Looking for a way to take your Cummins truck to the next level? Check out the Banks Power 49778 5 Inch Single Monster Exhaust System. This system virtually eliminates backpressure after the DPF, and features constant-diameter 5" mandrel-bent aluminized steel tubing. This means less backpressure than stock, and more power for you. Plus, it comes with a huge patented 6.5" x 7.5" ob-round slash-cut exhaust tip in chrome-plated stainless steel that will not turn brown with heat. If you're serious about performance, this is the exhaust system for you.
