Yea man price should be closer to 5500 USD, I'd look for all the parts myself, stated above, Heck buy some stuff used off here
. One thing make sure is who and when you install the parts THEY better not be charging you to install the HFC's it TP's, those come off to install the headers and the the cat back exhaust has some cross over labor with the HFC's or TP's as well so that should be discounted also.
Tune with ECUTEK, you thank us later
