I had all the exhaust components off of my car so I figured it'd be a good time to go through everything and make a guide for those that are in the market for new exhaust parts. What's your favorite exhaust modification you've done?

Recently installed Tomei UEL headers, and have a Greddy EVO GT catback - looking to maybe get a little more loud out of it but I'd really like to reduce the drone around the 3k RPM mark .. what would you say is the best way to go about it?
