Miles are unknown. I'm the second owner. However the paper tag on the turbo with writing in pen is still on there and readable. That tells me the previous owner probably didn't use it on a daily driver, or just didn't have it long and didn't live in a wet climate. It's from south tx so it's been really dry here. Also tags on the clamps with the sizes and part numbers are still on most o the clamps as well. The kit also includeds a brand new, never installed gm ypipe without convertors. This is the export y pipe that fits perfectly to factory manifolds but without cats. Not a hacked up piece.
