I tried the head pipes from Pypes. The would not ship to CA. so I had them shipped to a friend in Ariz. and picked them up there. The had very nice bends but the flare to manifold wasn’t even close. The flanges were both stamped wrong and would Slide right over the flare. There was no way to use them so I sent them back. The only positive was that they did accept the return. I had some custom made.
