I have never had it with my Corsa sport when driving. Now when towing my boat there is a little drone going up hills when down shifting, but that’s acceptable to me. When cruising down interstate or highway the Corsa exhaust is whisper quiet. But slam on the peddle and it wakes up! It’s the best of both worlds in my opinion.
Others who have the GM Performance Package have stated the same with the Borla system.
I also had a Gibson dual sport Catback on my 2018 Sierra 6.2L with the older AFM and it also never droned on the highway. It’s a very nice exhaust for about half the price. But it does have it downside. If you live in wintery areas the exhaust does corrode because it’s not 304 stainless steel like the Corsa and Borla system. I think it’s 409 stainless steel.

I was looking at the Flowmaster but they are the 409. Started to look at the Borla due to it being 304 stainless. Also need to look at what I can get shipped easily to where I live. Borla easy as well as can get from GM. Thanks for all your feedback

I have been running my S&B Filter for about 14000km now on my 2019 Elevation. Very very happy with it. Have not had any engine management system errors come up. All good. They did tell me to leave the negative terminal off the battery for at least two hours so that the system automatically recalibrates when you fire it up again.

I also installed the filter back that somebody mentioned previously. I closed of the side hole. Still sounds great and very 'throaty'. Very responsive. Looking for a CAT back now if anybody has recommendations. Not too loud but want that classic V8 sound and a couple more horses as well.

I'll second @TNTSilverado as I have the same setup as him. The Corsa system is the best of both worlds for these trucks. The sound is very aggressive on startup and WOT, but shipser quiet on the highway. It's perfectly complemented with the S&B intake. The truck drives completely different than new. It really is a shame how much they restrict these things from the factory.

I installed my air intake this week and love it

Sounds amazing, I’m glad I was able to install it prior to Adding the Borla S-Type cat back. It will be interesting to hear the difference with the new exhaust compared to stock

Question about the extra cover, I didn’t install it since super warm weather and dust will not be a factor, however I’be read on this post it helps drown the sound of Cylinder deactivation sound?

These vehicles are engineered with a cold air intake right from the factory.

That intake shown, takes air from BEHIND the radiator & condenser, which is significantly hotter than the OEM location ahead of the gasketed radiator bulkhead.

Actually it gets its air from the stock OEM's 1.375"x4.25" tube opening, along with the greater opening that a person sees. Which true, is behind the radiator, but is angled to try and get the air that is coming from inside the fender well.

If the aftermarket opening is letting in most of the air, due to the factory restricted inlet, which is hotter, so be it. The temperature difference doesn't affect much after it gets compressed after the turbo and cooled back down (if you want to call it cooled down) with the intercooler. This is for the 3.0 diesel.

I agree, with a gas burner the cooler the air the better. But if the engine can't get enough air to breathe, what is better?

Anyone go from GM performance Intake to S&B?

How do we know the engine "can't get enough air" with the OEM setup?
Just like crossing a mountain pass at 6,000 feet, the turbo, by design, satisfies the engines ECM commanded boost value by adjusting it's own VNT rack. Any slight increase/decrease in plumbing restriction is easily compensated for.
