Hi my fellow G owners!!!!! I'm new to the site and have a question. I have a 2003 G35 Coupe auto and the only mods is a Z1 Motorsports Intake and Plenum. I love the sound of the stock exhaust and don't won't to change it, but was going to get high flow catalytic and Osiris Engine tune. So my question is would it be worth it to get the high flow cats and tune, if I plan to keep the stock exhaust.
