Ok as some of you know (or not) i got myself a 94 gt and recently (about a month ago) got the magnapack catback installed. I have noticed that during start up (and after a while) from a cold start the exhaust isnt loud. But once i drive it around for quite some time and get it all warmed up, its super loud. not sure if that makes sense. But anyways, is this a cause for concern? is all the magnapack systems like that? Is it a sign for something?
