Just bought a mk1 Yaris 1.3L, what are my suspension choices?

[Dizplay]

Hi! I just bought a 1.3L Mk1 Yaris in green as a daily, I'm totally new to Toyotas but I've had a few euro daily drivers similar to the Yaris.

My general approach when I get a new daily is to make more low and firm suspension and louder exhaust, then wheels, then ICE... all on a budget of course :P

So what are the standard choices for stiff lowering springs on the mk1 Yaris? As it is a daily, I dont want to take TOO much off the ride hide, it still has to be drivable.

Next thing will be the exhaust, what is the diameter of the pipe just after the cat? Need to decide if I'm doing a custom or bolt-on exhaust, again what are my options for bolt-on cat back exhausts?
