What’s the difference between Armor Pro, Plus, and Lite?
Armor Pro = T304 stainless (best corrosion resistance), Armor Plus = T409 stainless (high durability/cost balance), Armor Lite = aluminized steel (budget-friendly). Choose based on climate and budget.
Do I need welding or special tools?
No welding is required. The kit is designed as a bolt-on installation with supplied clamps and hardware.
Is the sound obnoxious on long drives?
No—this kit targets a street-profile sound: assertive under throttle while remaining comfortable at cruise.
