Aftermarket Exhaust - Arizona - AWE/Borla/Flowmaster/Rough Country

Hey everyone,

 

I've got a 2025 Silverado 1500 5.3L and I'm looking to upgrade the stock exhaust. I've gone down the YouTube rabbit hole listening to a bunch of different setups, but it's just hard to judge how loud they really are without hearing them in person.

 

Right now, I'm considering:

  • AWE 0FG** (this one is my top pick so far—love the tone, just worried it might be a bit too loud)

  • Borla S-Type

  • Flowmaster American Thunder (not sure if it's actually much louder than stock—also worried about drone)

  • Rough Country (seems like a budget copy of the Flowmaster?)

 

If anyone in Arizona (I'm in Surprise, but willing to drive a bit) has one of these setups, would you be cool with me meeting up real quick just to hear it in person? Would really help me make the right choice before dropping the cash.

 

Appreciate any help!

I had a 2023 Silverado HD with a 6.6 gasser and I did a ton of research - ended up putting the Borla S-type. 

The Borla sounded AWESOME and it had zero drone !!!

If you go on their site or just search for Borla on 5.3L, you should find a video that will give you a real good idea of how it will sound.

The Borla was also super easy on the install.

I'm in Phoenix thinking about exhaust and would be interested in joining the fun, haha! I've been leaning towards Corsa.

My neighbor's son has a new 5.3 and put Flowmaster on it. I could try to catch him this weekend to see if he'd be willing to show it off for you. I don't know about drone, but it's none too loud, in my opinion. I was actually shocked how quiet it was with no muffler at all. (The piping in the kit didn't fit so he drove it over to a shop to get welded on.)

That would be awesome, thanks!

Where in Phoenix are you located? Feel free to PM me.

Do you know what his whole setup is? (Cat-back system, which muffler, resonators, tips)

Yeah I like the sound of the Borla too. I'm still not sure how loud it is exactly. I also wish the Borla had 4" tips instead of 3.5"

I'm off of the 101 around 7th st.  It's cat-back and he just did a turn down, iirc. I'll have to ask which muffler.

Cool, thanks! I'll let you know if I can make it out that way.

Really appreciate the offer, but Casa Grande is a little far for me. I'm out in Surprise.

I live in Michigan and we don't believe in emissions. So I went with the cheapest option, muffler delete, and it's never led me wrong. I did this for my old 2017 Silverado 1500 LT 5.3L (single exit) and on my current 2023 Silverado 1500 RST 5.3L (dual exit).

 

The 2017 cost me $80 and the 2023 cost me $100. Definitely has some rumble from cold start or if its back up to a wall/garage, but there's hardly any drone and is pretty quiet when you're just cruising. 

 

I will recommend the same thing I told my friend, I would try this first before spending a lot of money on a nice exhaust (he couldn't decide what brand either), because worst case scenario is you burned $100 and you end up putting an exhaust kit on anyways, but best case scenario is you get the exhaust sound you were hoping for while saving thousands. 

 

End of the day its your truck and your call just my 2 cents

I just put a new dual exhaust on my Sierra 5.3 in March. I got the Flomaster muffler and the shop did the custom pipe work. I converted from single exhaust to dual and cost out the door was $700.  I don't know how loud you wanna go? ......but this setup is not extremely loud. I told the guy at the shop I did not want something annoyingly noisy and loud, just give me a good V-8 engine sound.....and that's what it is. I do not notice any drone. On the highway it's not much louder than stock. It has that deep throaty rumble on startup and driving at low speed. My neighbor has a Ram with a Borla and that thing sounds like a dump truck roaring......perfect example of what I did not want.

AWE is louder than F*CK but sounds great, ZERO drone.

Corsa Sport sounds GREAT and is only loud on a cold start for a few moments.

Borla S type and corsa sound close to one another both  excellent quality with no drone.

Cheapy systems will add drone and not last as long.

I learned a long time ago, buy once cry once ...lol

the muffer delete gives too much drone if you do much freeway or distance driving.

I've heard the same about the muffler delete giving lots of drone, especially if I delete the resonators. I'm seeing mixed opinions on the AWE though, some say it's really only rowdy on cold starts or hard acceleration, but regular city driving and cruising are more tame with a nice rumble. What's your opinion?

Which Flowmaster? Do you have a video?

The AWE is as you stated startup, cold idle and when driving aggressively.

I went through.... delete, corsa sport and borla touring (way too quiet for me)before ending up with AWE.

Next will be headers and a true dual with AFM delete kit from Texas Speed along with camshaft and tuned by wifi, then adding the whipple and heavy duty drive shaft and dyno tuned by LMR.

Then I will call it DONE with this truck and onto Wifeys Escalade V which is LOUDER stock than the Silverado when the valves are open AND has more HP....

I think he said it's a 50? if that makes sense. I would have to go check the shop invoice for more info on it. I don't have a video at this time.

If you are still looking for, I have a 22 Silverado 1500 5.3 with Borla S-Type and K&N CAI.

 

No drone unless you get on it.

 

I am in Mesa, but willing to meet somewhere between.

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
