5" 409 stainless steel constant-diameter DPF-back system with negative backpressure SideKick tip. 85% less backpressure and 15% lower exhaust exit temps than stock, allowing the engine to produce more horsepower. Improves flow and cuts backpressure. Includes Huge Polished Chrome SideKick tip. Banks Power introduces the new 5" 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" mandrel-bent aluminized steel tubing and a massive tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown.With the stock exhaust nozzle measuring 2.85" compared to the Monster Exhaust’s massive 5" 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.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. Duramax owners can choose from two huge 6.5" x 7.5" 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" 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.Shipping Notes

It's different. Not bad, but nothing special.
Color: Navy Melange, Size: XX-Large
The fit is good. I'd say medium weight. It's not quite as light as some of the microfiber pullovers I like to wear playing golf, and not quite as flexible. I'm not sure I like the decorative stitching. The stitching on the shoulders and along the sides makes it look like it's on inside out. Also, the material has kind of a paper feeling to it (for want of a better description). Overall it's decent looking, not a bad fit, not a bad feel, it just doesn't 'wow' me. Unless the price is better than it is now, and already having one, I doubt I'd buy it again.
Most of this is just my own opinion based on personal preference. The overall manufacturing quality seems very good. Someone else might think this is the nicest pullover they own.

Excellent quality and value
This is my 4th Maelreg 1/4 zip shirt. I've lost a lot of weight and looking for clothing that fits well and doesn't feel like a shirt from China. I found that the quality and fit are excellent. The fabric is soft, well made and slightly heavier than other 1/4 zips I've purchased on Amazon. The weight of fabric gives a quality feel. The styles of Maelreg pullovers are great. I get a lot of compliments on these shirts.

MAELREG Clothing Looks Great!
Love this quarter zip. MAELREG makes some comfortable, sharp looking clothing. Their golf apparel is fantastic. The value is worth it. Their shirts are true to size. I am 6', 215lbs and wear an XL, which fits nicely.

Great for Tall Guys
I got this for my husband, he has a pullover that he has worn for years and it needed replacing. Finding one like this that was lightweight and loose fit was a big challenge. He loves the quality and fabric and its not hot but still helps when their is a breeze or chill. I liked that the color and pattern are versatile for all seasons. He is 6'5 and it actually fits his torso! Just get it!

It’s a hit!
Color: Brown Grey Camo, Size: Large
I picked on of these up after seeing it online. I have multiple Maelreg items and all are great quality. They are my go to golf and casual clothing brand. Super comfortable, soft, light weight, and perfect fit. Olive on the east coast and this color is all the rage in the area. These are some of the best value 1/4 zips out there.
