I purchased my JBA catback a couple months back. Before installing it myself in the garage, I called the local MIDAS shop for an estimate. MIDAS was going to charge me $150 for the install. I decided to save some money & installed it myself (pretty simple & straight forward). Afterwards I went to MIDAS to have them tack weld the joints for $23. Since you mentioned that you can weld, you can pretty much do everything yourself...Good luck...
