Another thing to consider if you plan on tracking your car is that headers and nearly any catback will put you over the decibel limits at many tracks.

The Corsa does not drone. I understand the Borla does not drone either, the rest I imagine have varying levels.

Try pulling the NPP fuse first. You'll really be surprised how often the valves close (even in sport and track). If that's not enough, you've gotta decide whether you want more volume, or a different tone. Also might seem silly, but throw the back seat down if you can. These cars have a ton of sound deadening. They are much louder outside than you'd think from driving inside.

Axleback for sound. Headers will 100% void your warranty.

Agreed. Take some time and put some miles on just to make sure there are no issues with your car that might require some warranty work.

I am going to wait at least a year before doing any mods.
