OK..And i did do a search btw. But to my knowledge.. the turbo outlet pipe is referred by as many names... turbo elbow, turbo extension. and the outlet pipe.. well heres my question... some come with 2 piping one for the and one for the wastegate gases to come out into the atmosphere.. Well.. is there any pros and cons about having 2 piping and just having 1 outlet piping.. I also.. some come in 70mm and 80mm and was wondering which one would be a better fit to a 3in dp.. cant do translations that well so i wouldnt know if 80mm was = to 3in... im dumb

But anyhow... your imputs are valued.. thanks
