Ditch the cat since you are in manila, if your esi is really equipped with it.

If your car is EFI and still has the cat, yeah, you can ditch that... as long as the car is in good condition, it'll still pass emissions with flying colors. If it doesn't, don't throw that cat away yet.

If im going to ditch that cat out does my car would become noisy?? Will it gain torque or hp??
