Catalytic converter help. ASAP!!
Ok guys so as some of you may know, i am changing my exhaust again. This time for good. I am going to run 2 1/2 inch pipes down from the manifolds to no cats to 18 inch glasspacks and then into 2 1/4 inch pipes and out to 3 1/2 inch tips. With that being said, i am so nervous because i dont know how not having cats will make it perform. I have heard mostly that it wont hurt anything and then i have heard a little that it will get very poor mileage and run horribly. Answers!!
