Description
Large Bore-HD 3.5" 409 Stainless Steel DPF-Back Exhaust System with Black Tip
The Large Bore-HD 3.5" DPF-Back Exhaust System is engineered for Duramax diesel trucks to deliver maximum performance, aggressive styling, and long-lasting durability. Constructed from high-quality 3.5" mandrel-bent 409 stainless steel tubing, this system provides up to a 40% increase in exhaust flow, boosting horsepower, torque, and lowering exhaust gas temperatures (EGTs) for optimized engine efficiency.
Precision Fit & Hassle-Free Installation:
Designed to utilize all factory mounting locations, this exhaust system installs quickly and securely. OE-style bayonet hangers ensure stable pipe positioning under high vibration and extreme heat, while the bayonet tip holds the hanger bushing firmly for an OE-style fit that does not change over time.
Flow & Performance Optimization:
Mandrel-bent tubing and smooth transition bends reduce turbulence and maximize exhaust flow. This precise engineering increases performance and efficiency while maintaining reliable operation in demanding conditions.
Aggressive Black Stainless Steel Tip:
Finishing the system is a bold 5" diameter black stainless steel slash-cut tip with integrated intercooling vents to help reduce tailpipe temperatures. A laser-cut aFe Power badge riveted on the tip adds a distinctive, high-performance visual statement.
Cutting-Edge Design for Duramax Diesel Trucks:
-
Crew Cab / Short Bed (128.3" Wheelbase)
-
Crew Cab / Long Bed (140.5" Wheelbase)
-
Extended Cab / Long Bed (128.3" Wheelbase)
Installation Note:
This system requires cutting behind the DPF unit for proper installation.
Emissions Compliance:
No CARB Executive Order (EO#) is required, making this DPF-back system compliant for off-road and performance applications.
Made in the USA:
All aFe exhaust systems are engineered and manufactured at our Corona, California facility to ensure exceptional quality and performance.
