I had no idea where else to post this. I'm looking at headers for my 99 cobra with a P1. Which is better: Mac or BBk? I'd love to do Bassani or Kooks, but I don't have that kind of skrillah...
I haven't run anything from Mac. Everything from BBK I have used has been decent for the money. I would try and find the headers that have the thickest flanges available and invest in good gaskets.
Just posting my own experience. MAC may be far better than BBK I don't know. If it were me, unless on a max effort car I would go with what ever gave me the least chance of exhaust leaks. Do you have a tube K?
