  8. Stainless Power headers bad fitment - is this safe??

    My car just got the Stainless Power headers installed (part number SM15H3CATLG) and the shop said that the fitment is very bad, there is only a couple of millimeters space between the headers and the frame of the car, is this normal?
  9. Headers install cost?

    Just bought headers and I know it’s a pain on jack stands but has anyone from Alabama, Mississippi, Tennessee, or Arkansas paid a shop to do it? Trying to figure out prices near me and if you reccomend someone. I would rather do it myself but not having a lift close to me makes things difficult.

    I know you can wrap your headers for performance gains and it will also reduce the amount of heat they produce into your engine bay, but by how much? By how much should I expect the intake air temps to drop (I have an exposed cold air intake) if I wrap my headers?
