I purchased driver and passenger side Catifolds and a passenger rear crampon/center tube from a now defunct Shopify store called AZ Race Place. Shortly after installation, the headers broke and exhaust fumes began pouring through the deflectors into my Frontier's cab. Now I'm buying new headers 16 months and 12,000 miles after paying a small fortune to have them installed. Too bad I didn't see all the complaints before buying. Learn from my mistake: Saving now will cost you dearly next year.
