Have you noticed the factory exhaust outlet on your L5P Duramax? The stock exhaust nozzle measures a measly 2.85" that drastically reduces exhaust flow right at the tailpipe. Upgrade your system with this 5" DPF (Diesel Particulate Filter) Back system from Banks, available in either a polished or black exhaust tip.
UP THE FLOW
With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhaust's massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock. The Monster Exhaust boasts 85% less backpressure than stock, leading to more power and increased fuel economy.
CHANGE YOUR LOOK
Duramax owners can choose from two huge patented 6.5 x 7.5-inch ob-round slash-cut exhaust tips: chrome-plated polished stainless steel or high-temp Cerakote matte black. And, unlike other brands, Banks's Cerakote black tip will not turn brown with heat.
DROP THAT HEAT
The Monster Exhaust also provides a 15% reduction in exhaust temperature two feet behind the tip during regen! The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving. Unlike the stock Duramax exhaust, which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck. This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by many Duramax owners.

The sheet is too short for my liking
Color: Heather Grey(flat Sheet Only), Size: King
This king sized top sheet wasn’t quite long enough for a good tuck-in. Can’t comment on wearability because I won’t be using it. Did not return because I had washed it

Warm and Soft
Color: Solid Forest Green(flat Sheet Only), Size: King
I wanted a sheet that felt warm in the cold weather. Upon reviewing several other sheets, I took a chance on this type. I’m happy I did, no more cold feet in bed! It washes and dries (on low temp.) very well too.
