, it was super easy to install on my own and great quality for $478..

I had the Gibson dual sport Catback on my 2018 Sierra 6.2L and I enjoyed every minute of it. I paid $480ish for it and the startup and deep snarky growl when getting on it was nice!  Yet it was very quiet on the highway driving. I had the older AFM system and didn’t notice it on that system.  
Glad you like your Catback.    If they would have made the system for my High Country’s standard bed I might have gotten it again.

Does anyone have experience with the Flow Master FlowFX ? Just wondering how it stacks up against the Borla Touring. I loved the Touring on my old truck. It had the right low growl and volume for my taste. The FlowFx sounds good on their youtube channel but can't really tell what the volume is like. Also at half the price of the Borla is the quality still there?

I put a Flowmaster Flow FX muffler on last week. It sounds really good. The tone is deep and there isn't any drone. I paid $100 for everything.

I do not really remember and I have since upgraded to a 2500 Duramax so I can’t look either, sorry.

I installed the Flowmaster FlowFX Cat Back on my 2021 5.3 Silverado. I can tell you without a doubt it is a terrible choice of muffler. It is loud. Straight pipe loud. The interior sound level around town and on highway is unbearable. And the noises caused by the DFM are just irritating. Unless, of course, you want your truck to sound like a performance boat, than the FlowFx is for you.

 

If you want real Flowmaster sound, go with their Series 70 muffler.  That's what I did. I will be starting a thread over the weekend detailing my experience with the Flowmaster FlowFX Cat Back system.

What is this helicopter noise you are talking about, even with a full cat back system?

      PF63 Oil Filters Going Away?

      By Atlas · Posted

      I only have a few of the ACDelco blue remaining. One or two of the (old, old) ACDelco Professional boxes, and a couple of the newer style GM boxes with the simulcast in Chinese along with English. FWIW they've all been pretty good, regardless of where they are made, and in 20 years I've never had a problem with an e-core filter.   Now I have a couple of the "A" series in my home inventory. They come in a plain white box with the GM hologram sticker and model information. Have not installed one yet, want to use up my oldest inventory first.

      I suspect at some point in the near future, the hardware will be free and you pay a subscription to access the vehicle - alldata style.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
