I'll second this, although there is a very good youtube video for doing the CPS without removing anything else. Stuck? Pull more parts off lol. You'll get better at it.While working on these cars is sometime challenging at best, the old method of removing more than needed is the better approach. Also have a small ratchet that holds screwdriver bits works well for tight spaces. Removing the down pipe makes the job simple, and if you take the down pipe off often the bolts don't end up breaking on you later.Add up the time spent struggling vs. disassembly would outweigh the aggravation. On the upside you learn how the whole car comes appart.
