mac headers and off road y-pipe?
What kind of power gain do you get from mac headers and off road y-pipe? my car is lowered and i think long tubes are just to low,so the the next best thing is mids right? just wondering what kind of power increase i'll be looking at?

i'm guessing it's not typical, but i went from a 13.1 at 107 to a 12.5 at 112 switching from stock manifolds and a glasspack to macs and dual cutouts.......i went with the macs for clearance as well.....
