I have a 2016, but they're all the same 2015-2020. The 2021+ trucks use a dual exhaust factory, so I assume that's why the Corsa exhaust is dual. Unfortunately Corsa doesn't make a dual version for 2015-2020 trucks and I'm sure the 2021+ system won't fit the older trucks. Gibson makes a dual system for our trucks but Gibson is trash compared to Corsa. You get what you pay for.
Your 2020 Tahoe calls for the Corsa 14859 (which is a single exhaust).

I went directly through Corsa on their website (linked above). Once you start the checkout process there's a place to enter your GOV-X credentials for the discount.
FWIW, I am absolutely thrilled with the Corsa exhaust. Coming up on six months of ownership and probably 6000 miles and it still sounds like it did the day I installed it and it looks great, too. All of the connectors and clamps are in pristine shape. The Norma joint at the cat is leak free and secure. The tips have become a little discolored from constant black soot buildup (my truck must be running a little rich), plus I don't sit and clean and polish them up. Otherwise I love it and it was worth every penny.
I don't have any video, I suppose I can take some but I find that videos don't really do the Corsa justice. It is LOUD at cold start. Like, my neighbors probably hate me - that loud. After about one minute, it settles down into a low deep burble with that classic Corsa tone, but man...cold starts can be fun or annoying depending on the circumstance. I've gotten used to it.
Around town driving the Corsa has this beautiful Corvette-style rasp/gurgle outside the vehicle that makes people do double takes. It sounds incredible and gives the truck a whole different feel. Hard acceleration is downright raucous and makes my Suburban feel like a sports car. You won't be able to keep your foot out of it.
On the flip side, cruising on the highway and around town with light throttle it's VERY tame, no drone or resonance whatsoever. Quiet as OEM inside. That's one of the things I love best about this exhaust, it's whisper quiet when you need it to be and it's a very refined kind of "loud". I've heard nothing else like it around where I live.
Not really. I wanna say my MPG maybe went up a tick from 13 to 14 but I can't say the exhaust was responsible for that, it could just be the warm weather. Any power increases I might perceive are most assuredly in my head. It's still a 6000 pound vehicle. An exhaust isn't gonna make a dent and that's fine because I didn't buy it for that. I bought it because I wanted the best quality replacement exhaust out there comparable or better than OEM with a unique and classy increase in sound and I got both of those things.
One thing to keep in mind is the flapper. Corsa doesn't use a flapper valve (most all performance exhausts delete this also). The exhaust flapper valve makes the exhaust sound less weird when "V4" mode kicks in on the AFM system. I have my AFM disabled via tune, so I have no need for a flapper valve. I assume if you have AFM enabled and you don't have a flapper valve, the exhaust might sound "choppy" or weird when the truck switches from V8 to V4. Maybe someone can chime in here with more info on that. Realistically though anyone with one of these trucks should have AFM disabled by now, anyway.
