If you are like many new Chevy Silverado HD & GMC Sierra HD owners, you’re looking for options and ways to upgrade the look and sound of your new diesel. May we suggest for your 2011-2012 Duramax 6.6L LML exhaust the new performance diesel exhaust system from Gale Banks Engineering. Banks Monster Exhaust systems are 100% stainless steel and streamlined with heavy-wall tubing and constant-diameter bends. Finished off with Banks’ proprietary CoolCuff exhaust tip technology, this is a meticulously designed & tested DPF-back system that actually delivers cooler diesel exhaust gas temperatures. It also cuts back pressure by up to 57% and has air-flows up to 80% better than your stock Duramax exhaust. And of course no Banks Monster Exhaust or Banks Monster Sport Exhaust would be complete without an impressive 6″ rolled edge polished-stainless steel tailpipe. It’s double-walled design features a 1/2″ air gap preventing heat from tarnishing its mirror finish. The 4″ Banks Monster exhaust sounds great too, with that proven deep aggressive exhaust note diesel enthusiasts crave.
