My buddy at school has a wrangler with a 4.0, he was on in place of his muffler, so no muffler...Man it sounds baddddd. He has his regular exhaust pipe welded to one exit and just keeps the open exit on the valve open all the time
....I wonder if i could run that setup?? I guess its the same as having not muffler and just dumping it....Though if i installed it after or before my muffler itd be ok right? Anyone got one of these?
