Hi All,
I have a top mount single turbo and got a custom 3.5'' single exhaust installed,So my question is that the exhaust has no give,there is a flex pipe and one solid mounted hanger.wondering on is there expansion when the exhaust heats up and no give going towards the back of car,the flex pipe is more for side to side give since its on the run part of the exhaust.
