I used the link but no borla exhaust fits a 6.6 3500. What actual part number did u put on? I have the exact pickup u have. Just blue

[@AdventureRocks]

@@aakrefarms Yes, the site doesn't have 2024 updated yet officially, but it's same fitment as 22-23. Try changing year and seeing if that works.

Years ago I put high performance mufflers on a van I towed our travel trailer with. I had a grin like you at the beginning then the reflection of sound off the trailer constantly drove me nuts and I took them off.

[@AdventureRocks]

I hear you! Definitely a valid concern for sure. I hear it a little more while accelerating and towing or grades and towing, but not to the point of annoying. Seems they found the right balance by not over doing it. Time will tell though as you mentioned.

[@msclecarcrzy]

Cold start was my favorite! Sounds great and not annoying

[@AdventureRocks]

Thank you. I am enjoying it.

[@DavisInDuval]

I just put the crate muffler on my 5.3 and removed the resonators. Sounds awesome and didn't have to pay for full cat back.

[@maintenancethrottle]

Great review! Completely agree w/ your comments. I installed the Borla S on my 2024 6.6L gas about a month ago and just absolutely love it. Makes the daily drive so much more engaging.

[@AdventureRocks]

Thank you! I'm really enjoying it too.

[@patrickcaudill2939]

A truly wonderful video. Wife and I just purchased a Denali HD 3500 with the L8T engine (same color as yours)and I’m also thinking about the Borla system. Think I’m going to wait until next spring before changing over. Thought your sound clips were perfect, and I love how the tip exits behind the rear wheel. Many thanks

[@AdventureRocks]

Thank you for the comment! Congrats on new truck!

[@nickfountain8420]

I believe the lower trim level LT trucks don't have as much sound deadening material in them as say like a Denali Trim level would. That would be something to consider if people are concerned with the noise level inside the cab. And, that exhaust will still look almost as good as new 10 years from now being stainless.

[@AdventureRocks]

Great point!

[@MIIIB]

Just ordered one and am waiting to land. I did a few more modifications to my 2500 24' gas. Added a "catch can(J&L oil separator)" highly recommendfor prevention on valves due to DI Diamondback cover HD. I use a lot of the bed box and keep many power and manual tools. Excellent safety cover Plus resist 2000 lbs above, so any high volume items dont below can do above. Front and rear metal bumpers. I think modern vehicles made of thin metal and/or plastic body, make me think a lot if I crash at 60 or 70 mph, saw a few videos and notice the engines gone almost in front on drivers leg space. I feel a lot of peaceful driving highways knowing any crash will stop better with the metal bumpers. Waiting to buy in a few months the bedslide to increase efficiency in bedbox. 1500lbs slide it's enough. I do love my cover, no water inside the bed. Another point I change from 20" to 18" and from 275/65/20 to 295/70/18 .... I made a research, and the 295 tire gave me the same load weight (3,500lbs ) in 65 PSI as the 275 in 20. (3400lbs) 295 it's the max wide without modifying the suspension, the 70 height the max too. PLUS, since it had taller and wider walls, made the riding more comfortable, more material to cushion. I'm passing the tip since I know you tow. Not many people research about tires configurations. I do town 10K lbs t 75 psi and guess what, a LOT more control, since tires goes up to 3,900 always more lbs above than the 275 orm, and make a difference..... Thank you again for the video!

[@AdventureRocks]

Great points. Thank you for the comment.

[@mikepayne2572]

Fantastic Video. Thank you. My new truck (3500HD SRW 6.6L Gas) arrives soon. I love the sound of this exhaust. You answered so many of my questions. However, I'd like hear more video with the Borla exhaust while you are towing. Also, what does it sound like cruising (non-towing and towing) on the freeway at 65-75 while under a slight load like going up small elevation changes? If I buy an exhaust, Borla can thank you for the sale.

[@AdventureRocks]

Thank you! Great question about the towing. That was probably my #1 question as I didn't want it to be obnoxiously loud given the way towing puts a strain on engine. I'll be releasing another video in a couple weeks showing the truck going up/down a ~25% grade if that helps. Maybe I can find time to do more in future as time permits. Basically what I've found so far is that when I'm towing and doing average accelerations the exhaust will sound similar to me driving unladen but doing fast accelerations (not quite pedal to floor, but near). Then once up to cruising speeds 40-65mph the exhaust becomes almost indiscernable. Otherwise frequent grades while towing you'll hear the exhaust more than unladen naturally, but I don't find it annoying. I could see if all you did was tow with the truck everyday or if one was always towing up grades that a performance exhaust like the Borla S-Type could get a bit much in some ways...personal preference. What I've really come to like about the S-Type is that if you drive it light to average...it's pretty much indiscernable. Whereas if I push the pedal hard I hear it nice and loud. So I like that I get to choose essentially when I want to hear it for the most part. Borla did an amazing job fine-tuning it.

