thats odd, what part is rubbing? i have the cobb FMIC and cobb sri so id imagine theyre designed not to interfere with each other but the turboxs FMIC is similar in design to cobb, i think the cp-e with it's larger diameter piping than the cobb sri might be the issue... my sri DOES rub against the recirc tube but thats no issue cause silicon on silicon wont be any issue.
can you guys get some pics of where its rubbing?
