My 2019 GMC Sierra muffler baffles took a crap and are rattling. I’m out of bumper to bumper because miles and apparently my extended warranty doesn’t cover exhaust systems. Has anyone had any good outcome from putting on a muffler their self? I took my truck to the dealership and they want $1350 to do it.

You can do a bolt on cat-back from any of 25 (or more) companies.  I chose Borla.  Took a couple of hours last weekend, but I bought the dual exhaust set up so I had to cut the OE setup off right near the cats.  This type of mod is easy to do in your own driveway.

I would Google muffler shops in your area and get a few quotes. I've never paid more than $300-400 for a muffler/exhaust job (this with parts included). Simple cut and weld would probably run about $100. Get a used part off the forums or on your local Craigslist for $50 and have them weld it in. Junkyard parts are also another option for cheap if you own a reciprocating saw or pipe cutting tool.

 

Boom $150 out the door for factory parts and repair.

 

With most folks wanting more sound I always see a dumpster full of parts out in front of every shop. See if they will cut you a deal for take-offs or go with aftermarket if you want a different sound (bolt-on kit like the aforementioned Borla should run you $800-1000). There are a lot of options, just depends on what you're looking for.

What he said. A good muffler shop will weld in the muffler of your choice for a couple hundred. 
 

That keeps the factory exhaust system which is actually pretty good quality and build.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      There are knowns and unknowns.   Knowns:   - LT, RST and LTZ names/trims are gone.  The new "Silverado" trim level replaces all 3 of those.  You should be able to configure the Silverado trim to match the equipment levels of those three trims.    Unknowns:    - Custom.  No mention of what engines it will have access to.  Dual exhaust being standard does seem to confirm a V8 option for the Custom trim though.  My "guess" is that Custom will have access to the Turbomax and the 5.7.  I could be wrong though.  The current Custom trim went 2.7 Turbomax only the last 4-5 years, and only had a single side exit exhaust.     - 40-20-40.  I would imagine that is NOT going away.  They only focused on showing the new interior on the top trims, Trail Boss, ZR2 and High Country, hence the images shown are just bucket trucks up front.         The info should start coming fairly quickly over the next weeks and months.  Production is supposed to start up later this year, so when the order guide launches, you'll be able to see the configurations of engines, cabs, seating, etc.

      I don’t do offloading other than a dirt road literally for me it’s more about the look which I really appreciate a nice looking truck and I like sitting a higher and not just because I’m 5 foot seven lol..  I’m also not compensating for anything lol..  but I truly think it’s safer on the road the higher you sit you have better visibility generally speaking especially a few of your Sideview mirrors adjusted correctly. They do make a programmer rough country does they’re $1000 for these new 2500s but when I do a gear swap that would be a moot point. A lot of the shops that I go to in my area they’re all saying the same thing that Yukon Detroit axle Eaton Spicer Richmond they don’t have gear shot for these trucks which surprises me because hasn’t this body style been out since 2020? I’m hoping soon they have something because yeah I’ll have to spend the 3K to get both axles done. Thank you for all of your response responses. I apologize if there’s any grammatical error errors as I’m doing speech to text on my iPhone without proofreading

      I guess I don’t look at it as extreme I had 11 inches on a 1500 ram with 38 I had a 4 inch on a OBSF350 with 37 I had a 4 inch on an OBSF 250 with 35 and I’m not really into off-road I just appreciate good-looking vehicles this truck will never be offloaded other than maybe a dirt road    I mean the factory is even putting 37 on Broncos etc. Raptors they know what people want

      OCI, not when but why?

      By asilverblazer · Posted

      Topic: OCI, not when but why? Have you considered that just because there is limited documentation on GM's programming of the OLM system that it is not a sign of it's simplicity but a protection of intellectual property? We both agree the system's published parameters are too limited to present an accurate picture of oil quality.   I am not discussing my oil change routines in this comment, I am discussing the parameters of the GM OLM; a key component of "OCI" when and why.   You know what I find interesting? GM trucks, discussing things relevant to those trucks.   If free conversations are not allowed in threads you start I suggest having a discussion with a moderator to have them grant you authority to police and suppress the free exchange of thoughts on your topics accordingly.   Alternatively, if you only want to talk about oil without distractions I suggest bobistheoilguy.com or starting your own blog.   Carry on your discussion of "Engine Wear and ISO 4406"

      And I was thinking of this factor as well in that if a customer does not well maintain their vehicle ( which means going by the manufactures schedule in most cases ), that vehicle in theory by the time they trade it in or sell it privately will have potentially a shorter life span on some major components as a result and so that vehicles life either cut short or a lot of parts thrown at it to keep it on the road. In either case the manufacturer wins because its either selling more parts or that vehicle has hit the grave yard and becomes a win win for the manufacturers. So indeed the salesmen love a scenario like this .. yes yes, treat that vehicle I sold you like garbage so I will be seeing you sooner then you think for your next new vehicle purchase  ! 😆   OnTheReel, I looked up my OLM percentage for the last oil change that was done with 2500 miles on it and it read 48% and that was an interval through the winter so more idle time and so on and while not scientific, when I changed the oil it had this weird color to it that I can't say I have seen before and to keep in mind that I burn dyed fuel but so does all other gas vehicles I use and I have to wonder if fuel dilution and allowing more of that dye into the oil was showing up or what but it sure didn't jump out at me as saying I was dropping the oil way too soon. Instead it made me think of what a local long time mechanic had commented on with my truck that he recommended I change the oil every 2500 miles as the number one thing to keep this engine type in good mechanical service. But again its not like that oil was sent to a lab to see where its life was at so this is only anecdotal.
