JBA Equipped 04 Lil' Hemi Express by Profinish-Proglass

"Hemi." Say the word around any true hot rodder and they will know your talking about an American V8 powered Mopar. When Dodge introduced the 5.7L Hemi in the 2003 Dodge Ram, Chevy and Ford truck owners took notice. This is a serious player in the extremely competitive truck market. JBA didn't waste any time in getting a development program started for the Hemi as soon as they hit the streets. The result was the most complete and powerful exhaust package on the market. JBA Cat4ward® Headers with big 1-5/8" primary tubes, high flow Y-pipes, and a 3" tuned exhaust systems. Each one is as tough as the truck it was designed for. These performance matched components can be installed on their own or as a complete system for maximum performance, efficiency and mileage.

There is no mistaking that the 5.7L Hemi has first class power in the truck and SUV market. JBA's new Cat4ward® Headers for this awesome power plant have been engineered to deliver more of that power throughout the RPM range where it can be put to good use. Any truck owner can tell you that low-end torque comes in handy when hauling or cruising. Mid-range power when charging a hill or passing on the freeway rates high on the wish list too. JBA addressed both of these areas and added an extra 15+ hp to the peak power as well. How does an extra 24 lb-ft. @ 2100 RPM sound? You have plenty of options to suit your needs as well - "works" finish stainless steel or high heat rated ceramic coated. To learn more about these finishes Click here.

JBA High Flow Y-pipe::

Looking for a little more power? Upgrade your factory Y-pipe to a high flowing JBA Y-pipe. Unlike the crushed tube merge on the factory set-up, JBA's performance Y-design gives a smooth high velocity transition that greatly reduces turbulence and back pressure. It features mandrel-bent tubing that transitions into a large 2-3/4" exit. This Y-pipe is an inexpensive upgrade that can be added to a stock vehicle or in conjunction with JBA Headers and Exhaust.
