ok i just purchased an OBX header for my 95 2.2L OHV and the front pipe that came with it is a 2 1/2 inch opening while the magnaflow high flow direct - fit cat has a 2 inch opening. so my question is will this pose a problem as far as performance or installation?
from what i know there is no direct fit for the cavalier. and if its only 2 inches you should look into getting a larger one
the 95-97 early 98's have bolt in cats , and a few companies make them
the obx should be 2 1/4" not 2 1/2
