Banks Power introduces the new 5 inch Monster Exhaust designed specifically for the 2017-2019 GM 6.6L Duramax L5P 2500/3500 HD pickup trucks. The DPF-back exhaust system features constant-diameter 5 inch mandrel-bent aluminized steel tubing and a massive patented tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown.

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 percent greater flow area than stock. The Monster Exhaust boasts 85 percent less backpressure than stock, leading to more power and increased fuel economy.

The Monster Exhaust also provides a 15 percent reduction in exhaust temperature two feet behind the tip during regen. The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through a process called 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, reported by many Duramax owners.

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 matte black. And, unlike other brands, Banks' chrome-plated stainless tip will not turn brown with heat.

The Banks 5 inch Monster Exhaust (Part No. 48996 for chrome or 48996-B for black) fits all regular cab short bed, double cab short bed, double cab long bed, crew cab short bed, crew cab long bed, and dually models.

XL was way too big for me
Size: X-Large, Color: Black
Jacket is flashy and made better than I expected. I'm 6ft 1in, 215lbs with a 45" chest and I was swimming in the XL. Sleeves were too long for me and I have long arms. I've ordered the next size down and hope they give a refund on this size for me.

Insanely small
Size: 3X-Large, Color: Golden
The jacket is well made and seems to hold the sequins well. However it runs very, very small. I am 6’1” 280lbs, I wear a 2XL shirt comfortably and the 3XL shirt I have I’m swimming in. I bought a 3XL because I read it ran small. However I can barely get this on. I’d say this 3XL jacket is probably a regular Large, MAYBE an XL.

Perfect for the occasion
Size: Small, Color: Purple
Fit was great and true to size. I am 5'6" 140 lbs. and wear 38S jacket. Ordered a small. Bought this for a "Prom" theme party. Everyone commented on it. It's not a high quality garment. But for something like new years eve party or a night out in Vegas it's perfect.
