While on the horsepower side, 9 hp may not seem like much, 27 lb-ft of torque is substantial for an after-cat system. Also keep in mind that the stock system is basically a 3-inch mandrel-bent setup, which doesn't leave a lot on the table in terms of power gains.
Best of all, the truck has an incredible sound, and the dual-exit rear system looks awesome poking out from under the full steel roll pan. If you're in the market for some cool duals for your Dodge, check into B&B's new stainless system for the Hemi Ram.
Better Breathing Since we opened up things on the exhaust side of the Hemi, it was only fitting that we improved the breathing on the intake side of the system as well. The easiest way to improve intake airflow is through the installation of a performance air filter.
The folks at Airaid Performance Filters in Scottsdale, Arizona, were only too happy to give us one of their new drop-in replacement filters for the Hemi. Airaid Premium Filters use 4+1 SynthaFlow filter technology for improved filtration and improved airflow compared with the stock paper element.
On the dyno, the filter alone was good for an additional 3 hp. Installation is a simple R&R deal anyone can accomplish.
