emissions removal, HP gains?
im in MN and they dont test for emissions and so i dont need it and all it does is cause clutter under the hood, plus im building up my 305 so i figure why not
so what kind of HP gains will i see if i removed all the emissions equipment from my car? with hedman headers

none, might remove a little weight, also lower gas mileage due to removal of the EGR valve.

You won't see any gains unless you gut the stock cat which is useless anyways. Even a 3" cat will not rob performance when time comes to change your exhaust.
