I did a little experimenting with the directional flow of my BCT baffles. I decided to install the baffles in the opposite direction from the instructions. This places the restrictor eyelet BEFORE the venturi. I was curious what effect I would get. In the end I didn't notice much difference. I did feel a slightly better throttle response right off idle, but I also experienced a much louder decell"crackle" when shifting gears. The exhaust tone of the acceleration seemed to be unchanged. I did not like that drag pipecrackle, so I ended up flipping the baffles back to the suggested direction with the restrictor after the venturi, and the decell crackle is once again more subdued...
