Re: Have Stepped Headers Been Proven Out ?
The merge collectors needed a different fuel curve to get as good as I could get them, but still down from straight 3 1/2" collectors. My friend Pete Peery found no gains, last I heard, from merge collectors on his LT1 SS GT car. Some engine love them. I even pulled some exhaust duration trying to make them work. I only run 4 degrees split with the straight collectors.
