NIce! That ESR pulls alot more on top than the Fatboy. Did you do A/F on these tests?

What is the "type 46". I only see a type 6, midrange, Eliminator, and hi-rev on their website.

It's an old hand made pipe, back from 1991. The replacement for this pipe was the eliminator as they couldn't get the manufacturer to make enough.

Well $h!t, I'm running the eliminator. Looks like I'll be switching pipes.

I saw a video of some tuning with a a/f gizmo. had yellow green and red light bar to tell if the mixture was on. anyone know what that was? Sorry to jump into thread but have been wondering who made it.
