2014 Sierra Denali 6.2 with Corsa Sport catback

Got the Corsa Sport on yesterday. The video was taken on an IPhone and didn't turn out very well but it will give you an idea of the sound. It is a lot deeper and throatier than stock and quite a bit louder when you get on it. There is zero drone but it has kind of a deep flutter sound in v4 mode. I'll be ordering an Autocal BBP tune in the near future and will disable the v4 then. Inside the cab while cruising it is quiet and has a deeper note than stock. So far I am very pleased with it.

Sounds good. I have the corsa cat back on my 5.3 and it sounds similar. Though your 6.2 might be a bit deeper. I got my V4 mode disabled with BBP as well. Good mod and worth the $$$

It's actually a little deeper in person. The IPhone didn't catch it for whatever reason.

Sounds great! I have the Corsa touring behind my 6.0 and love it.
