Hi, so I tried to install the VTA Catch Can from BSH, half way through the installation, I found out I was missing two screws to mount the bracket onto the car... I believe this is a issue because of the noise pipe deletion on the 2011. I would like to know what type of screws I need, like what kind of thread is it... I would also like to hear BSH respond about this because I'm very unhappy with the purchase... I did not even get any sticker to stick on the catch can and the catch can looks different (worse) from the product shown by BSH...
