Jetting differences between fmf gold series and ESR pipe?

[Addicted]

I gotta super nice 86 r last night with a full fmf pipe, was wondering can I just switch the esr pipe over without rejetting it?

You'll have to go up a size or 2 at most, which esr pipe you getting?? ATC5???

Just install it and read the plug. If it's lean, go up 3 or 4 sizes.

I keep a ton, maybe 500$ worth of jets on hand (esp when my buddy Jeff hooks me up :beer)

Ya need em..........
