Hey there, I was just curious. Has anyone used a pair of Doug Thorley's Tri-Y Headers? I know that for my Nova, I need the D-375Ys. I was just wondering if anyone could comment on the quality, fitment, etc of these.

They worth the price? I know they only come in a 2.5" collector for my car, but the flow pretty well right?

What do they sound like open header? I got a pair of cutouts layin' around
