Monster Sport™ Diesel Exhaust System by Banks®. Add power and rumble to your diesel with this cat-back exhaust system at a moderate price. With a 7" Monster Muffler, and all mandrel-bent stainless steel tubing, you’ll more than double your flow capacity and add that authoritative rumble the factory system keeps inside.

Banks VideosBanks Exhaust SystemsBanks About


  • 4" constant-diameter cat-back exhaust system
  • Virtually eliminates backpressure and more than doubles flow!
  • Lowers exhaust gas temps
  • Straight-through Monster Muffler delivers a throaty exhaust note
  • 100% Stainless Steel
  • Easy installation
  • Fully compatible with the factory warranty
  • 5-Year Limited Warranty

Remove the restriction to power and torque that the restrictive OEM exhaust system has saddled you with. This system uses stainless steel tubing that's mandrel-bent for a constant cross section - even in the curved section of the pipe. Reduced back pressure means better cylinder scavenging, increased cylinder filing and more power. At the same time, reduced back pressure means improved fuel economy, because you use less throttle to go the same speed. You're not paying for fuel that is used to push spent exhaust gases through a restrictive bunch of undersized pipes with constricted, restrictive bends.

Banks - Monster Sport Siesel Exhaust Systems

The 7" Monster muffler's straight-through design has essentially zero resistance to flow, but still keeps the neighbors happy. The expansion-chamber design eliminates freeway drone keeping the driver and passengers happy at the same time. With 4" inlet and outlet, the Monster muffler has a high-temperature ceramic packing that will far outlast the fiberglass used in many aftermarket mufflers. Even though this muffler is slightly smaller in diameter than the 8.5" Monster muffler, the core is still a full 4" diameter, straight through for maximum exhaust flow.

This no-frills exhaust system still delivers solid performance at a reasonable price. It's made from the same materials and with the same attention to engineering and fabrication detail as all the Banks exhaust systems, and carries the same 5-year limited warranty. All hardware is included.

Banks® Exhaust Systems are US-made, each unit is precisely dyno-tuned and shaped to fit selected model and production year vehicle and deliver great increase in torque and horsepower. Even the polished muffler tip is built with T-304 premium stainless steel. Each exhaust system has an easy bolt-on installation and requires no modifications to the vehicle for the installation.

Banks Exhausts System
Wow is what I say about Banks exhaust it was so easy to hook up. I read through the info a couple times and got to work. From start to finish 2hrs time I had my exhaust off and the Banks on and ready to drive down the road! Everything that I've purchased from CARiD so far has been excellent! I'm very glad that I found them and very happy that I chose Banks Exhaust system. Sincerely, Otis.

From Good To Great
Ordered the Banks 48789 Monster Sport Diesel Cat Back for my 2003 Ford F-250. The previous exhaust was stock, and was good - but only that. I was sure there was something I could do to get more power, better acceleration, and a better engine sound that still let me know I drive a diesel, but didn't get ugly stares from noise sensitive neighbors. Banks took it from good to great and the advice I got from Greg at CARiD was great as well. Like, like, like it - and so do the neighbors. Thanks!
