Probably just the bumperettes....I think its the same as an 02+ rear bumper.

Here is a GT3 rear.....

 

It looks to me like it may be a bit lower and have a little different aerodynamics.

 

same as the 02+ rear bumper....

 

my modified TT bumper....

 

All said and done with cost of bumper altering it and paint install, etc what did it cost you to get that turbo bumper put on?

 

less than 1k for bumper and paint....and modding I think.....It just depends on how much you can get a used TT bumper for...I got a perfect one for $250. The modding is about $500, and the paint and prep another couple hundred...now you also need the side grills....you can put mesh in there for cheap...I used the factory C4S grills...I think they were like $150 a pair...and you need to used the C4S exhaust extensions or have a muffler shop extend your tips as the TT/C4S exhaust is in a different place. I had a muffler shop custom make my tips and route them for $300. They would have just moved them and made an extension for like $50. It may seem like alot but the TT "look" bumpers are like $1000 and then you have more paint and prep than the poly bumper and it never looked right to me.

 

im selling my stock bumper for the 996 narrow body in mint condtion. if you want it let me know?
