It was on the truck when I bought it. I think it is a full Flowmaster 50 series kit. Both tips turn out behind the rear tires. Its not to loud, I think I might go with a 40 series Flowmaster muffler to get that deep throaty growl sometime in the future.

If you stick with your stock 17's I think you can run 35x12.5R17. You will have to trim the valance like I did but I think it will fit. Ask wandell he should know if it will fit or not.
