Compared to the typical, crush-bent exhaust systems, a mandrel bend exhaust system offers superior performance, greater durability, and an elevated aesthetic. Basically, the crush bending creates a crimp or pinch in the pipe in order to form a bend, where the mandrel bending process ensures a smooth, consistent diameter from end to end. This maximizes exhaust flow for optimal engine efficiency and power. But improved performance is just the beginning of what there is to be gained through upgrading to a custom mandrel bent exhaust.
Mandrel bending can be customized to achieve several different objectives. Your new system can be tailored to enhance vehicle performance, while further customization can fine-tune the sound of your engine and your vehicle’s overall look.
STEP 1: Identify Your Objectives for Your Mandrel Bend Exhaust System
It is important to be clear on what you want from your custom mandrel exhaust system; are you more interested in increasing horsepower, hitting a distinct exhaust note or getting an upgraded look. For performance, focus on optimizing flow and reducing backpressure. For sound, select mufflers or resonators that match your desired tone, from aggressive growls to refined purrs.
STEP 2: Select the Right Material
Mandrel bent exhaust systems are typically made from aluminized steel or stainless steel. Aluminized steel is cost-effective and resistant to corrosion, making it the popular choice for general use. Stainless steel, on the other hand, offers exceptional durability and corrosion resistance, making it ideal for high-performance or off-roading in harsh environments. In our facility, we have the highest quality of supplies.
STEP 3: Choose the Correct Diameter
Pipe diameter plays a significant role in exhaust performance. Smaller diameters increase exhaust velocity, which is ideal for low-end torque, while larger diameters reduce back pressure, enhancing high-end power. Match the diameter to your engine’s displacement and intended use to achieve the best balance of power and efficiency.
STEP 4: Design Your Mandrel Bend Exhaust System Layout
Mandrel bending allows for more creativity in exhaust layout. You can consider rerouting your exhaust and even changing it from a single to a double, or vice-versa. Even with tight clearances, rerouting can result in improved flow with the precise, smooth curves that mandrel bending provides.
Things to Keep in Mind
Key Components
Your exhaust system can incorporate some distinct parts that affect performance, sound, and appearance. Don’t forget to weigh in on your preferences for:
Header: Include a header to improve exhaust scavenging and enhance performance.
Catalytic Converter: Ensure compliance with emissions standards while maintaining flow with a catalytic converter.
Mufflers and Resonators: Tailor the sound profile of your exhaust.
Exhaust tips: Add a touch of finesse with polished chrome or black-coated finishes.
Work with a Professional
The mandrel bending process is an exercise in precision requiring trained technicians. Ensure perfect fitment and optimal performance from your custom mandrel bent exhaust system when you have it designed and produced by an established fabricator like The Expandit Company (TEC).
