Once you hit 3000 status you can't make a change. But I wouldn't sweat it. Corsa is already on it and will have an aftermarket exhaust that will be much better. I might jump on a Corsa exhaust and I'll sell you my NPP if you want.is there any dealers on here that can help me out ? I forgot to order the performance exhaust option and I called today to see if it can be added on. my dealers said the status has moved to 3000 and he was unable to make changes, does anyone know if the changes can still be made?
