The shipping was fast. The headers were nice and lightweight. Easy to install. My car runs a lot better and faster. Everyday I'm excited to drive my car.

I just got the headers on yesterday. It took about 2 hours - all the holes lined up - life is good! Two of the spark plug boots on the drivers side touch the headers, I covered them with insulation, and I'll be looking for aftermarket wires. Seat of the pants dyno, it feels like I picked up a few ponies, It's to soon to tell if I improved my fuel economy
