I was looking at pypes systems, they seem to be aluminized.
Does aluminized last as long as stainless?
The x-pipe systems are for cars with headers, or ra manifolds, right?
The x-pipes are of no use with standard exhaust manifolds, right?
I see in the PY catalog they sell RA manifolds for 1964-72(RPE650H),
would these be worth the investment?, and are they easier to install
than headers? Thanks for any replies
