REMOVING THE CAT

[intake]

on my euro yaris 1.3 2007 i have two cat, one big and another little .
do you think is a good idea to take away the second little cat?

You arent really going to notice any gain at all. The cats are small and hardly that restrictive. If you were to remove one i would remove just both then. To me you are going to sacrifice torque for hardly any noticible horsepower. Your exhaust is going to be annoyingly loud and you are going to turning your low emissions vehicle into a vehicle that pollutes more than a suv
