Well I put a Banks monster cat back exhaust on my 4cyl. TJ and I hate it. I was trying to get something that sounded a little throatier and a little louder. This is way to loud and actually gives me a headache after 15 minutes of driving. So here's the question, can I just replace the muffler with something more quiet? Any suggestions? I can't put the stock exhaust back on because I had to cut it off(it was a bit rusty).
