    Great Sound

    Best sounding exhaust I've heard in a very long time. Installed the high flow corsa cats at the same time. This installation did cause a CEL to pop up so hopefully there is an easy way to resolve this issue but otherwise, very happy with this product!

    Sounds amazing

    I’m in love with the sound this exhaust produces, it makes a huge difference. The exhaust makes it sound a lot deeper and definitely a big upgrade to the overall sound to the C8.

    #21102 Corsa Xtreme Cat Back 2020 C8 Corvette System

    I had my Corsa Xtreme exhaust #21102 installed today. My first impression is WOW! My C8 Corvette is a HTC ordered with a non NPP factory exhaust system (non performance factory exhaust). I knew if I was going to remove my factory exhaust for a Corsa exhaust system as I have had Corsa products in the past on a C5, C7, Silverado 6.2 and now my 2020 C8 Corvette. There were 2 options with Corsa for my C8. One system deletes the AFM totally and one option uses the AFM function. My factory exhaust had a nice rumble on cold start up and nice when opening it up, but really quiet for most driving. I choose the #21102 for the AFM valve option. My first impression was a great sound at idle, nice sound when normal city driving and not nasty when just tooling around. When I opened up now, it roars! I took it on the highway and it is not terrible, has nice rumble when just cruising in traffic and normal travel. It really wakes up in sound once I step on it, not the weak and quiet factory sound. I personally don't think it is to much for most driving, but in the city during stop and go, having fun with a more spirited driving it sounds great! Even has a nice rumble at idle and at stops in traffic. My first impression is a awesome one and is what I am looking for. I will follow up later with a further overall experience to share.
