I want to do a whole new exhaust system, that will boost performance, and not be too loud. What are your recommendations starting from the headers?

Performance.. stock GTS 5S-FE engine? Stay stock yo.

yeah prettymuch anything you do to the exhaust system is going to make it louder, if you really feel the need to change something under there, the manifold would do very well to be replaced by a stock 3sge exhaust manifold. It's tubular designed not cast like your stock one.

wht about for a 3sgte running a little above stock boost? 3 inch will make turbo spool up faster but will it loose power due to low back pressure? is it needed?

yea i have a gts, so changing the exhaust does nothing for the performance of these cars? other that the headers of course
