I have a 5 speed. I purchased a catted invidia divorced DP and I am about to install it with the vf48. My friend is installing it this weekend so I will have a better answer but I do have a titek 02 07 for STI installed but i am not sure if it was only for 5 speed. I purchased it from SubieSleeper along with his exhaust a couple of years ago. If I can get ahold of him, I will let you know.
