I'm about to do a dyno comparison and will post my results in the Dyno Section of the forum. I'll be going from 1-3/4" FLP headers with a 3" true dual exhaust to 1-7/8" ARH headers with a 3" ORY into a 4" intermediary and then to a 4" Mufflex.
I made the leap because I now have a 383 stroker and felt that I could gain 5 to 10 rwhp from the bigger primaries. I went with ARH because of the stainless steel design and the merge collectors. I will be very disappointed if I don't gain anything. I was really hoping for at least a tenth and 1 mph out of these headers. My car is very consistent and I dead hook almost every pass so any gains will be real. Last time at the drag strip with the FLP headers I ran 10.27, 10.28, 10.30, 10.31 and 10.33. Looking to go 10.17 or better with the bigger headers.