[@RC-iv4dx]

sounds great! i have the borla s on my f150 love it! its nice to hear it, when u get on it when u want to!

[@AdventureRocks]

Nice! Bet it sounds great on the f150 too.

[@ericlindgren9895]

Thanks for the information. Awesome video. I’m here for the 6.6 gas motor content. I have a Imagine travel trailer, still pulling it with my 2018 Toyota Tundra. I got in some bad winds last October coming from the beach & it wasn’t a good experience. I know the winds would still affect the 3/4 ton truck, but I’m sure it would’ve handled it better.

[@AdventureRocks]

Thank you. I've been continuously impressed by the modern 3/4 gasser. Coming from nearly 10 years of diesels ranging 3/4 to 1 ton, this GMC gives me so much confidence and no stress while towing. Just a really solid feel. I did a 25% grade towing test recently and will be publishing it soon. Too bad Toyota doesn't get into heavy duty trucks in USA, right? That'd be interesting.

[@slaytanic921]

For what it’s worth, I have a 2022 Silverado 2500 L8T and I tow an Artic wolf 287BH fifth wheel. I really only notice the wind when it’s head on because I feel it at the gas pump. Besides that there has only been a few times that the wind is blowing just right while I pass a semi and I’ll feel it pretty good. Towing is very relaxed for me unless there’s a lot of traffic.

[@jasonclark1153]

Just ordered the system for my 2022 Denali HD (used your link). Thanks for the great review. It touched on all the questions I had perfectly!

[@AdventureRocks]

Glad to hear, thank you!

[@rickbyfield2190]

I did the muffler delete pipe on my 18 Denali 6.2. It sounds very similar. Not too loud at cruise, but nice when you step on it. Great on a cold start up. It was only bout $75.

[@AdventureRocks]

Very nice!

[@jimellisGF_Exotics]

I've had this kit in my cart for a year now lol! The issue on Real Trucks is they don't have the option for Borla Type S, they only have the MRBP Pro

[@2WildBengals]

I had a 2014 - 1500 Silverado High Country Short box wth a 6.2L VVT Gas Engine that had a Dealer Installed MBRP Exhaust System matched with a K&N Cold Air intake and Boy-Did THAT ever sound Great!… and I traded it in and Ordered the Same Truck with a Sun Roof and a 6.6Ft. Box in a 2017 Model. II have the K&N Air Intake on the 2017 and am Planning to put the same MBRP Exhaust on it, as I know what it’s like.. very similar to this Borla, so now you have e re-thinking. I like the aggressive notes with that “Rumble” like a Harley Sound and this sounds very close to the MBRP I had. Thanks for your video- Very Well Doe Sir!

[@AdventureRocks]

Thank you!

[@borla]

Excellent video, well done!

[@AdventureRocks]

Thank you. It's a very well designed and thought out exhaust system...I can see now why it comes so highly recommended!

[@johnwinter9722]

Very helpful video! Ordered the Touring version for my '22 Silverado 5.3 with dual rear exhaust outets. Got the black chrome tips to complement the LTZ trim. Should add personality. I tow a 7,000 lb Rockwood travel trailer and want to minimize the sound intrusion when towing, at least on the flat. I had Flowmaster duals on my Suburban and the noise when towing was too much.

[@AdventureRocks]

Thank you! Bet that'll sound great on your truck and liven it up a good bit. Enjoy!

[@prettybadboylagerberg6385]

I was so hoping to hear a mileage upgrade on. My wife doesn’t understand the whole sound obsession. Definitely more of a guy thing. I’ll have to figure another angle. 😀. Thx for the good info tho bro! My 2023 Chevy HD sounds so uninteresting and it’s got that whine from the 6 speed that I assume went away with the 10 speed.

[@AdventureRocks]

Thank you. I hear you! :)

[@slaytanic921]

I have a 22, which whine? I currently have a flowmaster that went on after being straight piped so I didn’t experience the stock exhaust at all. I would have stayed straight pipe but it would have been too loud while towing.

[@roadsplorer]

Great video, well done in the sound.

[@AdventureRocks]

Thank you. I'm still enjoying it.

[@brucekelley8431]

That smile would be much wider if you add a AFE cold air intake. Great video.

[@AdventureRocks]

Thank you. Don't tempt me!

[@24snowboarder4life]

They make the cabin too loud, I ended up taking my cold air intake off and running the stock setup with a drop in K&N filter

[@patrickfearon7942]

@@24snowboarder4lifeagreed. I had a Banks Ram Air on my old F150 5.4 and it was louder than any exhaust inside the cab. I’ve done a drop on ever since.

