I WAS JUST WONDERING IF A GSL-SE COULD PAAS EMISSIONS WITH A HEADER CONNECTED TO A HI-FLOW CAT? ALSO, WHAT TYPE OF POWER INCREASE SHOULD I EXPECT WITH THIS SETUP. THE MOTOR HAS 20K MILES ON IT. THANKS FOR THE HELP

 

It passes emission with flying colors. My car with header and high-flow cat has better numbers than with stock system.

You can definitly feel the extra power in acceleration. Also the car seems to be running cooler.

It's one of the most important mods for a GSL-SE, the engine can actually breath by removing that huge manifold and the pre-cats and the main cat.

 

Did somebody say E M I S S I O N S??????????
