Placing my order next week for 2020 Sierra 1500 SLT with 5.3L.  After reading your comments, My take on the Performance Exhaust is that it's a worthy upgrade, not obnoxiously loud but a noticeable change from stock with a slight performance improvement.   I've added it to my build.  Anybody want to talk me off the ledge before Monday?

The exhaust isn’t obnoxious at all but certainly a noticeable difference over the stock exhaust which is basically silent at all engine speeds.   If I’m honest, it was a little louder than I

Curious On this . These “Catback” exhaust systems are just that, from the cat back replaced. why pay all that money to replace GMs OEM piping which is already stainless!   The only

I am stuck between this and the Corsa sport exhaust and GM's Exhaust. I keep kicking around whether I want to spend $1300+ on an exhaust. (Or should I say my wife is the one who is saying it's not worth it!! LOL) The Corsa Sport is a bit louder when accelerating, and only one that is available on standard bed. The Gm Exhaust is essentially the Borla Touring. Borla's S-type is the one I would go with, but they do not have it available with the standard bed yet. Should be ready by end of month is what they told me??

 

You can't go wrong with the GM Exhaust though, if you're looking for added performance, not obnoxiously loud, and no drone, then go with it! Good luck and post a few sound clips.

And I’m actually stuck between 3.0 diesel (in which case the exhaust upgrade isn’t available) and the 5.3 with performance exhaust. Ordering a short bed SLT loaded so the 5.3 with PExhaust is actually a few dollars less if you compare the $2495 diesel up charge. Have driven German diesels since 2014 and the in-line 3.0 GM diesel is sweet and comparatively refined. Now that it’s been on the road for 1+ years I’m guessing the kinks are worked out?  My experience is that diesels like highway miles.

Totally agree. I have heard nothing but good things about this new diesel. It is quite, very quick for a diesel, gets excellent gas mileage, pulls very well. You can't go wrong with it if you like diesels.  I have never been a diesel guy, so that's why I went with the 6.2L.  The neighbor guy next door who owns a boat dealership, bought a new 19 5.3L last year and now is thinking about getting a 3.0L for his company truck, he, like you has said, let GM get the kinks out of new diesel, then going to buy one.

I've got it on the 6.2 so maybe a bit different, but I love it. It's right on that fine line of a nice noticeable exhaust note and obnoxious.  It sounds great in sport mode, but is more low key in regular mode.

The cold start is loud, not gonna lie. I feel a bit bad for my wife starting it up at 4:30 AM for work.

I just ordered the Performance exhaust and CAI through GMC accessories for my 2020 6.2 -though it did say that there is a 7-10 day back order. I was looking at GM sellers that gave discounts and what the shipping would be. Also knowing that putting the CAI on myself would mean taking it to the dealer for the computer update.

When I was on the GMC accessories site, it showed a discount based on how much you spend -which ends June 30th.  

Long story short, I bought them both with a 20% discount and no shipping cost, plus I'm having them shipped to the dealer to install -TOTAL INSTALLED cost for everything is $2,200.00, which IMO is pretty good. 

Got the truck back and I'm very happy with it!

The CAI cleans things up under the hood and looks like OEM -included the re-flash.

Really like the exhaust. Great sound when starting or accelerating, but nothing really different at 65-70mph.

The fit and finish is great, with both tips lining up just like they should.

I didn't do before and after recordings, since Zane Merva has the complete set available on his Truck and Product review of the one that they put on the Silverado. They are exactly what you get!

I love that they are now factory warranted and the paper work indicates to add both the the vehicle build for my VIN.

I'm partial, but I would go with the Borla S-Type over Corsa and Borla actually builds the GM exhaust. Its pretty much Borlas touring exhaust. My Borla and CAI installed was $1500. Expect to pay over $2000 for the others.

bigdog2005, 

Did you have to have the computer flashed after the install? How do you like it? Thanks I am leaning your way.

Got the 2020 Sierra Denali 6.2 with the CAI and  CAT Back exhaust.  EVERYONE asking...IT’S WORTH IT!  If you’re thinking about it,  get it!  It sounds AWESOME!  It’s not obnoxious.  It’s not noticeable at cruising speed but off the line and under hard acceleration it sounds powerful and bad ass!  I highly recommend it!

I did not have to have it flashed and seemed to wake it up. The GM package is overrated, overpriced and the so called flash makes no noticeable difference. When I inquired about it at the dealerships performance shop, they are the ones who told me to go aftermarket that the GM CAI and exhaust (made by Borla) was okay but better options.

The Borla is less expensive than the GMPP exhaust, but unless they have added it recently they don't have one for a crew cab with the 6.5' bed.  It is easy to install the Borla yourself and it doesn't affect warranty or emissions.  The CAI does need to be emissions legal.  

 

So for many, the GMPP is the only option and if you buy and install yourself it's price isn't terrible.  The dealer told me the only thing the flash did was delete the air filter minder alert.

Thanks guys. As soon as I can afford it I'm going to do it. Need to make this thing growl a little bit.

On the Chevy Accessories site, there are three different performance exhaust upgrade systems.  There is the one that is the GM Performance exhaust, pn-84527234.  The other two are identical to each other except they come with Borla tips pn-19419433 and 19419437.  I noticed that the GM Performance one is a single in/single out muffler, and the other two are single in/dual out mufflers.  Is one system better than the other?

Is anyone familiar with this Borla system from GM?

I am no expert but I think the one on the left is an upgrade for factory true dual exhaust systems

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou
