Thanks for all the input below !
Looks like I'll follow KLR142's advice and buy the st.st. system ready made. I'll check out diameter and mandrel bend issue and let y'all know.
Why is there one pipe listed for 140 -1973 and another one listed for 1974? Is this because 1974 was the FI B20F and has a different exhaust manifold? Wasn't the FI B20E available in '72-73?
Reason I ask is that I want to get a stock B20E or B20F exhaust manifold for the front end of my system. (I don't want the B20B manifold with the intake heater business, and I've had really poor luck with two different headers -both I think were from IPD.)
When I go to procure the FI-type exhaust manifold for my 70 145S B20B, what years and/or engine types should I be asking for? I also hope to avoid EGR fittings and don't know if these were ever part of the B20 family exhaust systems.
Much appreciate all your help !
Later, Al
