My 99 tip came with a CAI that the PO did ? Basically cut the intake tube and stuck a KN on it. Amazingly it didn`t affect the MAF. I changed the filter and installed an Injen heat shield. When I had the IMS done at Mantis in Oakville I had them install one of their underdrive pulleys. It`s a 5" so same belt and very little effect on the p/s. I also installed a set of OBX headers. It does pull better but I find lags a tiny bit a low rpm but once its over 3 it really starts to pull and sounds great. My 99 has two cats without a bypass .:dance:
