GMC Sierra 2013 Peace, mercy, and blessings of God be upon you. I am offering various parts, a complete kit including headers, Y-pipe, and cat-back. The headers are long, and the corsa muffler is original with a lifetime warranty. However, the throttle body is on the Magnaflow output. Original, not 3-inch tires, clean, only used for a month. Dune tires, size [unspecified], used for approximately 3 months. Spectre filter on a K&N intake. Yukon rims, approximately 2005 model, clean and guaranteed, no stickers or vibrations. A Karrash muffler on the original Magnaflow output. The sale is flexible, make your offer and take it, but be reasonable.
