I installed my Thunder Header yesterday and noticed 2 springs to put on. I installed the down pipe with the springs and it sounded like a truck (there was a big ass leak). I took them out and just directly bolted it with out the springs. What were those springs for? were they supposed to be used to reduce vibration since the stock flex pipe also had a big ass spring?
