This exhaust system isn’t called “Monster” just to sound cool. That’s because the Banks’ Monster® Exhaust is a meticulously designed & tested system that actually delivers cooler exhaust gas temperatures. Cooler EGT equals power. This 4" rugged, heavy-duty 100% stainless steel Monster of an exhaust system cuts backpressure by up to 98% — that’s almost NO backpressure! With air-flows up to 176% better than your Duramax’s stock exhaust, Banks Monster exhaust system is streamlined with heavy-wall tubing and constant-diameter bends — maximizing your truck’s airflow.

Key Features

  • Extensively tested & validated
  • Improves flow up to 176% — virtually no backpressure
  • 100% stainless steel — no aluminum here!
  • Giant 5" polished rolled-edge tip
  • Muffler’s expansion chamber cuts obnoxious noise
  • Won’t void factory warranty
  • Lifetime Limited Warranty

With a name like Monster you might think the Banks Monster exhaust system obnoxiously over-powers in-cab conversations and music — not so. Unlike the noisy drone of many straight-through mufflers, this Monster’s muffler is extensively sound-tested and engineered with a unique expansion chamber and spun ceramic, a very high-temperature packing. The result? A rich, authoritative exhaust note that isn’t domineering — yet it more than triples the stock muffler’s flow! Now that’s a Monster!


How would you finish off this expertly engineered Monster? Banks has crowned their Monster exhaust system with a 5" rolled edged tailpipe of polished-stainless steel. It’s double-walled design features a 1/2" air gap — preventing heat from tarnishing its mirror finish. This Monster’s crown adjusts with a clamp, letting you decide its position on the tailpipe. All considered, the 4" Banks’ Monster is one cool exhaust system.
