Alright, as I was writing that I was thinking of the possibility that it was just marketing, if not anything else..
I just wanted to be sure I wasnt going to cause any damage by increasing airflow to the engine with an intake, and then not improving the front exhaust which is already a restriction zone... so I guess I wont worry about that too much...
Is my 08 downpipe double walled like that? I know that 04+ doesnt have the ubend like earlier GP's do, but I didnt know it was also such a narrow pipe... that looks insanely tight compared to the Hogan one.
