After trying 2 exhaust systems and not liking them, I am glad I didn't cut my stock exhaust. Find a stock exhaust Craigslist first, then start trying different combos of mufflers

 

I've had 5 different mufflers on my truck.

 

Stock OEM muffler

Magnaflow 18"

Magnaflow 14"

Flowmaster 40

Flowmaster 10

 

With all the $$$ spent on those mufflers I could have had a high dollar cat-back!!! :nonod:

Luster isn't it 6? IIRC you also had a 22" Magnaflow for a bit.

Haha... yeah I think the 18 was a 22, then went with the 14. ;-)

Get a xr1 multicore the round one.. Clamp open the valve and remove the resonator. And then your choice of single or dual tips...

You will get a lot of different opinions on this subject. YouTube has a lot of different videos with different mufflers. I just put a Carven tr on my 14 silverado and removed the flapper and resonator and love the sound and almost zero drone. I have a video on YouTube listed under Carven TR muffler.

I just put the carven tr muffler on my 16. I left the rear resonator because I didn't want drone. But if I can take it off I will. And how loud is it because I don't want loud

 

I do have a dynomax mini muffler I bought I could out in place of the resonator to quiet it down a little

Why clamp open the flapper instead of just removing it?

Because it will give you a good idea with it off.. if you can handle it then remove it... but if it's too much then you have it already on..

Mine is still on.. but mine has been clamped open for a long time now.. finishing my exhaust soon and then I will remove my flapper cause I can handle the small drone I have...

Makes sense. Did not think of it that way. What makes the xr1 round better than the oval? I have been curious of this for a while now and have not had any luck finding an answer.

Don't know I've never tried the oval... I wanted a 3.5 inlet from borla and I wanted about the same length of a muffler and I picked the xr1 multicore part# 40722.. pricey but we'll Werth it

And im not 100% sure but I think 40722 muffler is the attack cat back muffler muffler.. but for a 6.2 cause it's 3.5 inlet

Yeah I have looked into it and it is like $140-150. Not a bunch more than magnaflow or flowmaster, but I feel borla will be a better product.

I spend days upon days reading up on the different exhaust systems for my truck (before I even had it). Listened to about 300 different exhaust clips (fabricated number but every one I could find)

 

I picked up my 2017 Sierra Denali 6.2L Tuesday evening & had it at my buddy's shop wed morning at 9am.

 

I deleted the muffler & flapper valve, replaced with a straight pipe but retained the 3 cats & resonator. When it starts up it's got a mean little grown but then relaxes into a nice idle.

 

Daily driving it's subtle and easy to drive with highway or city. And when you want to be noticed you step into the accelerator and people notice it! For even more fun drop a gear or two as you are coming to a stop, sounds amazing!

 

I was doing some "spirited driving" today and had an older gentleman (65 to 70 approx) roll his window down at the lights and tell me "real nice truck, sounds like a corvette!!" I told him that the 6.2L is based off a corvette motor and he smiled, told me he was a little jealous, and asked me to floor it when the light went green. I obliged ! Ha ha

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      Thanks for that, yes just because I could I measured what came out just to give me some guidance although I already knew to expect it to take at least 9.5 to just throwing in the whole 10 quarts off the shot and doing a one and done heat cycle to drop out the excess to get to the proper level. I don't recall exactly now what I measured that came out but was less than I put back in, I knew I spilled some on the garage floor but the main part was that I was thrilled in the discovery I did not have to touch my exhaust to flex it down. The gasket manipulating is a pain of course to create that clearance to take the pan out and put back in but its all very doable if one is careful and not forcing the gasket to flex too much. From the quote I got at a transmission shop of 900.00 here in Canada ( never asked at the dealer what they charge ) I saved 700.00 doing it myself after paying for the supplies so that to me paid very good wages !, and I knew what fluid was put in and that I had changed the filter and that the level is correct without any doubts.

      Tonneau cover and rack combo

      I found a setup that lets me open the cover partway with racks installed, using side-rail-mounted systems for easy access.

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Typically its said and I agree so far that the engine oil drain plug oring is not required to be changed out unless you see some damage happening to the oring as apparently the oring lasts well. The dealer I have been getting a few parts from never even stocked the oring but instead stocked the whole drain plug that comes with a new oring which for the dealer is easier because they just throw in a new drain plug if there was any question about damage on it as well and charge the customer accordingly but again only if it is needed.    Also a hint about the drain plug oring to help it last vs a risk of causing damage to it, after its been removed and wiped off or washed off ( that is a whole other topic about some solvents damaging orings because some solvent types do ) to make sure to relube the oring with a bit of new oil so that it won't "grip" on the sealing surface of the pan and needlessly stress out the oring. Its no different than putting some oil on the sealing ring of the engine oil filter. So I just grabbed a new drain plug to have on hand although more recently bought just the oring as well but as its special it costs half the price of the drain plug ... !   Since you mentioned the hate to be empty handed theme, I am not sure what you have in the way of filter removal tools as I like using the exact sized for the filter steel 1" wide band with side to side swivel handle filter removal tool, and it can be used to snug up the filter without risk of damaging a filter as well ( its probably a lisle brand I have ). The drain plug hex size is 15mm and I always like using a 6 point socket if I have a choice and with this truck I've been using just a 3/8 ratchet that has a fairly long handle. Do you have a funnel that will work to pour oil in as that is definitely the short coming bastard part about the design with that fill port on the valve cover on such an angle that no normal funnel will even work. There are adapters and things on the market that will set into or screw into that fill port, I didn't want to deal with US shipping as that is all I was seeing at the time so caved and bought a Lisle brand multi vehicle fit adapter funnel kit and it really works well but there are much less expensive adapters out there that work in conjunction with an off the shelf funnel that would do the job also. Now that I have it, I like how it works and works so slick with the shape of the Amsoil 1 quart containers I have now switched over to. Whatever you do, have a funnel system of some sort as you will be swearing if you dropped the oil and then realize you have nothing to properly pour new oil in without spilling it all over the engine !.     Other comments, quite a bit of oil flows out down the filter when its cracked loose due to the housing above the filter so let it dribble down the filter until it slacks off flow and then remove the filter to create less possible mess. It seems these engines can sit for quite a while and drip and if you have time let it sit there and drip out of the engine as much as it wants. Also a good time to grease the 9 zerks on the front end, that's my typical practice anyway to grease the suspension and steering each time I change the oil. And remember to reset the oil change minder ( not something I am used to doing with older vehicles and equipment ).
