No one around here even touches Cobra headers. One shop that did broke more sh_t than they fixed. They charged 300 and lost their *ss on the deal.
You should look up what Anderson Ford charges for some of their labor rates. Blowers are ~$1500. We only charged Bo Beuckman Ford $900 to install the Saleen blower for them (on a new car).
