Deep and Throaty
Direct Natural Airflow (DNA) Mufflers are not your ordinary, run-of-the-mill exhaust mufflers. These mufflers are made from 100 percent stainless steel and carry a five-year warranty. They use a new sound diffusion technology to manage the exhaust sound. This new design incorporates stainless steel sound diffusers to bounce the sound energy back on itself for sound cancellation, while maintaining a very high flow rate. Because of these sound diffusers, DNA Mufflers do not use perforated tube or packing, two of the most common causes of premature failure in mufflers. DNA Mufflers are designed for use as an underbody muffler, ideal for the street, truck, and race markets. DNA Mufflers have inlet/outlet sizes from 2-1/4- to 5-inch.

Destroy Your Hearing
Available in 10-, 12- and 15-inch models, the JBL MkII subwoofers handle 3,000, 4,000, and 5,000 watts, peak. The GTi MkII subs are optimized for use in small sealed or vented enclosures-the W15GTi performs flawlessly in a 1-1/2-cubic-foot sealed box, while the W12GTi requires 1 cubic foot and the W10GTi, a mere 0.75 cubic foot. These subs feature all kinds of technical stuff that we will not go over here, but check out the company's website for the full breakdown.

Spark It Up
E3 Spark Plugs deliver an extremely powerful spark, due to the plug's unique DiamondFire Technology. The E3 spark plugs feature a diamond-shaped electrode with an Edge-to-Edge- design. This design delivers forced edge-to-edge spark discharges, which allows a fast flame front to grow unimpeded toward the piston to create a more complete burn of the air/fuel mixture in the cylinder. Backed by a five-year 100,000-mile warranty, they are now available for most pickups.
