remove pre cat?
if i remove my precat will i still pass emissions, have functioning 5th/6th ports? i just want to make it a little bit louder...
i have cone filter --> stock header --> stock pre cat --> stock cat --> 2.5 inch cat-back piping --> mazda speed canisters.
i like the sound it makes now, i just want it to have a little more bass to it.
