FAQ
Is T304 stainless worth it over aluminized?
Yes—T304 offers superior corrosion resistance (salt, moisture, road grime) and is best for long-term builds in harsh climates.
Will this fit my specific truck?
This is a universal 3.0" mandrel bend. It’s not vehicle-specific; measure your system and plan your cuts to suit your routing.
Can I clamp it or do I need to weld?
Either works. Welding provides the cleanest, most durable result. High-quality band clamps can be used where serviceability is desired.
What other bends should I consider for complex routing?
Pair MB1021 with MBRP 3" 90° and various 4" or 3.5" bends listed above to fine-tune your path while keeping flow smooth.
