id say no. the motors are completely different. the 996/997/991 GT3 & turbos have the more robust, desired mezger based motor. this is why they do not suffer the IMS issues that the base model 911's, boxtsers & cayman do/can have. the mezgers do their own issues like cooling line failure so they are not perfect either.

I can not say for sure, but id be very, very surprised. check part numbers in the pelican catalog for headers, cats, & mufflers. that might clue you to interchangeability..
