I got them installed a few weeks ago and finally the remote shipped the other day so its all set up now. Its super loud with it wide open. Im glad I can close it for cruising around. As long as it lasts Im happy with it. I put it as far back as possible so I dont notice any fumes.

Yes I added a punisher skull while I was down there working on it.
