The exhaust tips are constructed of T304 Stainless Steel and built to the highest possible quality standards. Finished surfaces are mirror polished with a logo engraved or laser etched logo. (Where applicable). The tips need to be fitted by welding or other means. Some tips are direct bolt/clamp on style, it depends on your specific vehicle. Please check your rear bumper/diffuser for fitment.  Adjustments may need to be made to fit wider tips.
