I have a 99 Ford F250 super duty with a 5.4L engine. I put a 2 1/2 glass pack muffler on it but kept the stock pipe on it. its kinda loud but not as loud as my old truck which had a cherry bomb. Should i keep the glass pack and give it time to get loud or put just a straight pipe on it? I've heard that it will sound loud and good. But i have also heard it would sound bad. I don't know what to do.
