Anyone else running these pipes?
I am using the recommended setup from SLP, but i gutted the air box, reed stopper notch, thin head gasket.
I am getting a little popping off idle when running it on a stand in the garage.
Seems like a lean condition.
I am using 45 pilots, anyone else using something different?

Call the guys at slp they will tell you what you need to know. 45 seems super lean to me. I have power inc center dumps(way milder pipe than slps) with no additional mods and am using a 45 with 2 turns of fuel screw which seems lean to me(laggy) and idles high but doesn’t backfire. I’m gonna go up to 47.5s. I would imagine those pipes and mods would require a lot more. I’m still trying to get more info on my pipes lol good luck
