I'm lost .... My mate asked me to buy exhaust system for his hawk eye sti scooby, He wants blitz nur spec r. just can't find one... Thought found for gda/gdb ,, Question is there a diference between them , gda, gdb.gdf. If there is do you know where can a get the gdf one.

The scoob is 2.5 eu do, not jap spec.

Cheers pals
