Full Length,or shorty?
here's a question i was reading up in one my mags, it said that the full length headers add 16-25 hp, would after market shorty headers make about the same?i like the sound of the full length headers but I also have shorty headers on my 94 cobra pace car motor, so i was just wondering if anyone would happen to know. i mean after all they both are doing the same purpose making the car exhaust the air out better with wide pipes
