if you want longer tubes for each cylinder, they why not put the cats on your mid-pipes instead of your headers? if you buy that logic, then you can re-install your old mid-pipes (they might be of a restictive diameter, however) add cats to your current aftermarket midpipes, or buy a set of midpipes with sportcats from one of many vendors. either way, you would probably need to add a bung after the cat and extend your sensors.

another option is to wait for che. from all reports a 987/cayman exhaust will fit on a 986. che will be selling catless headers for the 987 shortly (for some odd reason there are currently no cheap chinese headers for the 987 like on the 986). then you can just find an oem take-off for the mid-pipes and muffler - better sound, bigger diameter, cats located well downstream at the muffler.
