I have a new in the box Corsa sport muffler. The caseing of the muffler is dented from shipping but is only cosmetic and won't hurt the function of the muffler. The part# is 14637 and lists as a GM suv muffler. I am sure you could install this muffler in place of your factory truck muffler easily. This muffler is $400.00 new from Corsa.
