Product Details
If you're looking to give your 2011-2018 Ram 1500 a serious sound upgrade and a more aggressive look, this Gibson Dual Extreme cat-back exhaust system is a solid choice. Designed specifically for the 5.7L engine, this system exits behind the rear tires at an aggressive angle, giving your truck a bold street presence. It's built to provide a powerful exhaust tone that lets everyone know you mean business, without excessive interior drone.
This system uses mandrel-bent stainless steel tubing for smooth exhaust flow, which Gibson tunes to help improve performance. You can expect a noticeable increase in horsepower, thanks to the Superflow CFT muffler and the overall improved exhaust efficiency. The muffler itself is baffled and chambered, meaning it doesn't rely on internal packing that can break down over time, contributing to its longevity. It comes complete with polished stainless steel slash-cut tips that clamp on, adding a sharp finishing touch.
Installation is straightforward as it's a bolt-on system, meaning no welding is required, and it utilizes factory-style hangers for a secure fit. Gibson backs this system with a Lifetime Limited Warranty, so you can be confident in its durability. If you want an extreme exhaust note and a look to match, this Gibson system is built for that purpose.
