The DC Sports 4-2-1 header for the 420a engine is a great product. 300 Shipped, from
www.ultrarev.com. A stylish ceramic coated design and long runners, which have a gradual bend at the down pipe for maximum flow with great flanges make the appearance remarkably sexy under the hood. Installation takes no more then an hour, and with a good exhaust manifold gasket leaks are non-existant.
Coming with the product is an O2 Sensor wire heat shield; which fell off after about Ten miles due to poor adhesive backing; also two stylish DC Sports Widow Stickers are bundled for those of us who choose to advertise for the company.
Performance of the Header is amazing in the area of torque, and slightly less thrilling in the area of horsepower. However, when used with a high flowing cat, and cat back the sound is pure bliss. A must buy for those who are considering it.
