when you took it off, was there a little donut or gasket that needed to go in there inside the connection? if so did you forget it or not put it in correctly?
i checked the donut & the gasket... both are fine. my friends whom had greddy before said it knocked and rattled a lot... therefore it could be something loose within the cat or something. anyway, i ordered apexi exhaust from RPM motorsport from our sponsers here at HAN.. so when i install it.. i will double check it again. hopefully my exhaust come in next week. ordered it on thursday... but haven't got tracking yet...
