wich headers are $330? i had baught the msds headers like a year ago and i had paid $650 shipping. the labor is what gets you on the headers. i had mine installed at the tire kingdom i was working at. with my discount i only paid $60. regular price would have been around $400. i thinkign of going catless once i put in my superturbo muffler. or having a test pipe made. i think the superturbo muffler should flow pretty good and keep the noise from being super loud with a side pipe.all i have now is a cat resonator and strait pipe to the rear. that is if the muffler will fit in the center tunnel with the heat shield removed. if my measurement are rigth it should fit. where could i find a 2.5 inh tip that isnt rediculously big?
