Will i see a increase going from EMI thumpers to a good header on a 292 with 502s worked.What is a trouble free header out there.Thanks for your opinion>>>>

No! I went from stainless marines to Eickert Headers and saw no increase in speed. The sound was a lot better but not for the extra money it costs! What kind of speed are you getting now, how much HP do you think you have?

I have 502s bored out,cam,merlin intake,800 holley,EMI, bravo 4 26" trimmed all out about 5200 rpm seen between 77-80 in the past.Put Zoomers mufflers on getting about 76 this summer.The mufflers have pin wheels that spin the exhaust.I am sure it made some back pressure.Thanks for your .02 ...

I love that thing, love that imron design and love the non typical red

Thanks! It one of the few Formula Imron designs from that era that still look good today IMO!
