From my 2006 ebay auction:
Meet Black Elvis! My 2004 Dodge Ram Hemi 4x4

PERFORMANCE
A.F.E. Cold Air Filter
This replaces the restrictive factory filter, and draws in cold air from outside the engine compartment, giving up to an extra 20 bhp
Gibson Supertruck Performance Exhaust
“Designed for the race enthusiast to give you the deep powerful race truck rumble with impressive acceleration and increased horsepower gains. Designed for hassle free, bolt-on installation. Typical dyno tested horsepower gains average are 10-15 and 15-20lb-ft of increased torque. Fuel economy may improve as your engine becomes more fuel efficient.”
Superchips Programmer Max Horspower gain is 17.8 at the wheels at 3550 RPM
Hellwig Rear Anti-Sway Bar
Reduces body roll so you benefit from better vehicle control.
Greatly improves cornering traction for safer driving and turning capabilities.
These mods have two effects, firstly the performance is absolutely staggering, for a 2.5 ton vehicle, with 0-60 attained in around 7 seconds. I estimate that the engine is now putting out 380-400 bhp. Secondly the sound! You will have to hear this truck to believe it, and in fact you can hear and see it in action, by downloading this .avi video of the truck taken shortly before leaving California.

Sale includes the original factory exhaust and air filter system, and the programmer can also be set to factory settings should you find the awesome power of this truck to hot to handle.
ACCESSORIES
LINEX Spray-in bedliner
Much more attractive and durable than the drop-in liner. Will not distort or crack. And no water can seep in underneath, causing corrosion.
Mopar mudflaps
Official Dodge accessories, featuring the Ram’s head logo.
Set of four stainless steel tie downs. These are retractable hooks, used in conjunction with rope to secure large loads.
WAAG rear bumper guard
Some extra rear end protection, I call this my reversing sensor!
Also, anyone foolish enough to drive into the back of this truck, is going
to regret it!
So, there we are, a truly stunning truck, and a real head turner.
