My jba catback came ups yesterday and the box was damaged bad and looked to be taped up by the shipper. My question is what does the jba muffler look like is it oval or round? The one I got is oval 22" long and with a dent or two and also scratched up from not being wrapped. I thought the jba was a round muffler. The muffler I got has not one marking or number on it. I have a call in to jba bit no response yet. Just want to make sure im not being ripped off.
