Product Details
You're getting a complete cat-back dual exhaust system from Gibson, designed specifically for your 2003 Dodge Ram 1500 SLT with the 5.7L engine. This kit includes the necessary stainless steel tubing, the Superflow muffler, and polished stainless steel slash-cut dual tips that exit straight out the back of your truck. It's built to replace your factory exhaust from the catalytic converter back, giving your Ram a more aggressive look and a throaty sound.
Gibson's Superflow muffler uses a baffled and chambered design without internal packing, which helps reduce backpressure. This means your engine can breathe a little easier, potentially leading to improved torque and horsepower. You'll notice a more aggressive sound, especially under load, but Gibson has worked to minimize interior drone so it's not overwhelming on the highway. The tubing itself is made from stainless steel and is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. Installation is designed to be a hassle-free bolt-on process, meaning no welding is required, making it a straightforward upgrade for many DIYers.
This system is designed to work with most bumpers, roll pans, and trailer hitches, offering good compatibility with common rear-end accessories. Gibson backs this exhaust system with a Lifetime Limited Warranty, giving you confidence in its durability and performance for years to come.
