Aesthetics and function. That’s what you get with aFe’s Large Bore-HD 4” 409 Stainless Steel DPF-Back Exhaust system for your GM Duramax.

Single To Dual Exhaust Conversion:

This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

Simple Installation:

All systems use factory mounting locations providing stability and hassle-free installation.

OE Fit:

OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.

Flow and Performance:

This Large Bore-HD exhaust system is constructed of 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

OPTIONS:
  • 6” Massive Polished Tips: Dual high luster, polished 304 stainless steel slash-cut tips. The tips feature a drain port on the bottom to keep rust and corrosion away.

Its a hit for my 9lb chewer!
Style: Chilly Penguin, Size: Small (Pack of 1)
So far so good! My Pup is a chewer and destroys most of his toys. This has been great to keep him happy and occupied for about an hour. I work from home, so when I know I need to keep him busy this is perfect. Ill keep an eye on it to make sure he doesn't break it, but it is pretty solid and thick. He can get through a puzzle in seconds, so this has been so good for him. Ive done mostly broth and veggies, some kibble. Even yogurt and peanut butter. Right now he gets it twice a day. He spends about an hour with it and then hes so tired hes ready for a nap. Once around mid day and another late evening before bed. Im ordering another to keep for when I have to leave him home alone. He cleans it pretty well, but Ive found soaking in hot water also loosens any bits left behind. Because its small, I'm not worried about extra calories.

SMELLS MUSTY
Opened it up for our pup on his bday and it smelled like pure mold. We had to throw it out because it was just terrible smelling and we didn't want our pup to even put it in his mouth!

WORTH IT!
My English Bulldog could chew through any toy even if it was advertised not to be destroyed. This was the only interactive toy that he was not able to destroy. YEA!
