wat the best sounding loudest racing exhaust for the 997 TT?

 

Here we go....
The loudest is gonna be muffler/cat bypass pipes. After that there are any number of "loud", "moderate" or "export" mufflers from various manufacturers. Start witha search and try and listen to as many as possible, in person would be best. Then choose one, they're all pretty good.
Personally I like the Fabspeed Gen 3, they're awesome!

 

Fabspeed 997TT Imported Sport Racing Catalytic Converters with Muffler Bypass Pipes $1,995.00

 

For a 'racing' application, def the fabspeed bypass pipes, even consider the cat bypass. Nice thing about their system is that you can swap muffler cans in/out as necessary.

 

its about 2 grand is it rly worth it??

 

Another option would be the cargraphic "export" version. It's one of the louder exhausts available but not as loud as those straight pipe options.

 

Any videos of the fabspeed racing cats?

 

you will find videos of all their setups
