Its to lare for me to go back and put the original cats on! Is not about buying or using the old ones period. Its jst not an option, Emissions here is not an issue but loud and disturbing car exhuast is!! I ask you guys cuz maybe someone here has done it also and I need an idea of what I should get. Now if there is no possible way that the car will sound decent without the original cats? Then I would have to go back and do it all over again and install the right parts in order to ge it to sound right.
