well keeping the foglights sounds nice. when i got my car there was already an fmic in it, and the foglights were taken out because the piping would get in the way. so i bought foglights and now i need better piping or a new fmic. i have the greddy 18r, and the outlet comes out of the front of the i/c, runs behind the bumper and under the passenger headlight, and then up through the stock uic hole and to the t/b. not very good flow.
