New Reproduction 307-S25 replacement exhaust tips for 1968-74 A-body vehicles. The original exhaust tips were manufactured in mild steel and chrome plated, a design that did not fare well against the elements and most original exhaust tips deteriorated away after just a few years. These exhaust tips are manufactured in high-luster, never-rust 304 stainless steel and with all proper contours to correctly replace the original and offer an authentic appearance. Original size fits through the rear valance panel on all factory dual exhaust cars. Sold as a pair features a 2-1/2 inches inner diameter.
