I want my car to be a lil louder, because before we got the cats put back on it sounded GREAT, ever since then its been a lot quieter. I have shorties, a catted x, and a catback. My dad wants me to keep the cats on because he said he paid too much money to have them put on, and then took back off. So i'm probably going to take the mufflers off, since that will make it louder, and I'll still have some backpressure from the cats. think thats a good idea???
