Have they fixed that issue for you? , it sounds really good but I don’t think I could put up with it not working properly for that much money.

basically no... the issues kinda fixed itself now.

however I had Corsa systems on my 2011 and 2017 Silverado before this and I know Corsa got my back if anything goes wrong. they'll send you a new muffler. register your products.

mine also could have been an installation issue with the alignment of the valves, I wouldn't worry about it id trust them to make it right if there is an issue, but most likely there wont be

Yea surprised to hear about the issues but Corsa is a company that I would think will stand behind their product. I like the distinct difference between the modes, torn between it and borla s type.

I have the corsa NPP. In stealth mode it’s super quiet even with long tubes and Catless mid pipes. Open it’s louder than stock but it’s not as loud as the extremes. Even with long tubes it’s pretty tame and sounds good. High rpms it’s loud but under normal driving it’s perfect.
