[Equinox] Install: GTM 3" Cat-back Exhaust

Stupid question:

The pics don't show how the catback matches to the catalytic converters... I'm assuming theres no issues where the catback goes from stock size to 3"? Does it taper down to match the stock cats? Do you have a pic of it?

I bought two extra flanges and cut the flanges off the cats and welded them on while I am in between systems

I often have wondered why companies choose not to make 3" exhausts all the time... I always thought that bigger meant it would breathe better... perhaps it has something to do with backpressure, but oh well.
