the dumbasses at midas near me (had them weld on a stainless steel tip to my stainless steel muffler as it came with a ricey 4" tip) used regular steel weld wire (did a shitty job too) to weld the stainless steel tips together...guess what...it is rusting and there is a hole at the weld already

if you are ever going to bring your car in the shop for estimates...do it right and bring it to the dealer or a trusted mechanic...the meinike and midas guys have little to no training or understanding of cars
