i have a question about my exhaust. i know the car has a primary cat and then 2 precats on each exhaust manifold with 02 sensors. my question is, if i put a straight pipe and delete the primary car will i get a check engine light? there is no 02 sensor on this cat, im just trying to give the car a little more of a rumble and make it sound a tad better, i am deleting the resonator. any input would be great. thanks.
