I am going to my fabrication guy tomorrow because I have grown somewhat tired of the sound from my 44mm wastegate and dump tube. I will be converting to a recirculating down pipe. My question is if anyone has recommendations as to how and where the piping should be welded. I am confident in my fabricators work, however I always find it helpful to have suggestions from those who have had experience with the same work. I have done some searching on various forums and I've found that it seems the tubing should come in around 18" back from the turbo but what I could not find is where exactly on the down pipe it should be welded in. I can imagine that if done incorrectly it could disrupt the flow of exhaust gases. If anyone has any pictures or advice on the situation I would greatly appreciate it.
