I installed my own Corsa exhaust and Gibson headers myself and in that order. The Corsa System was so easy to install. The hardest part (which was not hard, took 5 minutes) was cutting two pipes in front of the muffler. All you need to do this is a Sawzall (reciprocating saw). Support the muffler when you do this or it will drop when you cut the pipes.
The headers were harder to install. If you are a tool guy and have worked on cars before, you could do the install. If you are a mechanical novice, I would not attempt it.
