Could have been cleaned up a little better. I did order the mill finish, but still edges are very sharp, and welds look rushed. The pipe coming out of the muffler wasn't 2" ID, so I had to have a machinist make my v-band clamps fit before welding. Also, it did take almost 2 months to get, but I did get a partial refund for having to wait longer though. As this was a Stainless Works product and out of hands I don't blame them( you guys are great!). All and all, these are just race car problems lol, and very happy in the long run, cant wait to hear the car when shes done!
