Overall great feel and functionality, it took longer than I thought to remove the factory headers and Y-pipe but installing a new plumbing was fairly easy and straight forward , in General lasted all day. It takes a while for the store finish to burn through and stink, but that's it. Be sure to tighten! From the Y-tube bolts to the header, mine has come loose 2 times and today is my 3rd time buying locknuts
