I installed an ERZ TBE a few months ago. The DP to catback have never really lined up very well. It seems the DP angles up a little and thus there is a gap at the top of the flange between the two. The sound of the exhaust leak makes me everytime i drive the car. No matter how hard I tug and pull, they will not line up. I've kicked around the idea of having a flex pipe welded in, but I only want to do that if I can't get anything else to work. ANY suggestions would help.
