Ok im having a STS rear mount turbo set up for my car put on and im wondering what the exhaust will sound like when it gets done. I know its going to be loud and thats cool but i have mac headers, ory pipe, and loudmouth into the turbo and 3 inch piping from the turbo to the tip and the tip is a dual that has a 3 inch inlet and 2 3inch outlets and it will be placed in the middle of my car. How much do you think this will help my turbo spool, cause i was thinking it will help out alot more than a stock exhaust cause the more air flowing the better it will spool right? If that gets to loud i will just replace it will gmmg exhaust.
