hi all...

as we all would know our spectra/ceratos have catalytic converter mufflers.

im planning to change that to a sports muffler.

does anyone know if this will affect my engine, exhaust, vehicle etc in a bad way or a good way..

as catalytic converters are good for vechicles but is it worth changing ?
