Product Details
Starting with the stainless steel mandrel-bent tubing, this Gibson Super Truck cat-back exhaust system is built to last on your 2003 Dodge Ram 1500 SLT with the 5.7L engine. It's designed to give your truck a serious performance upgrade, featuring dual tailpipes that exit in front of the rear wheels, capped off with stainless steel tips. You'll notice a distinct, aggressive sound that’s often described as a race rumble, but Gibson has worked to minimize interior drone so it’s not overwhelming on the highway.
Underneath, the Superflow™ muffler uses a baffled/chambered design without internal packing, which helps it breathe better than the stock system. This improved flow can lead to noticeable gains in acceleration and horsepower, with typical dyno tests showing an average increase of 10-15 horsepower and 15-20 lb-ft of torque. Installation is straightforward thanks to the bolt-on design, meaning no welding is required, and it comes with a lifetime limited warranty for peace of mind.
While this system is built for performance and sound, it's not recommended for towing applications, and the noise level may exceed 95 decibels. If you're looking to give your Ram 1500 a more powerful voice and a bit more pep in its step, this Gibson exhaust is a solid option.
