Shipped out same day and got to me quick. The packaging was robust, and the part was protected. Customer service was top-notch when I called with a quick question about torque specs.

This thing bolted right up, no issues at all. My buddy helped me and said it was one of the easier ones he's done. Way better than dealing with that old rusty pipe.
