Thats a lot i wasnt thinking about putting all my money down on them. How much horsepower/torque gains would i get out of a set up like that and how are the mac headers zstang?
you wont get a lot of power out of them, especially for the money. I mainly put them in because of the supercharger, otherwise I would have left the stockers.
But the Macs are holding up very well after 2 years.
Melo let me know what you think about the jba when ya get them installed. I have no clue what to get right now. I havent found too much information on anything yet.
