    CORSA PERFORMANCE 2020 Corvette C8 3.0 IN Cat-Back Twin 4.5 IN Tips (Without Factory NPP) Review

    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!

    Not a bad install at all, 2021 C8s will throw a CEL, luckily quick call to Cicio Performance and their plug and play modules fixed the issue. Car sounds amazing like it should!

    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.

    Great exhaust - no codes or errors

    Great exhaust. Went with no valves or mufflers. Definitely double if not three times louder. Especially in 2-4 gears above 2500 rpms. But on the highway in 7-8 gears it quiets down to an enjoyable low highway sound. Exactly what I was looking for. You will not regret this if you are really wanting to wake this thing up and have enjoyable highway cruising. Very rarely goes into v4 but when it does it is not that bad. With a mode and different settings this exhaust is still manageable. Did not throw any codes at all. 2020 shadow grey coupe

    The instructions say you can delete the NPP valves without throwing a check engine light.....That might work for the 2020's but not true for the 2021 C8. It will throw a CEL every time it does not see the NPP valves.  I have a dear friend that works for a Chevy dealer and that has the scanner/software to get into the C8. He did a relearn on the AFM valves and it still threw a CEL after we unplugged the NPP valves. I fabricated some brackets for the NPP's that had stops to simulate the valves being installed on the car. They are similar to ones Corsa provided for the AFM valves except they have adjustable pins instead of slots cut out. They worked and we were able to get rid of the CEL. The Exhaust sounds fantastic! It IS pretty loud but this is the straight pipe option so that's to be expected. I would buy them again.
