I have a bone stock GT5S and it even has the cats on it still. Would you guys prefer to leave totally stock or would some opt to take out the cats for improved rumble? I do not have to smog test in Mo. but I do know some states do. If the car got sold down the road, would it be better to sell as 100% as off the line or send the cats in a box with the car? I do like knowing I may have the only 100% original car in the Country but at the end of the day, does it really matter is the question.
