How would the stock exhaust compare to a APEXi GT Spec w/ the silencer installed

(also with an SP downpipe)

The reason why Im asking is becuase I was having a hard time hitting full boost, but I kinda remember that I would easly hit high boost at the lowest setting when the silencer was out..

thanks!

The silencer is going to be a very big restriction, no matter how much you can flow through the exhaust. Blow into a big diameter straw with a small, pin-size opening at the end and you will notice your face getting red. Harder to blow the same amount air than a big opening.

ya.. I tested my theory this morning... hit full boost very easly..
