Just installed MF 12909. Love it! But...

I ordered my Magnaflow 12909 off Amazon with 2 3.5" clamps. 2 cuts, 2 clamps. Easy right? Not so much.

I got the muffler cut out really easy. Clamping in the inlet was really easy.

As it turns out, the pipe diameter of the butterfly valve is smaller than 3.5". More reason to just remove it completely, right?

So my question now becomes: what's the diameter after the butterfly valve? Can I just get a piece of 3.5" pipe? Or will I need a reducer?

Basically, what's the diameter of the green line? Looks like 3.5" but wanted to know of any gotchas.

Thanks! Looks like the answer is 3.5"
