I've decided its time to re-do my exhaust system on my 99 5.2 1500 sport. I think i've decided on Edelbrock Shorties and aMagnaflow high flow cat(or gutt my stock cat). I already have a Magnaflow cat-back exhaust on it with 2.5"(i think?) piping with 3 in' tips. Would this be enough to get the famous deep rumble at idle and the loud sound whenI romp it? Or should I do 3 inch pipes and a different cat-back system? I live in Kansas and there are no annualemissions laws.
