Before i mounted the itb setup, i modified the exhaust somewhat, to get it to not make my ears bleed.
Improved the Y on the headers, wich was a heavy, ugly pos hack job, welded with the worst mag welder ever created, and replaced it with just a vband, also made and fitted a vband and compensator to a new muffler. I don't have pictures of the rear muffler, but it is a RB turbo muffler i got from a friend, and it is way better than anything i ever had before.
Some videos, before and after. No rear muffler on the befor vids, gave it to a friend who wanted it on his rx8.
