FAQ
Is MB2017 vehicle-specific?
No—MB2017 is a universal 4" mandrel bend for custom fabrication. Measure your space and plan your joints (clamps or welds) before ordering.
What material is this and how does it hold up?
Armor Lite (aluminized steel) resists corrosion well in most climates and keeps cost down. For harsher environments, consider MBRP’s T409/T304 stainless options in the same diameter/bend style where available.
Do the 12" legs include the curved section?
No. Each leg measurement is straight length from the bend, designed to simplify trimming and placement during fabrication.
What other bends pair well with MB2017?
For 4" systems, combine with MB2016 (45°) or MB2029 (180°). If you need both a 45° and 180° in one piece, MB2030 is a smart alternative.
