I have a non-turbo PT Cruiser. Pay no attention to taping anything. That tube you see going towards the fender is what you need to take out. It will be a pain to get out, you need to do some prying, but it'll come loose. Once you've taken that one out, you'll really hear a difference. I think the white silencer brings more power, and the black one brings more sound. Get a K&N filter and you'll be set.
