Gibson 14-17 Ram 2500 Big Horn 6.4L 3.5in Cat-Back Single Exhaust - Aluminized

This Gibson cat-back exhaust system is built with 3.5-inch aluminized, mandrel-bent tubing, which helps improve exhaust flow over the stock setup. The system is designed to exit behind the rear tire with a single polished stainless steel slash-cut tip, giving your Ram 2500 a cleaner look. It's a bolt-on installation, meaning no welding is required, and it uses factory-style hangers for a straightforward fit.

The heart of this system is Gibson's Superflow muffler, which is baffled and chambered without internal packing. This design choice is key to its performance, focusing on increasing torque and horsepower in the low-end RPM range, specifically between 1800 and 3000 RPM. Dyno tests show gains of 10-15 horsepower and 15-20 lb-ft of torque, which can make a noticeable difference when you're towing, climbing hills, or just need extra power for passing. Despite its performance focus, Gibson engineered this system to minimize interior drone, so you get an aggressive sound outside without excessive noise inside the cab.

This cat-back system is a solid option if you're looking to get more out of your 6.4L Hemi engine. It comes with all the necessary hardware for installation and is backed by a Lifetime Limited Warranty from Gibson. Remember to check the manufacturer's instructions for any specific details regarding installation or compatibility with other aftermarket parts.
