When you run this open is it bearable at all? I am thinking of installing a cutoff to open on track days but keep it closed as a daily. Is this the 2.25 QTP cutoff?

I would guess it's about the same as open downpipe.

Honestly guys after running open downpipe for a week, I have gotten used to it. I guess I'm going deaf. And people keep telling me from the outside it is not that loud.
