Depends if you trust exhaust centre/garage to just do work needed. a swine of a job to do with no ramps, you will need car to be high enough to manoeuver sections into position. Part may cost you nearly as much as having done. If D-I-Y you will need to remove mid section and rear sections from front section without damaging front section join (often self-welded!) and make sure you don't bash or damage Catalytic converter if fitted (very expensive!) there maybe heat shields to remove and refit for access, and you may need to replace rear section rubber mounts which you have to disconnect first. Good Luck!!
