Header development and design is complex and requires a substantial amount of time and resources to do the job right! Every Doug's header is tuned with the proper tube size and length to efficiently remove all the exhaust from each cylinder, reducing pumping losses resulting in a dramatic increases in horsepower and torque. Doug's headers are carefully developed on the vehicles they are intended to fit and are re-checked numerous times during the design and manufacturing process.

You know you have to have a DC header on your sport compact to really get the most out of your engine's abilities. All the air you can squeeze into the cylinders doesn't make a bit of difference if the burned gasses can't get out efficiently. And guess what: your factory manifold isn't efficient. A DC header, on the other hand, is made up of individual runners heading back to a common collector. Compare that to your stock manifold, which most likely looks like a log that all the cylinders have to dump into. Since each cylinder gets its own individual exhaust pipe on the DC header, you avoid competing exhaust pulses, backpressure, and unequal pressures, all of which can stop the exhaust in its tracks and robbed your engine of precious horsepower. A DC Sports header will ensure that you get the most out of your induction system. There is no mistake with stainless steel used throughout, thick, laser cut flanges, machine welds, and ceramic coating to enhance engine efficency your DC Sports header will help you get the most for a long time to come.

Titanium exhaust wrap, with LR Technology, is made from pulverized lava rock and stranded into a fiber material and is engineered to be stronger than typical wraps on the market today. It has the ability to handle higher heat for improved performance and durability – and with a cool carbon fiber look!

Bully Dog's new ceramic coated exhaust manifolds are the fastest flowing exhaust manifolds in the industry. Designed to provide quicker turbo spool, higher power output and more fuel economy for class 8 engines, these premium manifolds get the job done. Bully Dog's engineering team has spent considerable time analyzing and flow testing various layouts for each manifold, utilizing state of the art CAD design software. Each manifold is simulated and prototyped numerous times as they search for the design that produces the ultimate efficiencies. There are two primary goals they are striving for in the design: first, to maximize the airflow by smoothing out the sharp corners of the stock manifolds and eliminating any bottlenecks in the design and second, to eliminate any known failure points in the stock manifold. The final result is an impressive piece that not only looks great but is fine-tuned in every aspect to improve the performance of the engine.