[@MrAgray911]

Thanks. I just ordered the same.

[@AdventureRocks]

Thank you. You'll love it.

[@MartinTerry-e7p]

Have you done the 6.6 gmc gas truck with the Flowmaster American thunder system?

[@AdventureRocks]

I have not. I just listened/watched the official Flowmaster video and biggest difference I notice right off the bat is the dual exhaust sound with slight harmonic between the two outlets? Hard to tell sometimes in a video, but that'd be my initial impressions.

[@keith-s1n3k]

do you think it drones in the cab?

[@mikepayne2572]

I ordered exhaust through your affiliant link. It says no exhaust available for 2023 and 2024. Borla shows it is the same exhaust for 2020-2024. I wish Realtruck would update their website to accurately reflect what is what.

[@AdventureRocks]

I hear you. Took me a minute to figure that out as well.

[@NCSTRIPER]

Have you thought about installing the STILLEN COLD AIR INTAKE SCOOP - TP403502?

[@AdventureRocks]

Looks interesting. Have not considered it before. Is it for the Duramax or L8T?

[@NCSTRIPER]

@@AdventureRocksit is the same for both engines in the HD trucks.

[@NCSTRIPER]

[@IDWIE]

Sounds great

[@greatscott5054]

sounds great. did you level your suspension?

[@AdventureRocks]

Thank you, I'm enjoying it. Just stock suspension at far. No leveling.

[@osrr6422]

Not related, I can hear the transmission whine. Mine does the same thing (a 2024 as well). Is that an Allison thing? Seems to work fine.

[@AdventureRocks]

You know I have been listening more carefully as I drive and I think I hear what you are referring too. I believe that indeed is the tranny. Apparently normal for our trucks.

[@brianperry3215]

Did you have active exhaust on your truck before you installed the borla exhaust?

[@AdventureRocks]

Just OEM exhaust beforehand

[@mattwag11]

The HD's do not have active exhaust, in fact, only the 2024 6.2L has true "active exhaust" in a 1/2 ton Silverado/Sierra. Now, the 1/2 tons starting in 2019 have a "flapper" near the front of the muffler that makes the exhaust sound like $hit...that might be what you're talking about but neither of these were ever used on the 2500/3500 as of yet. And no cylinder deactivation (aka active fuel management) or auto stop/start either.

[@rickbyfield2190]

Does it drone inside at about 1400-1600 rpm

[@AdventureRocks]

What I like about the Borla is that once I let off the accelerator or go easy on it, I can barely hear it anymore. It's not an active system, but it's not overly obnoxious for everyday driving. You definitely hear it when accelerating though...such a pleasant, throaty exhaust.

[@211mathew]

Did borla have matching headers? I was just watching the stainless works... not sure if they have headers for 2024 or not. Waiting on email from them on reply

[@AdventureRocks]

I am not sure about that. I only did the Cat-Back portion.

[@BradKeselowski-s8n]

Does Putting this exhaust system on void your warranty?

[@AdventureRocks]

@@BradKeselowski-s8n great question. I'd imagine there is a variety of opinions on that topic. While I cannot speak for each car manufacturer such as GM, if installed properly I would say no impact to warranty, again generally speaking. I'm not associated with GM or exhaust manufacturer.

[@ByGraceThroughFaith777]

Bro made sure Google understood the product name loudly and clearly 😂

[@AdventureRocks]

Ameteur in progress here, but gotta enunciate right? :)

[@ByGraceThroughFaith777]

@@AdventureRocks oh yeah man, it's all in good fun. The video was great, awesome production value, and you explained a lot of things very well. Plus the Borla exhaust definitely woke up the truck. It sounds so much better now. That 6.6 V8 sound needed to be heard!!

[@88Petry]

Doesn't the 2024 have active exhaust from factory? So why put the Borlas on it?

[@AdventureRocks]

I don't believe so, or I should say the OEM sounded static to me on my SLE 2500 HD. It's not a bad exhaust, but more designed to be quiet.

[@mattwag11]

Only 6.2L in 1/2 tons have the active exhaust starting 2024.

[@NickRas625]

Can you add a Procharger for your next video lol

[@nickfountain8420]

I'd personally recommend a whipple. Since he's towing having the instant torque from the start would be better. Prochargers are great, but more top end power than a twin-screw style supercharger such as a whipple.

[@NickRas625]

​@@nickfountain8420 Good to know! I was honestly just implying any supercharger tho lol. Can't seem to find any vids online

[@AdventureRocks]

Don't tempt me!

[@justinturbo4323]

It's only for the 1500 6.2🥺

[@AdventureRocks]

The site doesn't have 2024 updated yet officially, but it's same fitment as 22-23. Try changing year and it should show compatibility with 2500/3500 on the L8T/6.6.
