Countless hours of research and development went into the creation of this header. The change in the design of the factory exhaust system presented a new set of challenges for DC Sports engineers.

With the stock catalytic converter welded to the secondary, the R and D Department had to find a way to create power out of the primary only. Computer aided design and extensive dyno testing led to our successful collector design. The result of our labor is a header that works with the factory secondary to produce power throughout the RPM range.

Great look, sound, with tiny but good gains!

By Anthony Wilkerson on 7/15/2011

For the base it is mostly just a looks item, however, performance wise it does get you those decent gains especially combined with CAI and a better exhaust. If not for speed just the elimination of more back pressure helps with gas mileage! Do not get if you use a SRI the heat soak will increase with this, and please don't wrap it if you value the warranty.
