Borla builds their cat-back exhaust systems from 100% T-304 aircraft quality stainless steel, not mild steel, not aluminum, not coated aluminum.
While coating substandard materials like mild steel may prolong life, these coatings suffer and typically fail at the weld points. Stainless steel maintains true to form and function at all points for superior corrosion protection. As the guys at Borla say,
''When you compare coated materials to 100% T-304 stainless steel, it's like comparing gold-plated metal to solid gold!''
