I was at my shop the other day.. I saw an OEM Y-pipe. I asked what it was from and my bro said it was from a later model e46. I'd assume bmw didn't switch for nothing. Either way before you dyno, I want your exhaust just pm me. I was going to make the exhaust you fab'd based on the oem y pipe. IE distance from the headers to the connection. I'm curious to see the distance from the headers to the Y pipe and how you chose that distance!!!
