High Flow 2 Barrels.
If you have a 600+ inch motor this might be for you. I don't have anything big enough to test it and don't trust my flow bench at this much flow to put a number on it. If you're interested in trying it out, I'll offer a 60 day return less shipping. I'll throw in the customary CPR shirt and add a CPR zip up hoodie to say thanks for testing it.
