Are we talking about cutting life in half or by 10%?
Cat delete isn't an option for me.
Big +1 for dealing with Alex, great guy.

Cold start is mostly for warming up the primary cats. If you wish to remove cold start with your primary cats in place I would suggest warming up the car for a few minutes prior to driving it. If the temps in your area are very low you can always switch maps (takes about 5-10minutes) and put your cold start back in.
