Borla 140545 S-type split side exit cat back exhaust. Borla has 3 levels of exhaust sound and this is the mid level. Dual exhaust tips are chrome that need some polishing. I took them off my Silverado 1500 with just over 9k miles. I sold the truck.
I've always liked the sound. Cash only. No shipping. One of the pics describes which Silverado or Sierra it fits. Also double check Borla website.
